Abstract

PURPOSE:To put a measurement system in normal operation by emulating a function corresponding to an input command on the side of the measuring instrument even when a command inputted from a host computer is different from commands defined on the side of the measuring instrument. CONSTITUTION:The host computer 10 sends the command to the measuring instrument 15. This instrument 15 receives the command signal through an external interface 2 and sends it out to a command reference part 4. Then the reference part 4 checks whether or not the input command is a defined command stored in a command table 3. This reference part 4 sends the command to a command translation part 6 when the input command is the defined command or sends an error signal and this command signal to a defined command signal generation part 5 when not. Then the undefined command signal from the generation part 5 is converted by a command emulation program execution part 11 into a defined command equal to the undefined command and inputs it to the translation part 6.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Application Field of the Present Invention The present invention relates to a measuring device that is equipped with a computer function and that operates under the control of commands input from an external host computer or the like.

<Prior art> (Figure 6) Conventionally, measurement devices such as spectrum analyzers and oscilloscopes, which are equipped with computer functions themselves and whose measurement parts are controlled by commands from an external host computer, have been in practical use. has been done.

FIG. 6 shows such a conventional measuring device 1, in which a command input from an external host combination 1-10, for example "CF1000MHz" for setting the center frequency to 100MHz, is sent to the measuring device. 1, the measuring device 1 receives this command at the external interface 2 and sends it to the command reference section 4. The command reference section 4 checks whether the command "CFloooMHz" is a command defined in advance in the command table 3 (hereinafter referred to as a defined command). If it is not a defined command, an error signal is sent to the undefined command signal generator 5, and the undefined command signal generator 5 outputs this command to the external interface 2 as an undefined command signal.

If the input command is a fixed j command, the command reference section 4 sends this command to the command translation section 6.

Upon receiving this command, the command translation section 6 checks the numerical range, etc., and if the data value in the command exceeds a predetermined numerical range, it sends a signal to the translation error signal generation section 7 as a translation error. The translation error signal generator 7 sends the translation error signal to the external interface 2.
Output to.

External interface 2 sends undefined command signals and translation error signals in accordance with host computer 10 requests.

If the command input from the host computer 10 is a definition command of this measuring device 1 and the numerical range etc. are normal, this input command is executed by the command execution unit 8.
This is executed to set the measurement unit 9.

Problems to be Solved by the Present Invention> However, in conventional measurement devices that can be controlled by a host computer, the interface is almost uniform (GP-18, R823
2C), but the command system is often different,
A series of measurement programs created for a certain measurement device is
In the case of a large system program, it cannot be used with other measuring instruments with different command systems, and all commands in the program created on the host computer must be changed to commands suitable for the measuring instrument being used. The problem was that it took a lot of time and money.

The present invention solves these problems, and even if a command input from a host computer etc. is different from a command defined on the measurement device side, it can be input on the measurement device side without changing the program on the host computer side. The purpose is to provide a measurement HM that allows the measurement system to operate normally by emulating functions according to commands, and to provide versatility to measurement programs created for other measurement devices. .

Means for Solving the Problems> In order to solve the problems described above, the measuring device of the present invention provides the following method: When a command input from an external device is different from a command defined on the measuring device side, The measuring unit is configured to convert a command into a predefined command (or a defined command string) equivalent to the above command to control the measurement unit.

Effect> Therefore, even if the measuring device of the present invention receives a program created for another measuring device with a different command system, it can perform the same measuring operation as the other measuring device.

Examples of the present invention> Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 shows a first embodiment of the invention.

In FIG. 1, 15 is a measurement device, 2 is an external interface, 3 is a command table, and 4 is a command input from the host computer 10 via the external interface 2 that matches any of the defined commands of this measurement device 15. The command reference section 5 refers to the command table 3 to determine whether the input command is to be executed or not. An undefined command signal generating section outputs the input command as an undefined command, 6 is a command translator, 7 is a translator error signal generating section, 8 is a command execution section, and 9 is a measuring section.

Reference numeral 11 denotes a command emulation program execution unit for receiving an undefined command @ sign from the undefined command signal generating unit 5 and converting it into a defined command or a defined command string for the measuring device 15.

12 indicates a command that is equivalent to the defined command of this measuring device 15 but has a different expression among the commands of other measuring devices.
This is an input operation unit for creating a program in the command emulation program execution unit 11 for converting into a defined command.

Note that instead of creating a command conversion program using the input operation section 12, a plurality of command conversion programs created in advance are installed in the command emulation program execution section 11, and a selection key (not shown) is used. You may also select one of them.

FIG. 2 is a flowchart showing the operation of the embodiment shown in FIG. 1, and the processing procedure will be explained below.

First, a command is sent from the host computer 10 to the measuring device 15. In the measuring device 15, the external interface 2 receives this command signal, and the command reference section 4
(Step 1).

The command reference section 4 checks whether the input command is a defined command stored in the command table 3 (step 2.3).

If the input command is a definition command, the command reference unit 4 sends this command to the command translation unit 6, and if it is not a definition command, it sends an error signal and this command signal to the undefined command signal generation unit 5. send.

The undefined command signal from the undefined command signal generation section 5 is converted into a defined command equivalent to this undefined command by the command execution program execution section 11, and is input to the command translation section 6 (step 4-6).

For example, assume that the following program is input from the host computer 10.

100 WRITE A101: “EMT xxx” 110 WRITE A101: “RLJN” 120 WRITE A101: “CF 10MZ” 30 Line number 100 indicates that the command for controlling the measurement unit from host combination 1-Y 10 is an undefined command. This is a command to emulate only when there is (A10
1 is the address of the measuring device 15), and line number 110 is the command emitter 1 rate program execution unit 11 of the measuring device 15.
The command to start the measurement unit 9 from line number 120 onwards
This is a control program.

On the measurement unit [15 side, the following program is executed.

10 DIM A$ (256) B$ (4), C$ (256) 100 EVENT ON 12, *EREML
T 500 5TOP 1000 *EREMLT 1010 LET A$= “C$=”

C$= RIGHT$ (A$, 252> 1080 PUT B$, C$1090
RETURN 1100 *N1 1110 IF A$(0)<>”S”GO
TO*N2 That is, after the three variables are set, the conditions for emulation at the time of an undefined command, and the jump destination <1ooo address) are set, the program for controlling the measurement unit 9 from the host computer 10 is executed. (Row numbers 10-500).

If there is an undefined command during this execution, the emulation program will start with line number 1ooo>, and the area used by the replacement program will be made clear (line number 10).
10), an undefined command is read (line number 1020).

Next, judge this read undefined command character by character (line numbers 1030 to 1050) and determine if this command is 'C
F”, “”CNF which is synonymous with this command
” command reference section 4.
and the original program (500 after line number 100)
Return to the previous program (line numbers 1060 to 1090)
).

If the undefined command is not 'CF'', the program moves to the check program starting from line number 110, converts it to a defined command with the same meaning, and returns to the original program.

Commands converted into definition commands in this way are checked in the command translation unit 6 for numbers (if ranges, etc.). A signal is sent to the translation error signal generating section 7, and the translation error signal is sent from the translation error signal generating section 7 to the external interface 2 (steps 7 to 9).

The external interface 2 outputs the translation error signal from the translation error signal generator 7 in accordance with a request from the host computer 10.

If the numerical range of the command is normal, the command translation unit 6 sends the command to the command execution unit 8, and makes settings corresponding to the command in the measurement unit 9 (step 10). Based on this, the measurement unit 9 receives a signal from, for example, the object to be measured and performs measurement.

FIG. 3 shows a second embodiment of the invention.

In this measuring device 16, instead of inputting the command converted by the command emulation program execution section 11 to the command translation section 6 as in the embodiment shown in FIG. 1, the command is inputted to the command reference section 4, and the converted command I decided to check it again.

FIG. 4 shows a third embodiment of the invention.

In this measurement device 17, an applied command translator 8IS13 for translating commands converted by the command emulation program execution unit 11 is provided separately from the command translation unit 6.

By providing the application command translation section 13 separately in this way, even if it becomes necessary to add or change the internal standard commands (definition commands) when creating a 10-gram for conversion of the command emulation program execution section 11. ,
The applied command translator 13 can be used to translate and execute additional commands without changing the command translator 6.

FIG. 5 shows a fourth embodiment of the invention.

This measuring device 18 is capable of selectively sending a command received by an external interface to either the command reference section 4 or the command emulation program execution section 11 via the switch 14. . In addition, the switch can be set to 4M using software.

That is, when the following program is input from the host computer 10, 100 WRITE A101: "EMT FULL" 110 WRITE A101: "RUN" 120 WRITE A101: "CF IOMZ" According to the command at line number 100, the measurement unit 9 All of the control program (from line number 120) is input to the command emulation program execution unit 11.

On the measuring device 18 side, the program shown below is executed using the above program.

10 DIM A$ (256) 8$ (256n, C$ (256)100
EVEN 0N13, *FLEMLT 00 001 010 020 030 TOP *FLEMLT LETA$=” ” B$2 “” READ #1. A$ IF A$=<> CF 10MZ″GOTO*N 11040

PLIT A$ 1110 RETLIRN 1120-f:N2 That is, it is specified that all programs for the measurement unit 9 from the host computer 10 are emulated,
Emulation begins (line numbers 10-1000).

Similarly to the above, the last input command in which the variable area has been initialized is read out (line number @1010.1020).

Hereafter, the read commands are sequentially converted into definition commands and the program for the original measurement unit 9 is executed (
Note that among the multiple commands indicated by line number @1090, 5PF1RBW is a definition command for setting the span frequency and IF bandwidth, respectively.

In this way, by executing the created (or selected) program in the command emulation program execution unit 11 for all commands from the host computer 10, not only commands but also data can be converted.

Note that the command emulation program execution unit 11
In addition to the conversion program stored internally, the conversion program can be easily set from the outside using an external storage device such as a floppy disk, or the internal conversion program can be stored on a floppy disk and used in other devices. It may be configured to do so.

Effects of the Present Invention> As explained above, according to the measuring device of the present invention, even if the command input from the external device is different from the command predefined in the measuring device, the program of the external device can be changed. It has the special effect that programs created for other measurement devices with different command systems can be used as they are for this Sli&.
