Description of the drawings
Fig. 1 is the utility model principle figure.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clear, complete elaboration.
As shown in Figure 1, a kind of automatic test case for radio communication detection, logical mainly for detection of public's movement
Believe system base-station and repeater, base station/intermediate station of private network analog/digital cluster communication system, Vehicle mounted station and MS terminals
Radio launching target and reception index；It includes main control board, high power attenuator, power splitter, filter and channel
Selecting switch；Automatic test box has USB interface for power to automatic test box and for the reception and registration of automatic test box
The RS232 interface of the communication instruction of upper computer software, while it being respectively provided with a port RF-RX In, the ports RF-RX Out, from
The instruction that dynamic test box is issued to host computer passes to the main control board in case, and main control board connects with channel selection switch
It connects, high power attenuator is connect with the ports RF-TX/RX, and high power attenuator also passes through channel selection switch and filter and work(
Device connection, the power splitter is divided to be connect with the ports RF-RX In, filter and power splitter also pass through channel selection switch and RF-RX
The ports Out connect, and under main control board control, channel selection switch will be switched in different filter paths, extraneous
Electromagnetic wave signal through channel selection switch branch and then will pass through filter passes to test instrumentation by high power attenuator
In.
In the present embodiment, the filter is by least three (narrowband trap) filters (figure median filter 1,2,3 ...)
And (wide-band microwave) high-pass filter composition；
The main passband of RX/TX links is all the way (CHA1)：Design all kinds of numbers of main band connection frequency covering, simulation cluster mobile communication
System equipment, 50 Ω of standard In/Out impedances.Major function is the launching target parameter for testing all kinds of intercoms, including：
The technical indicators such as transmission power, carrier wave frequency deviation, occupied bandwidth, adjacent-channel power, band spurious.
Emit four tunnel (CHA2-CHA5) of link test filter path：The filter for including various frequency ranges, for filtering out master
Emit the frequency spectrum of signal so that equipment under test band stray signal is able to show in frequency spectrograph, without because by frequency spectrum
Instrument dynamic range it is inadequate, be hidden among noise.
High-pass filter realizes that higher hamonic wave frequency range tests spurious emissions index so that equipment under test band stray signal is surveyed
Full frequency band is shown in examination frequency range 9KHz-12.75GHz, without being influenced by trapper higher hamonic wave free transmission range.
It is designed as two paths selecting switch, entire test box is while supporting each channel switch to switch at high speed, power supply
