〔産業上の利用分野〕
本発明は計測器に関し、特にオッシロスコープに関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to measuring instruments, and more particularly to oscilloscopes.
従来、この種のオッシロスコープは、左かう右へ掃引が
行われていた。Traditionally, this type of oscilloscope has been swept from left to right.
上述した従来のオッシロスコープは、左から右へ掃引が
行われているので、時間的に早い時点の信号は左に、遅
い時点の信号は右に表示される。Since the conventional oscilloscope described above sweeps from left to right, signals at earlier points in time are displayed on the left and signals at later points in time are displayed on the right.
これは通常の時系列信号を表示する場合には時間軸が左
から右へ表示されるので都合が良いが、直列信号でLS
BからMSBK順に流れる信号(例えばR8−232C
規格の信号)を表示すると、LSBが左に、MSBが右
に表示され、慣習的な表示すなわちMSBが左、LSB
が右の表示とは逆となシ、読み取シ誤シを起こすという
欠点がある。This is convenient when displaying a normal time series signal because the time axis is displayed from left to right, but when displaying a serial signal, LS
Signals flowing in order from B to MSBK (e.g. R8-232C
standard signals), the LSB is displayed on the left and the MSB is displayed on the right;
However, if the display is opposite to the one on the right, it has the disadvantage that it can be read incorrectly.
本発明の逆掃引オッシロスコープは、掃引反転回路を有
している。The reverse sweep oscilloscope of the present invention has a sweep inversion circuit.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第1図は本発明の逆掃引オッシロスコープの基本構成図
である。信号人力1よシ入力される被観測信号は、垂直
増幅器2によシ増幅されてCRT8の垂直偏向板9を駆
動する。また垂直増幅器2の出力はトリガ回路3に入シ
トリガ信号11を発生 ゛する。トリガ信号11によ
って、のこぎシ波発生回路4は掃引波12を発生する。FIG. 1 is a basic configuration diagram of a reverse sweep oscilloscope according to the present invention. The observed signal inputted from the signal input 1 is amplified by the vertical amplifier 2 and drives the vertical deflection plate 9 of the CRT 8. The output of the vertical amplifier 2 also enters a trigger circuit 3 to generate a trigger signal 11. In response to the trigger signal 11, the sawtooth wave generating circuit 4 generates a sweep wave 12.
掃引反転回路5では、掃引波12の極性を反転した逆掃
引波13を作る。切換スイッチ6は、掃引波12か逆掃
引波13のいずれかを選択し、水平増幅器7によりCR
T8の水平偏向板10を駆動する。The sweep inversion circuit 5 generates a reverse sweep wave 13 by inverting the polarity of the sweep wave 12. The selector switch 6 selects either the sweep wave 12 or the reverse sweep wave 13, and the horizontal amplifier 7 selects the CR
The horizontal deflection plate 10 of T8 is driven.
第2図は掃引波12の波形であり、第3図は逆掃引波1
3の波形である。Figure 2 shows the waveform of the sweep wave 12, and Figure 3 shows the waveform of the reverse sweep wave 1.
3 waveform.
第4図はディジタル信号(1010)をLSBから順に
直列信号として信号人力1に入力し、切換スイッチ6に
よシ掃引波12を選択した時のCRT8の表示である。FIG. 4 shows the display on the CRT 8 when the digital signal (1010) is input as a serial signal from the LSB to the signal generator 1 and the changeover switch 6 selects the sweep wave 12.
第5図は同様に、逆掃引波13を選択した時の表示であ
る。第4図では慣習的に0101と読み取ってしまうが
、第5図では1010と読み取れる。Similarly, FIG. 5 shows the display when the reverse sweep wave 13 is selected. In FIG. 4, it is conventionally read as 0101, but in FIG. 5, it is read as 1010.
以上説明したように本発明は、掃引方向を右から左へ行
うことによシ時系列を逆に表示できるので、LSBから
MSBへ順に入力される信号をMSBを右側に表示でき
、慣習的に読み取れる効果がある。As explained above, the present invention can display the time series in reverse by performing the sweep direction from right to left. Therefore, the signal input from LSB to MSB can be displayed with the MSB on the right side. It has a readable effect.
