1710J-Series Waveform Monitors
2. Connect the AC power cord to the variable autotransformer. Turn power on
1710J-Series Waveform Monitor and set the autotransformer for either 110
or 220 Volts.
3. Use a 75
W
coaxial cable to connect a composite color bar signal from the
television test signal generator to the CH B input. Terminate the remaining
side of the loop-through with a 75
W
end-line terminator.
The requirement is AC input range 90–132 V or 180–250 V.
1. Vary the autotransformer from 90–132 V or 180–250 V.
2. Check for stable operation over the voltage range.
3. Return the autotransformer to 110 or 220 Volts.
The frequency requirements are
H
Frequency 100 kHz
±
100 Hz
H
Synchronizes 1 Line and 2 LINE Sweep (free runs in 2 FLD)
1. Connect a X10 probe from the frequency counter to the blue CRT lead on the
main circuit board.
2. Display the CAL signal at the 2 LINE sweep rate.
3. Check that the frequency of the Calibrator is 99.9 to 100.1 kHz.
4. Check that the Calibrator is synchronized in both 1 LINE and 2 LINE sweep.
5. Check that sweep free runs in 2 FLD sweep.
The requirements are stable sweep synchronization are
H
Internally 40 IRE (300 mV)
±
6 dB
H
Externally 143 mV to 4 V
1. Check that the 1710J-Series Waveform Monitor can be synchronized to the
amplitudes shown in Table 6–3, using the television test signal generator.
Check both 2 LINE and 2 FLD sweep for stable triggering.
