9100A/9200A/9400
Maintenance and Performance Checks 3-16
Function: ACV
Range: 200
V
2. Connect the 9400 Channel 1 (then 2, 3 and 4) output to the
DMM input. Terminate the signal with the load resistance at the
DMM input
3. Configure the waveform generator as follows:
Waveform: Sine
Frequency: 1
kHz
Amplitude: 8 V
4. Connect the waveform generator output to the 9400 Channel
1(then 2, 3 and 4) input. Use 50
Ω
feedthrough terminator at the
9400 input
Adjustment:
1. Identify the trimmers for each channel and make the
adjustments below for a DMM reading of 141.42 Vac, ±1%
2. For channel 1, adjust RV6 (course) and RV1 (fine)
3. For channel 2, adjust RV8 (course) and RV2 (fine)
4. For channel 3, adjust RV10 (course) and RV3 (fine)
5. For channel 4, adjust RV12 (course) and RV4 (fine)

Outputs
Equipment: Waveform Generator, Oscilloscope, x100 high voltage
probe, Load Resistance, 50
Ω
feedthrough terminator
Preparation (use the same procedure for channels 1 through 4):
1. Configure the oscilloscope as follows:
Time Base: 100 ns/div
Amplitude: 10 V initially, then use variable mode to
adjust to 6 vertical divisions
2. Connect the 9400 Channel 1 (then 2, 3 and 4) output to the load
resistance. Connect the oscilloscope using the x100 probe
across the load resistance
3. Configure the waveform generator as follows:
Waveform: Square
Frequency: 50
kHz
Amplitude: 8 V
4. Connect the waveform generator output to the 9400 Channel
1(then 2, 3 and 4) input. Use 50
Ω
feedthrough terminator at the
9400 input
Adjustment:
1. Identify the trimmers for each channel and make the
adjustments below for rise/fall time of <1
μ
s
2. For channel 1, adjust C43
3. For channel 2, adjust C64
4. For channel 3, adjust C85
5. For channel 4, adjust C113
