Maintenance and Performance Checks 3-10
Amplitude: 1
V/div
2. Connect the 9400 Channel 1 output monitor to the Oscilloscope
input.
3. Configure the Waveform Generator as follows:
Amplitude: 8
V
Function:
Square wave
Output: On
Frequency: 50
kHz
4. Connect the waveform generator to Channel 1 input. Terminate
the waveform generator using the 50
Ω
feedthrough terminator at
the 9400 input
Test Procedure
1. Using the variable vertical adjustment on the oscilloscope,
adjust the vertical trace to show exactly 6 vertical divisions
2. Perform rise/fall time tests on channel 1 output using Table 3-
10
3. Use the same procedure to check channels 2, 3 and 4
