Maintenance and Performance Checks 3-12
Gain Accuracy Tests
Equipment
:
DMM, Arbitrary Waveform Generator, Load Resistance,
50
Ω
feedthrough terminator
Preparation:
1. Configure the DMM as follows:
Function: ACV
Range: 200V
2. Connect the 9400 Channel 1 output to the DMM input. Attach
the load resistance at the input terminals of the DMM
3. Configure the Waveform Generator as follows:
Frequency: 1kHz
Output: On
Amplitude:
As required for the test
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. Perform Gain Accuracy tests on channel 1 and channel 2
outputs using Table 3-12
2. Use the same procedure to check channels 3 and 4

Test Procedure
1. Using the variable vertical adjustment on the oscilloscope,
adjust the vertical trace to show exactly 6 vertical divisions
2. Perform bandwidth, large signals tests on channel 1 and
channel 2 outputs using Table 3-13
3. Use the same procedure to check channels 3 and 4
