To troubleshoot source and calibrator out failures
Use this test when the analog source or calibrator is suspected of failing
and all self tests listed before the ADC in the Self-Test Troubleshooting
Guide on page 1-32 passed.
1 Check the sine wave output.
a Set the power switch to on ( l ).
b Using a BNC cable, connect an oscilloscope to the SOURCE
output.
c Set the oscilloscope as follows:
CH1 V/div 400 mV/div
Input Impedance 50
Ω
CH1 Coupling dc
Probe Atten 1
Display Mode Real Time
Time/div 200 ns/div
Trigger Trg’d Sweep

e The oscilloscope should display a 1 MHz, 2 Vp-p sine wave with no
dc offset. If the signal is incorrect, go to Step 7.
This is only a quick check of the source sine wave. If the source is
suspected of failing at a specific frequency or amplitude, check
