Performance Verification 5-4
2.
Set the DMM to ACV measurements (RMS).
3.
Connect the Model 3155 output to DMM input. Termi-
nate the output with a 50O feedthrough termination. Set
the amplitude and verify DMM reading as follows:
3155 SETTING
7.50 V
750.0 mV
Accuracy Specifications:
± (1% of reading +1% of amplitude +200µV), ± 400mV window
± (1% of reading +1% of amplitude +2mV), ±4V window
Equipment: DMM, 50O feedthrough termination

2.
Set the DMM to DCV measurements
3.
Connect the Model 3155 output to the DMM input. Ter-
minate the output with a 50O feedthrough termination.
Set the Model 3155 offset and verify the DMM reading
as follows:
OFFS SETTING
±2.500 V
4.
Change the Model 3155 AMPL setting to 100 mV. Set
VOLT:OFFS and verify the DMM reading as follows:
OFFS SETTING
±250.0 mV
