Amplitude Accuracy

Accuracy Specifications (1 kHz):
"(1% of reading +200 µV), to 160 mV
"(1% of reading +2 mV), to 1.6 V
"(1% of reading +20 mV), to 16 V
Equipment: DMM, 50Ω feedthrough termination
1. Configure the Model 3151/3151A as follows:
Function:
Frequency:
Amplitude:
Remote Commands:
:OUTP ON
:FUNC:SHAP SIN
:FREQ 1000
:VOLT 15
2. Set the DMM to ACV measurements (RMS).
3. Connect the Model 3151/3151A output to DMM input. Terminate
the output with a 50Ω feedthrough termination. Set the
amplitude and verify DMM reading as follows:
