I
1. Sine wave Test. Connect the HP E1440A signal output through a
5032 feedthru termination to the AC digital voltmeter input.
2. Set the HP E1440A as follows:
High-Voltage Output
Off
Function
Sine
Frequency 100 Hz
Amplitude 3.536 Vrms (10
V(p-p))
DC Offset
0 V
OUTPUT Vxi ; " : OUTP : AMPL OFF ;
:FUNC S1N;:FREQ 1E2;
:VOLT : AMPL 10 ;
:VOLT:OFFS 0;
: CAL? "
3. Read the AC voltmeter. Change the HP E1440A frequency to 1
kHz and 100 kHz and repeat.
OUTPUT Vxi ; " : FREQ 1E3"
OUTPUT Vxi ; : FREQ IE5"
Verify that all three voltmeter readings are between 3.455 and
3.617 Vrms
(f 0.2 dB).
