1. Set the HP E1440A output as follows:
High-voltage Output Off
Function
Sine
Frequency
20 MHz
Amplitude
999 mV(p-p)
DC Offset
0 V
OUTPUT Vxi;I1:FUNC S1N;:FREq 2E7;
Set up parameters
:VOLT:AMPL 0.999;:VOLT:OFFS 0;"
OUTPUT Vxi
; " : OUTP ON"
Switch on the output
2. Connect the signal output to the spectrum analyzer 50R input.
3. Set the spectrum analyzer controls to display the fundamental
and at least four harmonics. Verify that
all harmonics are at
least
25 dB below the fundamental.
4. Set the HP E1440A to 15 MHz
OUTPUT Vxi;":FREq 1.5E7"
and verify that all harmonics are at least 25 dB below the
fundamental.
