HP 75000 SERIES C User Manual

Spurious Signal
This procedure tests the HP E1440A sine wave output for spurious
signals. Circuits within the HP E1440A may generate repetitive
frequencies that are not harmonically related to the fundamental
output frequency.
Specifications
All spurious signals must be more than 60 dB below the fundamental
signal or less than
-85 dBm, whichever is greater.
Equipment Required
Spectrum Analyzer
Mixer Spurious Procedure
1. Connect the HP E1440A signal output to the spectrum analyzer
500 (RF) input and the HP E1440A REF INput to the analyzer
10 MHz reference output, as shown in Figure C-4.

2. Set the HP E1440A as follows:
Function Sine
Frequency
2.001 MHz
Amplitude
63.24 mV(p-p)
OUTPUT Vxi;":FUNC S1N;:FREQ 2.001E6;:VOLT:AMPL 63.24MV"
3. Set the analyzer controls as follows:
Center Frequency
2.001 MHz

4. Adjust the spectrum analyzer to reference the fundamental to the
top display graticule.
5. Without changing the reference level, change the spectrum
analyzer center frequency to
27.999 MHz to display the 2:l
