PSA Series Spectrum Analyzer (Option AYZ)
The Agilent Technologies PSA Series spectrum analyzers contain an extensive menu of functions that
help with millimeter measurements. Prior to starting this procedure, refer to “Spectrum Analyzer Retrofit
Requirements” on page 11 for instrument requirements for the PSA Series spectrum analyzers.
The following examples explain how to connect external mixers to the spectrum analyzer, choose the
band of interest, store and activate conversion-loss factors, and how to use the signal-identification
functions.
Set up the equipment
1. Connect the signal source and harmonic mixer to the analyzer, as shown in Figure 2-4.
Figure 2-4 Harmonic Mixer Setup
NOTE Agilent 5061-5458 SMA type cables should be used to connect the mixer IF and
LO ports to the analyzer. Do not over-tighten the cables. The maximum torque
should not exceed 112 N-cm (10 in-lb.)
2. On the analyzer, press
Preset, Factory Preset, if present.
3. Select external mixing by pressing
Input/Output, Input Mixer, Input Mixer (Ext).
4. The analyzer frequency band will be set to
26.5 - 40 GHz (A). To choose a different band, press Ext
