PSA Series Spectrum Analyzer (Option AYZ)
Be sure to refer to “Spectrum Analyzer Retrofit Requirements” on page 9 for instrument
requirements for the PSA Series spectrum analyzers. The Agilent Technologies PSA Series
spectrum analyzers contain an extensive menu of functions that help with millimeter
measurements. The following examples explain how to connect external mixers to the
spectrum analyzer, how to choose the band of interest, how to 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 2-2.
Figure 2-5 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.)
