Using The Mixers With The 856X Series Spectrum Analyzers; Set Up The Equipment - Agilent Technologies 11970 Series User Manual

Using the Mixers with the 856X Series Spectrum Analyzers

External millimeter mixers can be used to extend the frequency coverage of the 8560 E-Series and
EC-Series spectrum analyzers. (The 8560E/EC Option 002 and Option 327 do not have external mixing
capability.)
The 8560 E-Series and EC-Series spectrum analyzers contain an extensive menu of functions that help
with millimeter measurements. This example explains how to connect external mixers to the spectrum
analyzer, choose the band of interest, store conversion-loss factors, and how to use the optional
automatic signal-identification functions.

Set up the equipment

1. Figure 2-8 illustrates how to connect an external harmonic mixer to the spectrum analyzer.

Good-quality shielded SMA-type cables should be used to connect the mixer to the
NOTE
spectrum analyzer to ensure that no signal attenuation occurs. Agilent 5061-5458
SMA-type cables may be used. Do not over-tighten the cables; the maximum
torque should not exceed 112 N-cm (10 in-lb.).
