Using the Mixers with the 856X Series Spectrum Analyzers

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, how to choose the band of interest, how to store conversion-loss factors, and how to use the optional automatic signal-identification functions.

Operation

NOTE

Good-quality shielded SMA-type cables should be used to connect the mixer to

 

the 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.).
