Making Measurements
Example 8: External Millimeter Mixers (Unpreselected)
Example 8: External Millimeter Mixers
(Unpreselected)
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.) Agilent Technologies manufactures external mixers that do
not require biasing and cover frequency ranges from 18 GHz to 110
GHz. Other manufacturers sell mixers that extend the range to 325
GHz, but may require biasing. The 8560 E-Series and EC-Series
spectrum analyzers support both types of mixers.
Spectrum Analyzer Functions Used
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.
Stepping through the Measurement
Set up the equipment
1. Figure 2-44 illustrates how to connect an external harmonic mixer to
the spectrum analyzer.
CAUTION The spectrum analyzer local-oscillator output power is +16.5 dBm. Be
sure that your external harmonic mixer can accommodate this power
level before connecting it to the analyzer.
