Operation

What You’ll Learn in this Chapter

This chapter introduces you to basic preselected external-mixing functions available using

an 11974 Series Preselected Millimeter Mixer. After a brief discussion of operating

precautions and hints, operation procedures using the most commonly-used “host”

spectrum analyzers are described. This chapter contains the following topics:

• “11974Q Front-Panel Features” on page 50

• “11974Q Rear-Panel Features” on page 51

• “Operating Precautions” on page 53

“Maximum RF Input Level” on page 53

“Maximum LO Input Level” on page 53

“Electrostatic Discharge” on page 53

• “Operating Hints” on page 54

“Preventing Erroneous Preselector Peaking or Centering During Spur Searches” on

page 54

“Remote Location of an 11974” on page 55

“RF Port Voltage Standing Wave Ratio (VSWR) Effects” on page 57

“Dynamic Range Optimization” on page 57

• Preliminary Operation for Each Spectrum Analyzer

Compatibility Reference lists all compatible spectrum analyzers with the 11974

Series and defines any requirements necessary.

Equipment Connection lists all input and output connections for operation.

Frequency Tracking Calibration mates the 11974 Series to the spectrum

analyzer. This part of the preliminary operation aligns the frequency of the 11974

tracking filter to the tuned frequency of the spectrum analyzer.

NOTE Once the Frequency Tracking Calibration has been performed on a

designated setup (that is, a specific 11974 band matched to a specific

spectrum analyzer), and as long as the equipment remains connected, this

calibration procedure only needs to be performed occasionally to keep the

setup matched properly.
