Chapter 2 — E-Series Tracking
Generator
(Option 20)
2-1 Generator Mode
Option 20 adds a Tracking Generator to the Spectrum Analyzer mode of the instrument. The
Tracking Generator generates a swept signal with an output frequency that is the same as
the tuning frequency of the spectrum analyzer.
Additionally, a CW generator feature is included in Option 20. The sine wave output
frequency and power is set by the user. Refer to
Section 2-5 “CW Generator Overview”
on page 2-8 .
The output power is leveled and has a specified power range –50 dBm to +0 dBm in
0.1 dB steps.
Power output information is available for both absolute and transmission (normalized)
measurements.
Enhanced power level calibration is available for the generator output. Additional
information about the enhanced level calibration is provided later in this chapter.

6. Set the
Generator Mode
to
Tracking
. In Tracking Mode, the output frequency is paired
with the spectrum analyzer input sweeping frequency.
7. Turn
Generator Output On
. The output power turns on at the level that has been set
previously with the
