Tracking Generator MG PN: 10580-00339 Rev. C 3-1
Chapter 3 — T-Series Tracking
Generator
(Option 809, Option 813, and Option 820)
3-1 Generator Mode
Options 809, 813, and 820 add 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 these options. The sine wave output
frequency and power is set by the user. Refer to
Section 3-5 “CW Generator Overview”
on page 3-6 .
The output power is leveled and has a specified power range from –40 dBm to +0 dBm in
0.1 dB steps.
Power output information is available for both absolute and transmission (normalized)
measurements.
3-2 Tracking Generator Overview
1. Set the
Mode
to
Spectrum Analyzer.
Refer to Chapter 1 for details.
2.
Preset
the instrument
(Shift+1 > Preset
).
3. Set the spectrum analyzer frequency range using the Frequency (
Freq)
menu and
submenus. Refer to the Spectrum Analyzer Measurement Guide (10580-00349) for
additional information.
4. Press the
Shift
key, then the
Measure
(
4
) key. Press the
Generator
key.
5. Press the
Output Power
button and set the output power (at the output connector before
any external attenuation). In tracking mode, the output is leveled and flat over the
spectrum analyzer frequency range.
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
Output Power
key.
Note
Operation outside this power range is possible. However, performance and
compliance with specifications are not guaranteed.
Note
Turning the Tracking Generator On sets the detection type ( Amplitude > Detection)
to Sample and sets the sweep mode ( Sweep > Sweep Mode) to No FFT. Turning
off the generator resets both parameters to their previous settings. Either parameter
may be changed by the user with the Tracking Generator on or by the instrument
when other measurements are also turned on.
