Tracking A Signal - Keysight X Series Measurement Manual

Tracking a Signal

The signal track function is useful for tracking drifting signals that drift relatively
slowly by keeping the signal centered on the display as the signal drifts. This
procedure tracks a drifting signal.
Note that the primary function of the signal track function is to track unstable
signals, not to track a signal as the center frequency of the analyzer is changed. If
you choose to use the signal track function when changing center frequency, check to
ensure that the signal found by the tracking function is the correct signal.
Step
1 Set up the signal sources.
2 Instrument setup.
3 Set the analyzer to the
Spectrum Analyzer mode.
4 Preset the analyzer.
5 Set the analyzer center
frequency, span and
reference level.
6 Place a marker on the peak
of the signal.
Action
a. Set the frequency of the signal source
to 300 MHz.
b. Set the source amplitude to
−20 dBm.
• Connect the source RF OUTPUT to the
analyzer RF INPUT as shown.
• Press Mode, Spectrum Analyzer.
• Press Mode Preset.
• Press FREQ Channel, Center
Freq, 301, MHz.
• .Press SPAN X Scale, Span, 10,
MHz.
• Press Peak Search.
