Center Frequency
Sets the tracking generator center frequency from 250 kHz to 3 GHz in a data entry window using the
arrow keys, keypad, or tuning knob. Pressing Enter completes the change and Esc cancels the entry.
Span
Sets the total frequency window for tracking generator operation in MHz. The Span entry total is
automatically split on each side of the current center frequency.
Start Frequency
Sets the tracking generator start frequency in MHz. Use with the Stop Frequency to establish a desired
frequency range for tracking generator operation. The R8100 automatically centers the frequency display
midway between Start and Stop frequencies.
Stop Frequency
Sets the tracking generator stop frequency in MHz. Use with the Start Frequency to establish a desired
frequency range for tracking generator operation. The R8100 automatically centers the frequency display
midway between Start and Stop frequencies.
Vertical Scale
Selects the vertical scale resolution for the display’s major grid lines from 1 dB/div to 10 dB/div via a
horizontal soft key menu.
Reference Level
Adjusts the maximum level (top line) for the vertical scale of the Spectrum Analyzer in Tracking
Generator mode from -120 dBm to + 60 dBm in 1 dB increments.
# of Points
Adjusts the number of data points acquired and displayed. Higher settings increase the trace resolution
for viewing signal detail but also slow the update rate.
Display Mode
Selects the display presentation with the following horizontal menu choices:
Normal – The display updates continuously.
Freeze – Provides a snapshot of the current display indication and stops additional updates. Note: In
Freeze mode the R8100 reacquires data and updates the display whenever “Center Marker” or “Center
Peak” is pressed.
Max Hold – The display retains the highest peak signal amplitudes measured during successive sweeps.
Average – The displayed signal amplitudes are a rolling average of the peak amplitudes measured on each
successive sweep. The average consists of 1 to 5 sweeps, shown beside the mode indication.
