Input Type:
Selects a single or dual input spectrum.
Input #1:
Input Select #1 determines the input source used for all single spectrums and channel #1 of dual spectrums.
Input #2:
Input Select #2 determines the input source for channel #2 of dual spectrums.
Display Mode:
The Display Mode affects how the spectrum data is presented, in Realtime mode the spectrum is updated with new data each time, Peak
Hold displays the highest value in the last Hold Count value of spectrums, Average displays the average of the last Average Count of spectrums, and
Infinite holds the highest values until reset.
Hold Count:
Determines how many spectrums are used to compute the maximum values at each data point when the Display Mode = Peak Hold.
Avg Count:
Sets how many spectrum are used to compute the spectrum average when the Display Mode = Average.
0dB Ref Lev:
The 0dB Reference Level normalizes the 0dB point on the spectrum display to a specific dB value.
Curve Fill:
Determines whether the spectrum display is a signal line or filled in from the bottom up.
Colors:
Changes the normally green spectrum display into a multi-color display.
Measurements:
Enables any additional measurements associated with the spectrum.

Time Mode:
The Time Mode affects all the peak modulation readings and bar graphs. In Real Time Mode when a peak exceeds the current displayed
peak the value is updated immediately to the new value and held for the Hold Time, until either a new peak is detected or the Hold Time is met. In Past
Time Mode, the unit waits the Hold Time and displays the highest peak which was detected during that time period.
Hold Time:
Adjusts the Peak Hold Time from 0.25 to 0.5 - 5.0 seconds in 0.5 second increments.
Infinite:
When Infinite Hold is enabled, the highest peak values are held until disabled. Infinite Hold affects all the modulation readings and bar graphs.
Units:
The units for modulation data may be displayed in either% where 100% = 75 kHz deviation, or directly in kHz deviation.
De-Emphasis:
Sets the De-Emphasis for all de-emphasized readings to either 50 µsec or 75 µsec.
Filter Response:
Selects the Left, Right, L+R, and L-R frequency response. The normal setting uses the standard 15 kHz bandwidth for readings and
audio outputs. The extended option increases the filter bandwidth to 16.5 KHz. Extending the filter response can result in more accurate L, R, L+R, and
L-R peak modulation readings. This is dependent on the audio programming and processor settings.
Remote:
Allows or blocks remote connections to the unit via the RS-232 or RJ-45 connector.
Screen Saver:
The Screen Saver turns off the LCD’s backlight after a specified period without any encoder activity. The choices are off, and 1 to 12
hours in 1 hour increments.
Reset Defaults:
To reset the unit back to factory defaults click on the Reset Defaults Button.
Reboot:
To reboot the unit click on the Reboot Button.
