"Spectrum"
The current value for each frequency is displayed.
"Min Hold"
The minimum value for each frequency over all FFTs is displayed.
Using the "Min Hold" waveform type is a good way to highlight signals
within noise or suppress intermittent signals.
"Max Hold"
The maximum value for each frequency over all FFTs is displayed.
Using the "Max Hold" waveform type is a good way to detect intermit-
tent signals or the maximum values of fluctuating signals, for exam-
ple.
"Average"
The average value for each frequency in the waveform over the
specified "# Averages" is calculated.
Averaging reduces the effects of noise, but has no effects on sine sig-
nals. Therefore, averaging is a good way to detect signals near noise.
"Reset"
Clears the selected waveforms and restarts calculation.

Vertical Scale
Defines the scaling unit for the vertical scale.
The displayed values refer to a 50 Ohm terminating resistor. You can use an external
terminating resistor parallel to the high impedance input, or the 50 Ohm input directly.
"dBm"
Logarithmic scaling; related to 1 mW
