In this tab you can specify the waveform arithmetic for the math waveforms.
Mode
Waveform arithmetic builds the resulting waveform from several consecutive acquisi-
tions and subsequent math calculations of the signal. For details, see "Arithmetic"
on page 130.
"Original"
The original results are displayed.
"Envelope"
The envelope curve of all acquired and calculated results is dis-
played.
"Average"
The average of all acquired and calculated results is displayed.
"RMS"
The root mean square of the math data is displayed. The result is the
average power spectrum. If you measure the channel power on this
RMS spectrum, you get the same result as for the average channel
power measurement on waveforms.
"MinHold"
Determines the minimum result for each input value from the data of
the current acquisition and some acquisitions before.
"MaxHold"
Determines the maximum result for each input value from the data of
the current acquisition and some acquisitions before.

Average count (N-single count)
Access:
●
"Menu" > "Acquire" > "Setup" tab > "N-single count"
●
"Menu" > "Acquire" > "Mode"
tab > "Average count"
●
"Menu" > "Acquire" > "Segmented" tab > disable "Acquire maximum" > "Required"
●
[Math] > "Arithmetic" tab > "Mode" is not "Off" > "Average count"
The acquisition and average count has several effects:
●
It sets the number of waveforms acquired with [Single]
●
It defines the number of waveforms used to calculate the average waveform.
Thus, the instrument acquires sufficient waveforms to calculate the correct average
if "Average" is enabled for waveform arithmetic. The higher the value is, the better
the noise is reduced.
