of averaging, w
here the average comes from a single waveform acquisition. The
number of samples taken during the acquisition interval determines the number of
data values that compose the average.
AVErage specifies averaging mode, in which the resulting waveform shows an
average of SAMple data points from several separate waveform acquisitions. The
oscilloscope processes the number of waveforms you specify into the acquired
waveform, creating a running exponential average of the input signal. The number
of waveform acquisitions that go into making up the average waveform is set or
queried using the ACQuire:NUMAVg command.
ENVelope specifies envelope mode, where th e resulting waveform shows the
PEAKdetect range of data points from every waveform a cquisition.
Examples
ACQUIRE:MODE ENVELOPE sets the acquisition mode to display a waveform that
is an envelope of many individual waveform acquisitions.
ACQUIRE:MODE? might return:ACQuire:MODe AVERAGE indicating that
the displayed waveform is the average of the specified number of waveform
acquisitions.
ACQuire:NUMACq? (Query Only)
Returns the number of waveform acquisitions that have occurred since starting
acquisition with the ACQ uire :STATE:RUN command. This value is reset to zero
when any acquisition, horizontal, or vertical arguments that affect the waveform
are changed. The maximum number of acquisitions that can be counted is 2

Returns
ACQuire:NUMACq? might return :ACQUIRE:N UMACQ 350 indicat
ing that 350
acquisitions have occurred since executing an A CQuire:STATE RUN command.
ACQuire:NUMAVg
Sets or returns the number of waveform acquisitions that make up an averaged
waveform. Use the ACQuire:MODe command to enable the Average mode.
Sending this command is equivalent to turning a multipurpose knob to enter the
number of waveform acquisitions to average.
