ACQuire:TYPE
Syntax :ACQuire:TYPE <value>
:ACQuire:TYPE?
Description :Set or query the acquisition mode of the oscilloscope
Parameter :<value> ::= < NORMal | AVERage | PEAK | HRESolution>
Explanation : NORMal: in this mode, the oscilloscope samples the signal at equal time
interval to rebuild the waveform. For most of the waveforms, the best
display effect can be obtained using this mode.
: AVERage: in this mode, the oscilloscope averages the waveforms from
multiple samples to reduce the random noise of the input signal and
improve the vertical resolution. Greater number of averages can lower the
noise and increase the vertical resolution,but will also slow the response of
the displayed waveform to the waveform changes.
: PEAK: in this mode, the oscilloscope acquires the maximum and minimum
values of the signal within the sample interval to get the envelope of the
signal or the narrow pulse of the signal that might be lost. In this mode,
signal confusion can be prevented but the noise displayed would be larger.
: HRESolution: this mode uses a kind of ultra-sample technique to
average the neighboring points of the sample waveform to reduce the
random noise on the input signal and generate much smoother waveforms
on the screen. This is generally used when the sample rate of the digital
converter is higher than the storage rate of the acquisition memory.
Return :The query returns NORMal，AVERage，PEAK，HRESolution
Example :ACQuire:TYPE /*Select the average acquisition mode
AVERage*/
:ACQuire:TYPE? /* The query returns AVERage */
ACQuire:SRATe?
Syntax :ACQuire:SRATe?
Description : Query the current sample rate
Explanation : Sample rate is the sample frequency of the oscilloscope, namely the
waveform points sampled per second
Return :The query returns the actual number of points
Example :ACQuire:SRATe? /* The query returns 1.25e+06*/
