3.2 ACQuire:TYPE
Command:ACQuire:TYPE <value>:ACQuire:TYPE?
DescriptionSet or query the acquisition method of oscilloscope samples
Parameters:<value> ::= < NORMal | AVERage | PEAK | HRESolution>
State?NORMal (normal): In this mode, the oscilloscope samples the signal at equal time intervals to reconstruct the waveform. For most waveforms, using this mode produces the best display results. ?AVERages: In this mode, the oscilloscope averages waveforms that have been 18 / 136 sampled multiple times to reduce random noise on the input signal and improve vertical resolution. The number of averages can be set by the: ACQuire: AVERages command. The higher the number of averages, the lower the noise and the higher the vertical resolution, but the slower the response of the displayed waveform to waveform changes. ?PEAK (Peak Detection): In this mode, the oscilloscope collects the maximum and minimum values of the sampling interval signal to obtain the signal envelope or narrow pulses that may be lost. Using this mode can avoid aliasing of the signal, but the display noise is relatively large. ?HRESolution (high resolution): This mode uses an oversampling technique to average the neighboring points of the sampled waveform to reduce random noise on the input signal and produce a smoother waveform on the screen. It is usually used when the sampling rate of the digitizer is higher than the storage rate of the acquisition memory.
ReturnThe query returns NORM, AVERage, PEAK, or HRESolution.
Example:ACQuire:TYPE AVERage /*Set the acquisition method to average*/:ACQuire:TYPE? /*The query returns AVERage*/

4.4 TRIGger:SWEep
Command:TRIGger:SWEep <value>:TRIGger:SWEep?
DescriptionSet or query the trigger mode.
Parameters:<value> ::= < AUTO | NORMal | SINGle>
State?AUTO: Automatic triggering, waveform display regardless of whether trigger conditions are met. ?NORMal: Normal trigger, display the waveform when the trigger condition is met, keep the original waveform display when the trigger condition is not met, and wait for the next trigger. ?SINGle: Single trigger. The oscilloscope waits for the trigger, displays the waveform when the trigger conditions are met, and then stops.
ReturnThe query returns AUTO, NORMal, or SINGle.
Example:TRIGger:SWEep SINGle /*Select single trigger mode*/ :TRIGger:SWEep? /*The query returns SINGle*/
4.5 TRIGger:HOLDoff
Command:TRIGger:HOLDoff <value>:TRIGger:HOLDoff?
DescriptionSet or query the holdoff time.
Parameters:<value> ::= Trigger holdoff time (in second)
StateTrigger holdoff can stably trigger complex waveforms (such as pulse series). Holdoff time is the time the oscilloscope waits to re-enable the trigger circuit. The oscilloscope will not trigger until the holdoff time is over. When the trigger method is video trigger, timeout trigger, setup hold, UART, LIN, CAN, IIC or SPI, this setting is not available.
ReturnThe query returns the trigger holdoff time in scientific notation.
Example:TRIGger:HOLDoff 0.0000002 /*Set trigger holdoff time to 200ns*/:TRIGger:HOLDoff? /*The query returns 2.000000e-07*/
