Command Syntax

:ACQuire:TYPE <type>

<type> ::= {NORMal AVERage HRESolution PEAK}

The :ACQuire:TYPE command selects the type of data acquisition that is to take place. The acquisition types are: NORMal, AVERage, HRESolution, and PEAK.

The :ACQuire:TYPE NORMal command sets the oscilloscope in the normal mode.

The :ACQuire:TYPE AVERage command sets the oscilloscope in the averaging mode. You can set the count by sending the :ACQuire:COUNt command followed by the number of averages. In this mode, the value for averages is an integer from 1 (smoothing) to 65536. The COUNt value determines the number of averages that must be acquired.

The :ACQuire:TYPE HRESolution command sets the oscilloscope in the high- resolution mode (also known as smoothing). This mode is used to reduce noise at slower sweep speeds where the digitizer samples faster than needed to fill memory for the displayed time range.

For example, if the digitizer samples at 200 MSa/s, but the effective sample rate is 1 MSa/s (because of a slower sweep speed), only 1 out of every 200 samples needs to be stored. Instead of storing one sample (and throwing others away), the 200 samples are averaged together to provide the value for one display point. The slower the sweep speed, the greater the number of samples that are averaged together for each display point.

This command is functionally equivalent to :ACQuire:TYPE AVERage and :ACQuire:COUNt 1.

The :ACQuire:TYPE PEAK command sets the oscilloscope in the peak detect mode. In this mode, :ACQuire:COUNt has no meaning.

The obsolete command ACQuire:TYPE:REALtime is functionally equivalent to sending ACQuire:MODE RTIME; TYPE NORMal.
