:ACQuire Commands

Command Syntax

:ACQuire:SPUI <samples>

<samples> is a double.

Query Syntax

:ACQuire:SPUI?

Description

Enters the number of samples / UI when the following conditions are met:

If the record length is specified as Samples / Waveform using the ACQuire:RSPec command, use the ACQuire:RLENgth and ACQuire:RLENgth:MODE commands to change the Samples / UI.

This command is equivalent to the Samples / UI setting in the Waveform tab of the Acquisition Setup dialog. The time spacing between measurement points can affect interpolation between the points used to make measurements. Increasing the points increases the time required to capture a single sweep.

This sequence of commands turns on pattern lock with 64 samples per UI, acquires the entire pattern, and applies a 32-count smoothing.
