Query Syntax

:ACQuire:RLENgth:MODe?

Description

Select between AUTomatic or MANual entry of samples / waveform (record length). The record length is the number of waveform samples acquired across a single sweep. Changing the samples / waveform affects sweep time (display update rate), histograms, and measurements.

AUTomatic
FlexDCA sets the record length to optimize the single record length versus total database update rate. This is the default setting and is recommended when color grade or gray scale waveform persistence, or a histogram, or a mask test is enabled.
MANual
Allows you to specify the samples / waveform from as few as 16 points using the ACQuire:RLENgth command. The default value is 2048 points.

The record length definition is locked to samples / UI this command is unavailable, if both pattern locking (:TRIGger:PLOCk) and acquire entire pattern (:ACQuire:EPATtern) is turned on.

Requires FlexDCA revision A.01.80 and above.
