:ACQuire:RSPec?

Description

Selects the waveform record length to be based on Samples / Waveform or Samples / UI (Unit Interval).

RLENgth: Defines the record length as Samples / Waveform. Use the :ACQuire:RLENgth:MODE command to select automatic or manual mode. In manual mode, use ACQuire:RLENgth to enter the number of points.
SPUI: Defines the record length as Samples / UI. Use the :ACQuire:SPUI:MODE command to select automatic or manual mode. In manual mode, use ACQuire:SPUI to enter the number of points. This argument applies to FlexDCA revision A.05.60 and above.
SPBit (deprecated): Defines the record length as samples-per-bit. Use :ACQuire:SPBit:MODE to set automatic or manual mode and, if manual is selected, use ACQuire:SPBit to enter the number of samples. When writing new programs, use the SPUI argument instead.

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