Acquire Commands

AVERage

Acquire Commands

The ACQuire subsystem commands set up conditions for acquiring waveform data, including

the DIGitize root level command. The commands in this subsystem select the number of aver-

ages and the number of data points. This subsystem also includes commands to set limits on

how much data is acquired, and specify actions to execute when acquisition limits are met.

AVERage

Command :ACQuire:AVERage {{ON | 1} | {OFF | 0}}

This command enables or disables averaging. When ON, the analyzer acquires multiple data

values for each time bucket, and averages them. When OFF, averaging is disabled. To set the

number of averages, use the :ACQuire:COUNt command described later in this chapter.

NOTE Do not use this command in Jitter Mode. It generates a “Settings conflict” error.Query

Query :ACQuire:AVERage?

Returned Format [:ACQuire:AVERage] {1 | 0}<NL>

Example 10 OUTPUT 707;":ACQUIRE:AVERAGE ON"

BEST

Command :ACQuire:BEST {THRuput | FLATness}

When averaging is enabled with ACQuire:AVERage, the FLATness option improves the step

flatness by using a signal processing algorithm within the instrument. You should use this

option when performing TDR measurements or when step flatness is important. The THRu-

put option improves the instrument’s throughput and should be used whenever best flatness

is not required.

NOTE Do not use this command in Jitter Mode. It generates a “Settings conflict” error.

Query :ACQuire:BEST?

Returned Format [:ACQuire:BEST] {THRuput | FLATness}<NL>

Example 10 OUTPUT 707;":ACQUIRE:BEST FLATNESS"

COUNt

Command :ACQuire:COUNt <value>

This command sets the number of averages for the waveforms. In the AVERage mode, the

ACQuire:COUNt command specifies the number of data values to be averaged for each time

bucket before the acquisition is considered complete for that time bucket. <value> is an inte-

ger, 1 to 4096, specifying the number of data values to be averaged.
