Introduction

:CALCulate[1] Subsystem

Performs post-acquisition math (scale/offset) processing (on the data acquired by a SENSe function) and data transfer of the scaled/offset result. See the :TRACe subsystem for commands used to set the scale and offset.

Not until :CALCulate[1]:MATH:STATe is set to ON will any of the :CALCulate[1] settings or :TRACe[:DATA] settings be used.

:CALCulate[1]:DATA?

Queries the current scaled and offset measurement result .

Query Response ∙ Result will be formatted according to :FORMat[:DATA] ASCii REAL setting.

When ASCii format is used, numeric data is transferred as ASCII bytes in <NR3> format. The number of significant digits will range from 1 to 15, depending on the measurement resolution. Only significant digits will be returned.

If no valid result exists, Not a Number 9.91E37 is returned and error -230 is generated.

If the current measurement is Totalize or Voltage Peaks, Not a Number 9.91E37 is returned and error -221 is generated.

Comments ∙ Query only.

If this command is issued when math is enabled and while a measurement is in progress, no response will be produced until the measurement completes.

This command holds off subsequent commands from being processed until a measurement completes. This holdoff action can only be canceled by the measurement completing, a device clear, or power cycle.

The last calculated result remains valid until a new computation is made or a relevant instrument state is modified.
