Measurement Instructions (:CONFigure, :FETCh, :MEASure, :READ)
• Result will be formatted according to :FORMat[:DATA] ASCii | REAL
Query Response
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.
• Refer to the sub-section in this section titled "Descriptions of Measurement
Comments
Functions" for descriptions of each measurement function.
• Refer to Table 4-1 for a summary of the <function>, <parameters>, and
<source_list> for each of the measurement functions.
Table 4-1. The <function>, associated <parameters> and <source_list>
for the Measure Instruction Commands
<function> *
[:VOLTage]:FREQuency
[:VOLTage]:FREQuency:RATio
[:VOLTage]:MAXimum
[:VOLTage]:MINimum
[:VOLTage]:PERiod
[:VOLTage]:PTPeak
__________________________________
* The only functions which can be derived (using FETC? or READ?) from the stored data are
period to/from frequency, maximum to/from minimum, maximum to/from peak-to-peak, and
minimum to/from peak-to-peak. Ratio results require an acquisition of the ratio function.
**
<source_list> has the same syntax as SCPI <channel _list> syntax. For example, a
single-channel function (e.g., frequency, period, etc.) would use (@1) to specify channel 1,
where as a two-channel function (e.g., frequency ratio) would use (@1), (@2) to specify a
measurement between channel 1 and channel 2.
