24 Measure Commands
:MEASure:HISTogram:STDDev
Command :MEASure:HISTogram:STDDev [<source>]
The :MEASure:HISTogram:STDDev command places the histogram standard
deviation measurement into the Measurements tab of the oscilloscope's
user interface.
The source is specified with the :MEASure:SOURce command or with the
optional parameter following the command.
The :MEASure:HISTogram commands only apply to Meas Histogram math
functions, the histogram waveform, or memories containing histograms.
<source> { FUNCtion<N> | WMEMory<N> | HISTogram}
<N> An integer, 1 - 4.
Example This example places into the Measurements tab the standard deviation of
the histogram stored in WMEMory1.
myScope.WriteString ":MEASure:HISTogram:STDDev WMEMory1"
Query :MEASure:HISTogram:STDDev? [<source>]
The :MEASure:HISTogram:STDDev? query returns the measurement of
standard deviation of the histogram.
Returned Format
[:MEASure:HISTogram:STDDev]<value>[,<result_state>]<NL>
<value> The standard deviation of the histogram.
<result_state> If SENDVALID is ON, the result state is returned with the measurement
result. Refer to the MEASure:RESults command, for a list of the result
states.
Example This example returns the standard deviation of the histogram whose
source is specified using the MEASure:SOURce command and prints the
result to the computer's screen.
myScope.WriteString ":SYSTem:HEADer OFF" ' Response headers off.
myScope.WriteString ":MEASure:HISTogram:STDDEV? WMEMory1"
varHiststtd = myScope.ReadNumber
Debug.Print FormatNumber(varHiststtd, 0)
