Measure:pwidth - Rigol DS4000E Series Programming Manual

Chapter 2 Command System
Description 1
Measures the period amplitude effective value (Per. Vrms) of the specified source channel and enables the
statistic function of the measurement results.
Syntax 2
:MEASure:PVRMs:SAVerage? [<chan>]
:MEASure:PVRMs:SCURrent? [<chan>]
:MEASure:PVRMs:SDEViation? [<chan>]
:MEASure:PVRMs:SMAXimum? [<chan>]
:MEASure:PVRMs:SMINimum? [<chan>]
Description 2
Queries the average value, current value, standard deviation, maximum value, or minimum value of the
measurement results of the period amplitude effective value when the measurement function of the period
amplitude effective value of the specified source channel and the statistic function of the measurement
results are enabled. The unit is related to the current amplitude unit of the specified source channel.
Parameter
Name Type
<chan> Discrete
Remarks
Period amplitude effective value (Per. Vrms): indicates the amplitude root mean square value of a

single period of waveform within the current measurement range (refer to the :MEASure:AREA
command).
Before making measurements, turn on the channels to be measured.

When the math operation type is FFT (refer to the :CALCulate:MODE command), <chan> cannot be

set to "MATH".
When [<chan>] is omitted, the command, by default, applies to the currently set measurement source

(refer to the :MEASure:SOURce command).
Return Format
The query returns the average value, current value, standard deviation, maximum value, or minimum value
in scientific notation. When the measurement results are invalid, the query returns 9.9e37.

:MEASure:PWIDth

Syntax 1
:MEASure:PWIDth [<chan>]
Description 1
Measures the positive pulse width of the specified source channel.
Syntax 2
:MEASure:PWIDth? [<chan>]
Description 2
Measures and queries the positive pulse width of the specified source channel. The default unit is s.
Parameter
Name Type
<chan> Discrete
Remarks
Before making measurements, turn on the channels to be measured.
