Measure:vtop - Rigol DS4000E Series Programming Manual

Chapter 2 Command System
Description 2
Queries the average value, current value, standard deviation, maximum value, or minimum value of the
measurement results of the amplitude effective value (Vrms) when the measurement function of the
amplitude effective value (Vrms) 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
Amplitude effective value (Vrms): indicates the root mean square value of the waveform amplitude

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:VTOP

Syntax 1
:MEASure:VTOP [<chan>]
Description 1
Measures the amplitude top value of the specified source channel.
Syntax 2
:MEASure:VTOP? [<chan>]
Description 2
Measures and queries the amplitude top value of the specified source channel. The unit is related to the
current amplitude unit of the specified source channel.
Parameter
Name Type
<chan> Discrete
Remarks
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 measurement results in scientific notation. When the measurement results are
invalid, the query returns 9.9e37.
