Measure:frequency - 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
phase deviation (falling edge-rising edge) measurement results when the phase deviation (falling
edge-rising edge) measurement function between the two specified source channels and the statistic
function of the measurement results are enabled. The default unit is °.
Parameter
Name Type
<chanA> Discrete
<chanB> Discrete
Remarks
Before making measurements, turn on the channels to be measured.

When [<chanA>,<chanB>] is omitted, this command will be applied to Source A (refer to

the :MEASure:SETup:PSA command) and Source B (refer to the :MEASure:SETup:PSB command) of
phase measurement currently set by default.
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:FREQuency

Syntax 1
:MEASure:FREQuency [<chan>]
Description 1
Measures the frequency of the specified source channel.
Syntax 2
:MEASure:FREQuency? [<chan>]
Description 2
Measures and queries the frequency of the specified source channel. The default unit is Hz.
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.
