DS4000E Programming Guide
Queries the average value, current value, standard deviation, maximum value, or minimum value of the
delay (falling edge-rising edge) measurement results when the delay (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 s.

Default
<chanA>
Discrete
{CHANnel1|CHANnel2|CHANnel3|CHANnel4}
--
<chanB>
Discrete
{CHANnel1|CHANnel2|CHANnel3|CHANnel4}
--
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:DSA command) and Source B (refer to the :MEASure:SETup:DSB command) of
delay 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:FPHase
Syntax 1
:MEASure:FPHase [<chanA>,<chanB>]
Description 1
Measures the phase deviation (falling edge-falling edge) between the two specified source channels.
Syntax 2
:MEASure:FPHase? [<chanA>,<chanB>]
Description 2
Measures and queries the phase deviation (falling edge-falling edge) between the two specified source
channels. The default unit is °.

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 measurement results in scientific notation. When the measurement results are invalid,
the query returns 9.9e37.
