:MEASure:FALLtime

Command

:MEASure:FALLtime [<source>]

The :MEASure:FALLtime command measures the time at the upper
threshold of the falling edge, measures the time at the lower threshold of
the falling edge, then calculates the fall time. Sources are specified with
the :MEASure:SOURce command or with the optional parameter following
the :MEASure:FALLtime command.

The first displayed falling edge is used for the fall- time measurement. To
make this measurement requires 4 or more sample points on the falling
edge of the waveform.

Fall time = time at lower threshold point - time at upper threshold point.

<source>

{CHANnel<N> | FUNCtion<F> | WMEMory<N> | CLOCk | MTRend |
MSPectrum | EQUalized}

MTRend and MSPectrum sources are only available if the oscilloscope has
the EZJIT option installed and the feature is enabled.

The CLOCk source is only available if the oscilloscope has the High Speed
Serial option installed and the feature is enabled.

The EQUalized source is only available if the oscilloscope has the High
Speed Serial option and the Serial Data Equalization option installed and
the features are enabled. This command uses the Feed- Forward Equalized
(FFE) signal as the source.

<N>

CHANnel<N> is an integer, 1- 4.

WMEMory<N> is an integer, 1- 4.

<F>

FUNCtion<F> is an integer, 1- 16.

Example

This example measures the fall time of the channel 1 waveform.

myScope.WriteString ":MEASURE:FALLTIME CHANNEL1"

Query

:MEASure:FALLtime? [<source>]

The :MEASure:FALLtime? query returns the fall time of the specified
source.

Returned Format

[:MEASure:FALLtime] <value>[,<result_state>]<NL>

<value>

Time at lower threshold - time at upper threshold.

<result_state>

If SENDvalid is ON, the result state is returned with the measurement
result. See the :MEASure:RESults table in this chapter for a list of the
result states.
