Examples
MEASUREMENT:M
EAS3:COUNT?
might return :MEASUREMENT:MEAS3:COUNT
3247.
MEASUrement:MEAS<x>:DELay? (Query Only)
Returns the delay measurement parameters for the measurement specified by
<x>, which ranges from 1 through 8.

Measurement
Syntax
MEASUrement:MEAS<x>:DELay?
Examples
MEASUREMENT:MEAS1? might return
:MEASUREMENT:MEAS1:DELAY:DIRECTION FORWARDS;EDGE1 RISE;EDGE2
RISE
.
MEASUrement:MEAS<x>:DELay:DIRection
This command specifies the starting point and direction that determines
the delay "to" edge when taking a delay measurement. Use the
MEASUrement:MEAS<x>:SOUrce<x> command to specify the waveform.
Group
Measurement
Syntax
MEASUrement:MEAS<x>:DELay:DIRection {BACKWards|FORWards}
MEASUrement:MEAS<x>:DELay:DIRection?
Related Commands
MEASUrement:MEAS<x>:SOUrce<x>
Arguments
BACKWards means the search starts at the end of the waveform and
looks for the last rising or falling edge in the waveform. Use the
MEASUrement:MEAS<x>:DELay:EDGE<x> command to specify the slope
of the edge.
FORWards means the search starts at the beginning of the waveform
and looks for the first rising or falling edge in the waveform. Use the
MEASUrement:MEAS<x>:DELay:EDGE<x> command to specify the slope
of the edge.

Examples
MEASUREMENT:M
EAS3:DELAY:DIRECTION BACKWARDS
starts searching from
the end of the waveform record.
MEASUREMENT:
MEAS3:DELAY:DIRECTION?
might return
:MEASUREMENT:MEAS3:DELAY:DIRECTION BACKWARDS indicating
that the current search direction is backwards.
MEASUremen
t:MEAS<x>:DELay:EDGE<x>
This command specifies the slope of the edge used for the delay "from" or "to"
waveform when taking an immediate delay measurement. The waveform is
specified
by MEASUrement:MEAS<x>:SOUrce<x>.
Group
Measurement
Syntax
MEASUrement:MEAS<x>:DELay:EDGE<x> {FALL|RISe}
MEASUrement:MEAS<x>:DELay:EDGE<x>?
Arguments
<x> specifies which waveform to use, where <x> = 1 is the "from" waveform, and
<x> = 2 is the "to" waveform.
FALL specifies the falling edge.
RISe specifies the rising edge.
Examples
MEASUREMENT:MEAS1:DELAY:EDGE1 RISE specifies that the "from" waveform
rising edge be used for the immediate delay measurement.
MEASUREMENT:MEAS1:DELAY:EDGE1? returns either RISE or FALL.
MEASUrement:MEAS<x>:MAXimum? (Query Only)
Returns the maximum value found for this measurement since the last statistical
reset. Measurements are specified by x, which ranges from 1 through 8.
Group
Measurement
Syntax
MEASUrement:MEAS<x>:MAXimum?
Examples
MEASUREMENT:MEAS3:MAXIMUM? might return
:MEASUREMENT:MEAS3:MAXIMUM 4.18E-9.

MEASUrement:
MEAS<x>:MEAN? (Query Only)
Returns the mean value accumulated for this measurement since the last statistical
reset. Measurements are specified by x, which ranges from 1 through 8.

Examples
MEASUREMENT:MEAS1:MEAN? might return :MEASUREMENT:MEAS1:MEAN

MEASUrement:MEAS<x>:MINImum? (Query Only)
Returns the minimum value for this measurement since the last statistical reset.
Measurements are specified by <x>, which ranges from 1 through 8.

Syntax
MEASUrement:MEAS<x>:MINImum?
Examples
MEASUREMENT:MEAS1:MINIMUM? might return
:MEASUREMENT:MEAS1:MINIMUM 1.75E-09.
MEASUrement:MEAS<x>:SOUrce<x>
For SOURce1: This command specifies the source for all single channel
measurements. For delay or phase measurements, This command specifies the
waveform to measure "from". This is equiv
alent to setting the "From:" waveform
in the "Measure Delay" side menu or the "Measure Phase" side menu. SOUrce is
equivalent to SOURCE1.
For SOUrce2: This command specifies the waveform to measure "to" when taking
a delay measurement or phase measurement. This is equivalent to setting the"To:"
waveform in the "Measure Delay" side menu or the "Measure Phase" side menu.
Measurements are specified by <x>, which ranges from 1 to 8.
NOTE. If you do not specify a numeric suffix,thesourceisassumedtobeSOUrce1.
