Commands Listed in Alphabetical Order
Examples
MEASUREMENT:I
NDICATORS:STATE MEAS2
turns on the display of visible
measurement indicators for measurement 2.
MEASUREMENT:
INDICATORS:STATE?
might return
MEASUREMENT:INDICATORS:STATE OFF indicating that no measurement
indicators are active.
MEASUremen
t:INDICators:VERT<x>? (Query Only)
Returns the value of the specified vertical measurement indicator <x> from the
trigger point, where <x> can be 1 through 8. A negative value means that the
indicato
r is positioned earlier in the waveform record than the trigger point.

Syntax
MEASUrement:INDICators:VERT<x>?
Examples
MEASUREMENT:INDICATORS:VERT2? might return
MEASUREMENT:INDICATORS:VERT2 -3.724507E-6 indicating that the
second measurement indicator is positioned 3.72 μs before the trigger point.
MEASUrement:MEAS<x>? (Query Only)
Returns all measurement parameters
for the specified active measurement <x>.
Group
Measurement
Syntax
MEASUrement:MEAS<x>?
MEASUrement:MEAS<x>:COUNt? (Query O nly)
Returns the number of values accumulated for this measurement since the last
statistical reset. Values may be ignored if they generated an error. Measurements
are specified by x, which ranges from 1 through 8.

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.
Group
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.
