MEASUrement:I
NDICators:NUMHORZ?
Examples
MEASUREMENT:INDICATORS:NUMHORZ? might return
MEASUREMENT:INDICATORS:NUMHORZ 2 indicating there are currently
2 horizontal lines drawn on the graticule. The indicators show where the
measurement specified by MEASUrement:INDICators:STATE is being
performed.
MEASUrement:INDICators:NUMVERT? (Query Only)
Returns the number of vertical measurement indicators currently being displayed.

MEASUrement:INDICators:NUMVERT?
Examples
MEASUREMENT:INDICATORS:NUMVERT? might return
MEASUREMENT:INDICATORS:NUMVERT 2 indicating there are currently 2
vertical lines drawn on the graticule. The indicators show where the measurement
specified by MEASUrement:INDICators:STATE is being performed.
MEASUrement:INDICators:STATE
This command specifies the state of visible measurement indicators.
Group
Measurement
Syntax
MEASUrement:INDICators:STATE {OFF|MEAS<x>}
MEASUrement:INDICators:STATE?
Arguments
OFF turns the visible measurement indicators off.
MEAS<x> displays the visible measurement indicators for measurement <x>,
where <x> can be 1 through 8.
NOTE. Theremustbeanactivemeasurementbefore you can activate an indicator
for a specified measurement.

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.
Group
Measurement
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.

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.

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.
