MEASUREMENT:G
ATING?
might return :MEASUREMENT:GATING CURSOR
indicating that measurements are limited to the portion of the waveform between
the vertical bar cursors.
MEASUrement
:IMMed? (Query Only)
Returns all immediate measurement setup parameters.

Syntax
MEASUrement:IMMed?
Examples
MEASUREMENT:IMMED? might return
:MEASUREMENT:IMMED:DELAY:DIRECTION FORWARDS;EDGE1 RISE;EDGE2
RISE;:MEASUREMENT:IMMED:TYPE PERIOD;UNITS "s";SOUR CE1
CH1;SOURCE2 CH2
MEASUrement:IMMed:DELay? (Query Only)
Returns information about the immediate delay measurement. This command is
equivalent to viewing the delay measurement settings on the measurement readout.

Syntax
MEASUrement:IMMed:DELay?
Examples
MEASUREMENT:IMMED:DELAY? might return
:MEASUREMENT:IMMED:DELAY:DIRECTION FORWARDS; EDGE1
RISE;EDGE2 RISE
MEASUrement:IMMed:DELay:DIRection
This command specifies the starting point and direction that determines the delay
"to" edge when taking an immediate delay measurement.
NOTE. Use the MEASUrement:IMMed:SOUrce<x> command to specify the
delay "to" waveform.

Syntax
MEASUrement:IMMed:DELay:DIRection {BACKWards|FORWards}
MEASUrement:IMMed:DELay:DIRection?
Related Commands
MEASUrement:IMMed:SOUrce<x>
Arguments
BACKWards starts the search at the end of the waveform and looks for the last
rising or falling edge in the waveform.
FORWards starts the search at the beginning of the waveform and looks for the
first rising or falling edge in the waveform.
Examples
MEASUREMENT:IMMED:DELAY:DIRECTION FORWARDS starts searching from the
beginning of the waveform record and looks for the first rising or falling edge.
MEASUREMENT:IMMED:DELAY:DIRECTION? might return
:MEASUREMENT:IMMED:DELAY:DIRECTION BACKWARDS indicating
that searching begins at the end of the waveform record and looks for the last
rising or falling edge.
MEASUrement:IMMed:DELay:EDGE<x>
This command specifies the slope of the edge the oscilloscope uses for the delay
"from" or "to" waveform when taking an immediate delay measurement.

Syntax
MEASUrement:IMMed:DELay:EDGE<x> {FALL|RISe}
MEASUrement:IMMed:DELay:EDGE<x>?
Related Commands
MEASUrement:IMMed:SOUrce<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:I
MMED:DELAY:EDGE1 RISE
specifies that the "from" waveform
rising edge be used for the immediate delay measurement.
MEASUREMENT:
IMMED:DELAY:EDGE1?
returns either RISE or FALL.
MEASUrement:IMMed: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 equivalent to setting the "From:" waveform
in the "Measure Delay" side menu or the "Measure Phase" side menu. SOUrce is
equivale
nt to SOURCE1.
For SOUrce2: This command specifies the waveform to measure "to" when taking
adelaym
easurement or phase measurement. This is equivalent to setting the "To:"
waveform in the "Measure Delay" side menu or the "Measure Phase" side menu.
NOTE. If you do not specify a numerical suffix,thesourceisassumedtobe
SOUrce1.

|D11|D12|D13|D14|D15|HIStogram|RF_AMPlitude|RF_FREQuency|RF_ PHASe}
MEASUrement:IMMed:SOUrce<x>?
Arguments
CH1–CH4 is the analog channel to use as the source waveform.
MATH is the math waveform.
D0 — D15 is the digital waveform to use as the source waveform.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
HIStogram indicates the histogram as the object to be measured. HIStogram only
applies to SOUrce1; it is not available for SOUrce2.
RF_AMPlitude|RF_FREQuency|RF_PHASe are the RF time domain traces.
(MDO4000/B/C only.)
MEASUrement:IMMed:TYPe
This command specifies the immediate measurement type.
