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>.

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.

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.

MEASUrement:MEAS<x>:SOUrce<x>?

Related Commands

MEASUrement:MEAS<x>:TYPe

Arguments

CH1–4 is an analog channel to use as the source waveform.

MATH is the math waveform.

REF1–4 is a reference waveform to use as the source waveform.

D0–D15 is a digital channel 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 is the object to be measured. HIStogram only

applies to SOUrce1; it is not allowed on SOUrce2.

RF_AMPlitude|RF_FREQuency|RF_PHASe are the RF time domain traces.

(MDO4000/B/C models only.)

Examples

MEASUREMENT:MEAS4:SOURCE2 CH1 speciﬁes CH1 as the delay "to" source

when making delay measurement.

MEASUREMENT:MEAS2:SOURCE2? might return

:MEASUREMENT:MEAS2:SOURCE2 MATH1 indicating that Math 1 is the

measurement 2 source.

MEASUrement:MEAS<x>:STATE

This command speciﬁes whether the speciﬁed measurement slot is computed

and displayed. The measurement slot is speciﬁed by <x>, which ranges from

1 through 8.

For a measurement to display, you must have selected a source waveform

and deﬁned the measurement you want to take and display. You select the

measurement using the MEASUrement:MEAS<x>:SOUrce<x> command.

You deﬁne the measurement type using the MEASUrement:MEAS<x>:TYPe

command.
