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.

Measurement
Syntax
MEASUrement:MEAS<x>:MEAN?
Examples
MEASUREMENT:MEAS1:MEAN? might return :MEASUREMENT:MEAS1:MEAN
514.71E-09.
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.
Group
Measurement
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.

MEASUrement:
MEAS<x>:SOUrce<x>,
MEASUrement:MEAS<x>:TYPe
Arguments
OFF disables calculation and display of the specified measurement slot.
ON enables calculation and display of the specified measurement slot.
<NR1> = 0 disables calculation and display of the specified measurement slot; any
other value enables calculation and display of the specified measurement slot.
Examples
MEASUREMENT:MEAS2:STATE ON computes and displays the measurement
defined as measurement 2.
MEASUREMENT:MEAS1:STATE? might return :MEASUREMENT:MEAS1:STATE 0
indicating that measurement defined for measurement slot 1 is disabled.
MEASUrement:MEAS<x>:STDdev? (Query Only)
Returns the standard deviation of values accumulated for this measurementsince
the last statistical reset. Measurements are specified by <x>, the measurement
slots, from 1 through 8.

Syntax
MEASUrement:MEAS<x>:STDdev?
Examples
MEASUREMENT:MEAS1:STDDEV? might return :MEASUREMENT:ME AS1:STDDEV

MEASUrement:MEAS<x>:TYPe
This command specifies the measurement type defined for the specified
measurement slot. The measurement slotisspecifiedby<x>,whichrangesfrom
1 through 8 in all models except MDO3000, which only support 4 simultaneous
measurements.
Digital channel measurements do not have a user-settable midRef threshold. If
you specify a digital channel measurement that is not available, measurement
error 2200: measurement system error occurs and 9.9e37 is returned.
