Syntax
MEASUrement:IMMed:SOUrce<x > {CH<x>|MATH<y>|REF<x>|HIStogr am}
MEASUrement:IMMed:SOUrce<x >?
Arguments
CH<x> is an input channel waveform. The x variable can be expressed as an
integer ranging from 1 through 4.
MATH<y> is a math waveform. The y variable can be expressed as an integer
ranging from 1 through 4.
REF<X> is a reference waveform. The x variable can be expressed as an integer
ranging from 1 through 4.
HIStogram indicates histogram as the object to be measured. HIStogram not
allowed on SOUrce2.
Examples
MEASUREMENT:IMMED:SOURCE2 REF3 sets the waveform in reference memory
location 3 as the delay “to” source when making delay measurements.
MEASUREMENT:IMMED:SOURCE2? might return
:MEASUREMENT:IMMED:SOURCE2 MATH1, indicating that Math1 is the
immediate measurement source.
MEASUrement:IMMed:SOUrce<x>:SIGType
This command sets or queries the type of input signal used for measurement
SOURCE<x>, 1 or 2.
To ensure accurate measurements, use this command to specify the input-signal
type for the measurement source.
Conditions
This command is only v alid if the instrument has Option MTM is installed.

Syntax
MEASUrement:IMMed:SOUrce<x >:SIGType {PULse|EYE}
MEASUrement:IMMed:SOUrce<x >:SIGType?
Arguments
PULSE is for generic signals that are not associated with synchronous
communications standards.
EYE is for synchronous-communication signals with NRZ-like characteristics
(nonreturn to zero).
