SCPI Command Reference 5
:INPut:CMODe[?]
Syntax :INPut:CMODe ‘identifier’,
<SENormal|SEComplement|DIFFerential|SINGleended>
:INPut:CMODe? ‘identifier’
Input
Parameters
‘identifier’: 'M*.DataIn1', 'M*.DataIn2' or 'M*DataIn'
<SENormal|SEComplement|DIFFerential|SINGleended>: Select compare
mode.
Return Range SEN|SEC|DIFF|SING
Description This command defines the compare mode. This command defines which
input (DATA or DATA\) is active. The following options are available:
SENormal: Data stream is compared at Normal input; Complement is
terminated or connected to the complement output of the source. This
allows to measure a single-ended signal as well as the non-inverted signal
of a differential pair.
SEComplement: Data stream is compared at Complement input; Normal
is terminated or connected to the normal output of the source. This allows
to measure a single-ended signal as well as the inverted signal of a
differential pair.
DIFFerential: If differential both input ports need to receive a signal. The
actual data signal is measured as the voltage difference between the two
incoming signals.
SINGleended: Data stream is provided at either Normal input or
Complement input. The other input is either left open or terminated with
50 Ohm.
Note that the availability of the particular selection depends on the
currently used hardware.
This SCPI is applicable for M8041A, M8051A, M8061A and M8046A.
