Keysight M8070A Programming Guide 239
SCPI Command Reference 5
Return Range -1.0 V to 2.6 V; The range is dependent on other system parameters. See
Command Syntax to Find Min/Max Values on page 108.
Description This command is used to measure the common mode voltage of the
selected data input by the module itself. Acceptable units are mV, V and
exponents (for example, 300E-3 is the same as 300 mV).
This SCPI is applicable for M8041A and M8051A.
Example :INP:CMV ‘M1.DataIn1’, 300mV
:INPut:CMVoltage:DETect
Syntax :INPut:CMVoltage:DETect
‘identifier’
Input
Parameters
‘identifier’: 'M*.DataIn1' or 'M*.DataIn2'
Description This command measures the common mode voltage at the selected data
input and applies it to the comparator.
This SCPI is applicable for M8041A and M8051A.
Example :INP:CMV:DET ‘M1.DataIn1’
:INPut:THReshold[?]
Syntax :INPut:THReshold ‘identifier’, <NRf>
:INPut:THReshold? ‘identifier’
Input
Parameters
‘identifier’: 'M*.DataIn1', 'M*.DataIn2', 'M2.ElectIdleIn', or 'M*DataIn'
<NRf>: Set receiver input threshold voltage.
Return Range For M8041A and M8051A: -1 V to 1 V
For M8062A: -800 mV to 800 mV
For M8046A: -250 mV to 250 mV
Description This command sets the threshold voltage of the selected receiver input
connector (decision threshold). Acceptable units are mV, V and exponents
(for example, 300E-3 is the same as 300 mV).
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
Example :INP:THR ‘M1.DataIn1’, 200 mV
