Digital Signal Interface Module Commands
Digital Subsystem—Option 003 and 004 ([:SOURce])
*RST RNYQ
:DIGital:DATA:INPut:FILTer:CHANnel
Supported N5172B/82B with option 004
:DIGital:DATA:INPut:FILTer:CHANnel EVM|ACP
:DIGital:DATA:INPut:FILTer:CHANnel?
This command optimizes the Nyquist and root Nyquist filters to minimize error vector magnitude
(EVM) or to minimize adjacent channel power (ACP).
EVM This choice provides the most ideal passband.
ACP This choice improves stopband rejection.
Example
:DIG:DATA:INP:FILT:CHAN EVM
The preceding example selects error vector magnitude.
*RST EVM
Key Entry
Optimize FIR for EVM
:DIGital:DATA:INPut:IQ:SCALe
Supported N5172B/82B with option 004
:DIGital:DATA:INPut:IQ:SCALe <value>
:DIGital:DATA:INPut:IQ:SCALe?
This command sets the amplitude of the I/Q outputs for better adjacent channel power (ACP); lower
scaling values equate to better ACP.
The variable <value> is expressed in units of percent.
Example
:DIG:DATA:INP:IQ:SCAL 30
The preceding example sets the amplitude of the I/Q outputs to 30%.
