Arb Commands
Dmodulation Subsystem–N5172B/82B with Option 431 ([:SOURce]:RADio:DMODulation:ARB)
This command sets the modulation type for the digital modulation personality.
*RST
QPSK
:MODulation:UFSK
Supported
N5172B/82B with Option 431
[:SOURce]:RADio:DMODulation:ARB:MODulation:UFSK <“filename”>
[:SOURce]:RADio:DMODulation:ARB:MODulation:UFSK?
This command selects the user FSK file to use when the
:MODulation[:TYPE]
is set to UFSK.
For more information on the file name syntax, see
“File Name Variables” on page 13
.
Key Entry
Select User FSK
:MODulation:UIQ
Supported
N5172B/82B with Option 431
[:SOURce]:RADio:DMODulation:ARB:MODulation:UIQ <“filename”>
[:SOURce]:RADio:DMODulation:ARB:MODulation:UIQ?
This command selects the user FSK file to use when the
:MODulation[:TYPE]
is set to UIQ.
For more information on the file name syntax, see
“File Name Variables” on page 13
.
Key Entry
Select User I/Q
:MODulation:UQPSk[:GAIN]
Supported
N5172B/82B with Option 431
[:SOURce]:RADio:DMODulation:ARB:MODulation:UQPSk[:GAIN] <val>
[:SOURce]:RADio:DMODulation:ARB:MODulation:UQPSk[:GAIN]?
This command sets the Unbalanced QPSK modulation I versus Q gain, which is the difference in
amplitude between I and Q. UQPSK is a 2 bits per symbol modulation where the I constellation
values are typically set to be larger or smaller than the Q constellation values. This factor is known
as the I Gain. Use this command when the
:MODulation[:TYPE]
is set to UQPSk.
The variable <val> is expressed in units of dB and the resolution is 0.01 dB.
