274 Agilent X-Series Signal Generators SCPI Command Reference
Arb Commands
Dual ARB Subsystem–N5172B/82B ([:SOURce]:RADio:ARB)
IORQ This choice clips I and Q separately. When this choice is enabled, percentage
values for both I and Q must be specified.
Range <value>: 10–100 (0.1% resolution)
Remarks A value of 100 percent equates to no clipping.
For information on the file name syntax, refer to “File Name Variables” on
page 13.
:DOPRotection
Supported N5172B/82B
[:SOURce]:RADio:ARB:DOPRotection ON|OFF|1|0
[:SOURce]:RADio:ARB:DOPRotection?
This commands turns the DAC over–range protection feature off or on.
The over–range protection feature works only with the Baseband Frequency Offset feature and the
Option 432 Phase Noise Impairment.
On Minimizes the occurrence of a DAC over–range condition. In doing so, it can also
decrease the dynamic range of the waveform by scaling the data more than what
is actually needed. For the Baseband Frequency Offset feature, this protection is
active only when the offset parameter is a value other than 0 Hz.
Off The automatic protection feature is not enabled. To correct a DAC over–range
condition, reduce the waveform runtime scaling value (see “:RSCaling” on
page 298).
*RST ON
Key Entry DAC Over–range Protection Off On
:FILTer:ALPHa
Supported N5172B/82B
[:SOURce]:RADio[1]:ARB:FILTer:ALPHa <value>
[:SOURce]:RADio[1]:ARB:FILTer:ALPHa?
This command changes the Nyquist or Root Nyquist Real- Time Modulation filter alpha value.
The filter alpha value can be set to the minimum level (0), the maximum level (1), or in between by
using fractional numeric values (0.001 to 0.999).
*RST +3.50000000E001
Range 0.000 to 1.000
Key Entry Filter Alpha
Remarks To change the current filter type, refer to :FILTer:TYPE.
*RST IJQ <value>: +100
Key Entry Clipping Type |I+jQ| |I|,|Q|
