348 Agilent X-Series Signal Generators SCPI Command Reference
Digital Signal Interface Module Commands
Digital Subsystem—Option 003 and 004 ([:SOURce])
:DIGital:DATA:INEGate
Supported N5172B/82B with option 003 or 004 or both
:DIGital:DATA:INEGate OFF|ON|0|1
:DIGital:DATA:INEGate?
This command enables or disables the negation of the I data sample. Negation changes the sample by
expressing it in two's complement form, multiplying by negative one, and converting back to the
selected numeric format. This can be done for I samples, Q samples, or both.
The sample or word represents a quantized analog voltage level. This analog voltage can be added or
multiplied. For a 16- bit sample, the range is from 0 to 65535 in offset binary or - 32768 to +32767 in
2’s complement mode.
Example
:DIG:DATA:INEG ON
The preceding example enables negation of the I data.

:DIGital:DATA:INPut:ATTen:AUTO
Supported N5172B/82B with option 004
:DIGital:DATA:INPut:ATTen:AUTO ON|OFF|1|0
:DIGital:DATA:INPut:ATTen:AUTO?
:DIGital:DATA:INPut:ATTen <value><unit>
:DIGital:DATA:INPut:ATTen?
This command selects Manual mode or Auto mode for the DSIM input attenuation.
When Auto mode is selected, the signal generator automatically optimizes the attenuation for the
current conditions. When the Manual mode is selected, attenuation is the active function. The value
entered sets the attenuation.
Example
:DIG:DATA:INP:ATT: 20
The preceding example sets the DSIM input attenuation to 20 dB.
*RST Auto
Range 0.00 to 50.00
