Creating a Multitone Waveform
Use the following steps to create a multitone waveform:
1. Initialize the phase for the multitone waveform. Refer to “:SETup:TABLe:PHASe:INITialize” on
page 325.
2. Assign the frequency spacing between the tones. Refer to “:SETup:TABLe:FSPacing” on page 325.
3. Define the number of tones within the waveform. Refer to “:SETup:TABLe:NTONes” on page 325.
4. Modify the power level, phase, and state of any individual tones. Refer to “:SETup:TABLe:ROW” on
page 326.
:ALIGnment
Supported N5172B/82B
[:SOURce]:RADio:MTONe:ARB:ALIGnment LEFT|CENTer|RIGHt
[:SOURce]:RADio:MTONe:ARB:ALIGnment?
This command will align the multitones either left, center or right of the carrier frequency.
Example
:RAD:MTON:ARB:ALIG CENT
The preceding example aligns each of the multitones equidistant from the carrier frequency.

:BASEband:FREQuency:OFFSet
Supported N5172B/82B
[:SOURce]:RADio:MTONe:ARB:BASeband:FREQuency:OFFSet <val><unit>
[:SOURce]:RADio:MTONe:ARB:BASeband:FREQuency:OFFSet?
This command offsets the baseband frequency relative to the carrier. The feature is useful for moving
the signal such that the carrier feed–through is not in the center.
The X- Series signal generator provides automatic DAC over–range protection when the offset value is
something other than 0 Hz. It scales down the playing I/Q data by 1/square root of 2.
*RST 0.000
Range +5.0E7 to –5.0E7 Hz

:BASeband:FREQuency:OFFSet:PHASe:RESet
Supported N5172B/82B
[:SOURce]:RADio:MTONe:ARB:BASeband:FREQuency:OFFSet:PHASe:RESet
This command clears the phase accumulation and so zero phase shift.
