Multitone Subsystem–N5172B/82B ([:SOURce]:RADio:MTONe:ARB)
Key Entry Initialize Phase Fixed Random
Remarks To change the random number generator seed value, refer to
“:SETup:TABLe:PHASe:INITialize:SEED” on page 326.
This command is the first step in creating a multitone waveform. Refer to
“Creating a Multitone Waveform” on page 311 for all four steps.
:SETup:TABLe:PHASe:INITialize:SEED
Supported N5172B/82B
[:SOURce]:RADio:MTONe:ARB:SETup:TABLe:PHASe:INITialize:SEED FIXed|RANDom
[:SOURce]:RADio:MTONe:ARB:SETup:TABLe:PHASe:INITialize:SEED?
This command initializes the random number generator seed that is used to generate the random
phase values for the multitone waveform.
FIXed This choice sets the random number generator seed to a fixed value.
RANDom This choice sets the random number generator seed to a random value. This
changes the phase value after each initialization of the phase.

Key Entry Random Seed Fixed Random
:SETup:TABLe:ROW
Supported N5172B/82B
[:SOURce]:RADio:MTONe
:ARB:SETup:TABLe:ROW <row_number>,<power>,
<phase>,<state>
[:SOURce]:RADio:MTONe:ARB:SETup:TABLe:ROW? <row_number>
This command modifies the indicated tone (row) of the multitone waveform.
<row_number> The number of rows for this variable is determined by the :SETup:TABLe
command.
<power> The power level of the tone defined in the row number. Power levels for all tones
must not exceed the power level of the signal generator. The power variable is
expressed in decibels (dB)
<phase> The phase of the tone relative to the carrier. The phase variable is expressed in
degrees.
<state> The state of the tone in this row can be enabled or disabled.
Frequency offset, power, phase, and state value are returned when a query is initiated. The output
format is as follows:
<frequency_offset>,<p
ower>,<phase>,<state>
Refer to “:SETup:TABLe” on page 324 for information on how to change the number of rows.
This command is the final step in creating a multitone waveform. Refer to “Creating a Multitone
Waveform” on page 311 for all four steps.
