Two Tone Subsystem–N5172B/82B ([:SOURce]:RADio:TTONe:ARB)
This query returns the theoretical phase noise amplitude mask applied with the current settings if
the phase noise feature is on. This mask does not take the natural phase noise of the instrument into
account, only the impairment from the phase noise feature. The output is over the start frequency to
the stop frequency for the number of samples specified. The samples are taken at logarithmic
frequency steps and the output is in dBc/Hz.
:SCLock:RATE
Supported N5172B/82B
[:SOURce]:RADio:TTONe:ARB:SCLock:RATE <sample_clock_rate>
[:SOURce]:RADio:TTONE:ARB:SCLock:RATE?
This command sets the ARB sample clock rate.
The two tone generator should be on before executing this command. If this command is executed
before the two tone generator is active, the entered value will be overridden by a calculated factory
default value.
Example
:RAD:TTON:ARB:SCL:RATE 1MHZ
The preceding example sets the ARB sample clock to 1 MHz.
*RST +1.00000000E+008
Range 1E3 to 1E8
Key Entry ARB Sample Clock
[:STATe]
Supported N5172B/82B
[:SOURce]:RADio:TTONe:ARB[:STATe] ON|OFF|1|0
[:SOURce]:RADio:TTONe:ARB[:STATe]?
This command enables or disables the on/off operational state of the two–tone waveform generator
function.
Example
:RAD:TTON:ARB ON
The preceding example turns on the two–tone generator.
*RST 0
Key Entry Two Tone Off On
Range <startFreq> 1 Hz to 100 MHz
<stopFreq> 1 Hz to 100 MHz
<numSamples> 1 to 8192
