NONE
Uses the current RF signal at the input, i.e. no calibration signal (default).
Remote command:
DIAGnostic:SERVice:INPut[:SELect]
Calibration Frequency RF
Uses the internal calibration signal as the RF input signal.
Remote command:
DIAGnostic:SERVice:INPut[:SELect]
DIAGnostic:SERVice:INPut:PULSed:CFRequency
Spectrum ← Calibration Frequency RF
Defines whether a broadband or narrowband calibration signal is sent to the RF input.
"Narrowband"
Used to calibrate the absolute level of the frontend at 64 MHz.
"Broadband"
Used to calibrate the IF filter.
Remote command:
DIAGnostic:SERVice:INPut:RF[:SPECtrum]
Frequency ← Calibration Frequency RF
Defines the frequency of the internal broadband calibration signal to be used for IF fil-
ter calibration (max. 64
MHz).
For narrowband signals, 64
MHz is sent.
Calibration Frequency MW
Uses the microwave calibration signal as the RF input (for frequencies higher than 8
GHz). This function is used to calibrate the YIG-filter on the microwave converter. The
microwave calibration signal is pulsed.
You can define whether the distance between input pulses is small or wide.
Remote command:
DIAGnostic:SERVice:INPut[:SELect]
DIAGnostic:SERVice:INPut:MC[:DISTance]
Calibration Synthesizer 2
This function is used to check the phase noise of the synthesizers on a certain fre-
quency. You can define the frequency in the corresponding input field.
If you enter a frequency on which calibration is not possible, the R&S
FSPN uses the
next available frequency.
Available if the R&S
FSPN is equipped with the optional hardware and has more than
one synthesizer.
