Calibration
Correction Function Calls
SYSTEM CAL menu:
CAL
SHORT
The CAL SHORT softkey starts a short calibration, in which the absolute gain
of the analyzer as well as the gain errors of the selected bandwidth are
corrected.
IEC/IEEE- bus command :CALibration:SHORt?
CAL
TOTAL
The CAL TOTAL softkey starts a complete correction of the receiver including
additional partial corrections shown in the menu.
UNCAL is displayed in the status line if the correction data recording has
failed or if the correction values are deactivated (CAL CORR softkey= OFF).
IEC/IEEE- bus command :CALibration[:ALL]?
CAL
RES BW
The CAL RES BW softkey starts the correction of the center frequency, the
bandwidth and the gain of the resolution filter.
IEC/IEEE- bus command :CALibration:BANDwidth[:RESolution]?
CAL LOG
The CAL LOG softkey starts the correction of the linearity of the logarithmic
amplifier.
IEC/IEEE- bus command :CALibration:LDETector?
CAL
LO SUPP
The CAL LO SUPP softkey starts the correction of the compensation of the
first oscillator at low frequencies. After correction, the display of the internal
oscillator at the frequency 0 Hz is very small.
It is recommended that the correction be performed whenever sensitive
measurements are to be made at low frequencies.
CAL I/Q
The CAL I/Q softkey starts the correction of the gain error of the I/Q
demodulator.
The softkey is only available in conjunction with option FSE-B7.
IEC/IEEE- bus command :CALibration:IQ?
