R&S FSP Instrument Functions
Basic Settings
Remote command:
CORR:TRAN DEL
VIEW
TRANSDUCER
The VIEW TRANSDUCER softkey activates the display of the active transducer fac-
tor or set. During the measurement, the interpolated characteristic of the active
transducer factor or set is shown in the diagram instead of the measured values.
Remote command:
CORR:TRAN:VIEW ON
REFLVL ADJ
AUTO MAN
When a transducer factor is used, the trace is moved by a calculated shift. However,
an upward shift reduces the dynamic range for the displayed values. With the soft-
key
REFLVL ADJ an automatic reference level offset adaptation allows to restore
the original dynamic range by also shifting the reference level by the maximum
value of the transducer factor.
If transducers are active the function is automatically set to AUTO to obtain the best
dynamic performance.
Remote command:
CORR:TRAN:SEL 'FACTOR1'
CORR:TRAN:ADJ:RLEV ON | OFF
PAGE UP The PAGE UP softkey is used to scroll through large tables that cannot completely
be displayed on the screen.
PAGE DOWN The PAGE DOWN softkey is used to scroll through large tables that cannot com-
pletely be displayed on the screen.
Entry and Editing of Transducer Factors
A transducer factor is characterized by the following:
• Reference values with frequency and factor ( Values )
• Unit of the factor ( Unit ) and
• Name ( Name ) to distinguish the various factors.
During entry the R&S FSP checks the transducer factor for compliance with specific
rules that must be met to ensure correct operation.
• The frequencies for the reference values must always be entered in ascending
order. Otherwise the entry will not be accepted and the following message is
displayed:
WRONG FREQUENCY SEQUENCE !
• The frequencies entered may exceed the frequency range of the R&S FSP since
only the set frequency range is taken into account for measurements. The
minimum frequency of a reference value is 0 Hz, the maximum frequency
200 GHz.
• The value range for the transducer factor is ±200 dB. If the minimum or maximum
value is exceeded, the R&S FSP outputs the following message:
out of range
• Gain has to be entered as a negative value, and attenuation as a positive value.
