level can be adapted automatically to restore the original dynamic range. The refer-
ence level is shifted by the maximum transducer factor. By default, if transducers are
active the reference level function is adapted automatically to obtain the best dynamic
performance.
If a transducer factor is active, "TDF" is displayed in the channel bar.
Y-Axis Unit
The individual transducer factors can be defined as absolute values or relative (dB)
values. However, all factors for one transducer line use the same unit. As soon as a
transducer is activated, the unit of the transducer is automatically used for all the level
settings and outputs. The unit cannot be changed in the amplitude settings since the
R&S
FSV/A and the active transducer are regarded as one measuring instrument. Only
for relative transducer factors (unit dB), the unit originally set on the instrument is main-
tained and can be changed.
When all transducers have been switched off, the R&S
FSV/A returns to the unit that
was used before a transducer was activated.
Configuration
The R&S
FSV/A supports transducer lines with a maximum of 1001 data points. Eight
of the transducer lines stored in the instrument can be activated simultaneously. The
number of transducer lines stored in the instrument is only limited by the capacity of
the storage device used.
A transducer line consists of the following data:
●
A maximum of 1001 data points with a position and value
●
A unit for the values
●
A name to distinguish the transducer lines
Validity
The transducer factors must comply with the following rules to ensure correct opera-
tion:
●
The frequencies for the data points must always be defined in ascending order.
Otherwise the entry will not be accepted and an error message is displayed.
●
The frequencies of the data points may exceed the valid frequency range of the
R&S
FSV/A since only the set frequency range is taken into account for measure-
ments. The minimum frequency of a data point is 0 Hz, the maximum frequency
200 GHz.
●
The value range for the transducer factor is ±200 dB.
●
Gain has to be entered as a negative value, and attenuation as a positive value.
Storing transducer factors
Transducer factors can be exported to a file in ASCII (CSV) format for further evalua-
tion in other applications. Transducer factors stored in the specified ASCII (CSV) for-
mat can also be imported to the R&S
FSV/A for other measurements.
