When all transducers have been switched off, the R&S FPL1000 returns to the unit that
was used before a transducer was activated.
Configuration
The R&S FPL1000 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
FPL1000 since only the set frequency range is taken into account for mea-
surements. The minimum frequency of a data point is 0 Hz, the maximum fre-
quency 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 also be stored with the configuration settings so they can be
recalled for other measurements at a later time. Note, however, that any changes
made to the transducer factors
after storing the configuration file cannot be restored
and will be overwritten by the stored values when the configuration file is recalled.
Always remember to store the settings again after changing the transducer factors.
(See Chapter 6.2.2, "Storing and Recalling Instrument Settings and Measurement
Data" , on page 98).
Recalling transducer factors stored with measurement settings
After recalling measurement settings, the transducer factors applied to the measure-
ment may be different to those displayed in the "Transducer" dialog box; see
"Saving
and recalling transducer and limit line settings" on page 100.
