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 FSW 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 FSW for other measurements.
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 11.3, "Storing and Recalling Instrument Settings and Measurement
Data", on page 625).
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 626.
12.3.2 Transducer Settings
Access: [Setup] > "Transducer"
Up to 8 transducer lines can be activated simultaneously in the R&S FSW. Many more
can be stored on the instrument.
Transducers can also be defined when an optional external mixer is used (R&S FSW-
B21).
Transducer settings in secure user mode
Be sure to store transducer files before SecureUser Mode is enabled; see Chap-
ter 5.1.7, "Protecting Data Using the Secure User Mode", on page 43.
