R&S FSP Instrument Functions
Basic Settings
Name - Entry of name
TRD FACTOR
NAME
The TRD FACTOR NAME softkey is used to enter the name of the transducer factor.
A maximum of 8 characters is permissible for the name. The characters have to
comply with the convention of DOS file names. If the name exceeds 8 characters,
the name is truncated. The unit automatically stores all transducer factors with the
extension .TDF. If an existing name is changed, the factor stored under the previous
name is retained and will not be overwritten automatically with the new name. The
previous factor can be deleted at a later time, using DELETE. Thus, factors can be
copied.
Remote command:
CORR:TRAN:SEL <name>
Unit – Selection of unit
TRD FACTOR
UNIT
The TRD FACTOR UNIT softkey gives access to a box for selecting the unit of the
transducer factor.
The default setting is dB.
Remote command:
CORR:TRAN:UNIT <string>
Entry of value
TRD FACTOR
VALUES
The TRD FACTOR VALUES softkey sets the scrollbar on the first reference value.
The desired reference values for FREQUENCY and TDF/dB must be entered in
ascending order of frequencies. After the frequency has been entered, the scrollbar
automatically goes to the associated level value.
The table can be edited after entry of the first value using the INSERT LINE and
DELETE LINE softkeys. To change individual values later on, the value has to be
selected and a new one entered.
Remote command:
CORR:TRAN:DATA <freq>,<level>
Interpolation - Selection of interpolation
Linear or logarithmic interpolation can be performed between the frequency refer-
ence values of the table. The
ENTER key allows the user to select LIN or LOG (tog-
gle function).
Remote command:
CORR:TRAN:SCAL LIN|LOG
The following diagrams show the effect that interpolation has on the calculated
trace:
