Level Correction of Transducers
In more complex test systems, the frequency response of the test setup must be taken
into account in all power measurements to avoid any measurement errors being intro-
duced from sources other than the DUT.
The R&S
ESRP offers the possibility of defining a frequency-dependent attenuation
correction factor (transducer factor).
In the example below, a factor with the following characteristics is defined:
Name:
Transtest
Unit:
dB
Scaling:
lin
Comment:
simulated cable correction
Frequency
Level
10 MHz
0 dB
100 MHz
3 dB
1 GHz
7 dB
3 GHz
10 dB
The factor is defined and can be activated as required.
