2.3 Voltage division factor
The test set-up is calibrated with the measurement cables connected as shown in
Figure 7. See FULL-TWO-PORT calibration (TOSM) of the network analyzers.
Fig. 7 Calibration set-up for Voltage Division Factor
The voltage division factor is measured between the Receiver port and EUT port of the
ISN. The measurement is performed by using the Calibration Adapter “Jig CAL
U100B
”. The AE port of the network is terminated with a 150 C resistor (“A-150” or “Jig
TRA U0-150” for R&S ENY81-CA6 respectively). The measuring result is a voltage
division factor of around 9.5 dB. The test set-up for measuring the voltage division
factor is shown in the Figure 8. For R&S ENY81-CA6 it is shown in Figure 9.
