Performing the test, part 1
The test is a S21 measurement on the vector network analyzer.
► Normalize Port 1 - Port 2 of the vector network analyzer.
Preparing the EUT, part 2
1.
DANGER!
Do not connect the R&S
ESH3-Z6 to mains voltage for the test. Con-
necting the R&S
ESH3-Z6 to the mains voltage poses hazardous or even life-
threatening risks to the operator.
Arrange the test set-up as shown in
.
2. Connect the Port 2 through the BNC 10
dB attenuator to the X3 connector.
3. Connect the BNC 50
Ω
termination to the BNC T – Branch input.
