Measure
The measure panel shows which signals are measured during several measuring cycles
when the generator signal is applied on different measurement ports.
These values are read-only and can only be changed by changing the measurement
through the ‘Select Measurement’ button.
The connection diagram of the measurement is displayed at the left of the main screen.
Selecting a measurement
The Measure-pane indicates the
set-up that has been selected. If
you want to change the set-up,
click on
Select Measurement
which
opens
the
VNA-
Measurement dialogue box.
In the
Measurement screen
you
select the measurement set-up, i.e.
on which ports you want to
connect the DUT. Here you can
also indicate that you want to use
an external directional coupler.
The top row and the second last
box at the bottom are regular setup
for
1,
2
and
3-port
measurements
. The last box is a
one-way Through
measurement
(without 12-term normalization) that measures only S11 and S21. This can be used for
faster through measurements. The other setups allow using external bridges and mixers.
Set up the port configuration
During calibration the software needs to know what type of connectors are used on the
ports (cables) so that it can select the correct Calibration Kit element for correcting the
calibration. This port configuration can be set up through the
Port Setup
button. This
brings up the
Port Configuration
screen.
