6.2.3.1 Controls on the Wave Tab
The "Setup" button opens the S-Params Setup Dialog .
The "More Wave Quantities..." button opens the More Wave Quantities dialog which
allows to select an arbitrary wave quantity , e.g. for different source ports or higher port
numbers.
a<i> Source Port <i>, b<j> Source Port <i>
Selects one of the standard 2-port wave quantities a
i
, b
j
for different source ports.
The predefined wave quantities are obtained with different source ports. "a1 Source
Port 1", "b1 Source Port 1" and "b1 Source Port 2" are measured at Port 1 of the ana-
lyzer. "a2 Source Port 2, b2 Source Port 1" and "b2 Source Port 2" are measured at
Port 2 of the analyzer.
●
"a1 Source Port 1" is the wave transmitted at physical port 1. In a standard S-
parameter measurement, this wave is fed to the input port (port 1) of the DUT (for-
ward measurement).
●
"b1 Source Port 1" is the wave received at physical port 1. In a standard S-parame-
ter measurement, this wave is reflected at port 1 of the DUT (forward measure-
ment).
●
"b2 Source Port 1" is the wave received at physical port 2. In a standard S-parame-
ter measurement, this wave is transmitted at port 2 of the DUT (forward measure-
ment).
●
"a2 Source Port 2" is the wave transmitted at physical port 2. In a standard S-
parameter measurement, this wave is fed to the output port (port 2) of the DUT
(reverse measurement).
