The "More Wave Quantities..." button opens the
dialog which
allows to select an arbitrary
, e.g. for different source ports or higher port
numbers.

Selects one of the standard 2-port

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 test port 1. In a standard S-parameter
measurement, this wave is fed to the input port (port 1) of the DUT (forward mea-
surement).
●
"b1 Source Port 1" is the wave received at test port 1. In a standard S-parameter
measurement, this is the reflected wave at port 1 of the DUT (forward measure-
ment).
●
"b2 Source Port 1" is the wave received at test port 2. In a standard S-parameter
measurement, this wave is transmitted at port 2 of the DUT (forward measure-
ment).
●
"a2 Source Port 2" is the wave transmitted at test port 2. In a standard S-parameter
measurement, this wave is fed to the output port (port 2) of the DUT (reverse mea-
surement).
●
"b1 Source Port 2" is the wave received at test port 1. In a standard S-parameter
measurement, this wave is transmitted at port 2 of the DUT (reverse measure-
ment).
●
"b2 Source Port 2" is the wave received at test port 2. In a standard S-parameter
measurement, this wave is fed to the output port (port 2) of the DUT (reverse mea-
surement).
Tip:
In the trace list the source port is indicated in brackets. "a1(P1)" denotes the wave
a
1
with source port 1.
The analyzer can also measure arbitrary wave quantities for other source ports; see
