a1 Source Port 1 ... b1 Source Port 2
Selects the standard 2-port wave quantities a
1
, a
2
, b
1
, and b
2
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 analyzer. "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 measurement).
●
"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 measurement).
●
"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 measurement).
●
"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.
