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).
●
"b1 Source Port 2" is the wave received at physical port 1. In a standard S-parame-
ter measurement, this wave is transmitted at port 2 of the DUT (reverse measure-
ment).
●
"b2 Source Port 2" is the wave received at physical port 2. In a standard S-parame-
ter measurement, this wave is fed to the output port (port 2) of the DUT (reverse
measurement).
Tip:
In the trace list, the source port is indicated in brackets. For example, "a1(P1)"
denotes the wave a
1
with source port 1.
The analyzer can also measure arbitrary wave quantities for other source ports; see
Chapter 5.2.3.2, "More Wave Quantities dialog"
Note:
For a unidirectional R&S
on page 80) wave quantities for source port 2 are not avail-
able.
Remote command:

More Wave Quantities dialog
The "More Wave Quantities" dialog provides arbitrary wave quantities with arbitrary
source ports as measured quantities. All wave quantities can be calculated with differ-
ent detector settings.
