Figure 5-25: Multiple traces due to multiple paths
The purpose of the typical result traces "Trc1"" and "Trc2" is to avoid connection errors
and to track hardware problems: if the correct standard type is measured, and every-
thing is properly connected, then the measured traces are expected to be similar to the
typical trace.
The S-Parameter traces are labeled P[j_i]_<standard type> Sij, where j indicates the
input (test) port and i indicates the output port, e.g. P[1_2]_Unknown_Through S21.
If switch matrices are involved, the label also indicates:
●
which VNA port b is switched to the input port j and
●
which VNA port a is switched to the output port i
Instead of a single Sij trace we have multiple traces Sijvativbtj. E.g., "S21v1t1v2t2"
means that S21 is measured with VNA port 1 connected to the input port and VNA port
2 connected to the output port.
Start Cal Sweep
The dock widget below the diagrams shows the calibrated ports and standards and vis-
ualizes the measurement progress.
Use the buttons representing the calibration standards to start the corresponding cali-
bration sweeps.
If "Show Cal Kit Label" is enabled on the
an additional "Calibration Info" dialog is displayed. In this case, the cal sweep is started
from this dialog.
