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> S
ij
, 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 S
ij
trace we have multiple traces S
ij
v
a
t
i
v
b
t
j
. E.g. "S21v1t1v3t2"
means that S21 is measured with VNA port 1 connected to the input port and VNA port
3 connected to the output port.
Start Cal Sweep
The dock widget below the diagrams shows the calibrated port(s) and standards and
visualizes 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 "Calibration" tab of the
,
an additional "Calibration Info" dialog is displayed, from where the cal sweep is actually
started.
"Don't Show this Dialog Again" has the same effect as disabling "Show Cal Kit Label" .
A green checkmark indicates that the calibration data of a standard has been acquired
successfully. A green checkmark after the port symbol indicates that the minimum
number of calibration measurements for the port has been performed.
Tip:
●
If the selected calibration kit comprises a Sliding Match, then for every required
Match measurement either the Match or at least three positions of the Sliding
Match must be measured. See
Chapter 4.5.2.3, "Sliding Match Standards"
●
For a TRL calibration, at least one line standard must be measured between any
pair of calibrated ports. See
Chapter 4.5.1.9, "TRL Calibration"
