Full One-Port Cal...
Opens the calibration wizard to perform a full one-port calibration at port no. 2. The calibration serves
several purposes:
•
Define the reference plane (zero distance).
•
Normalize the trace (total reflection of the signal corresponds to a 0 dB peak).
•
Avoid spurious effects, e.g. peaks on the impulse response trace that are not due to a fault.
If necessary, the analyzer also increases the number of points; see
Auto Number of Points.

Fault Limit...
Defines a minimum response value in dB for a trace maximum to be considered as being due to a fault.
The fault limit is defined relative to the 0 dB-line in the test diagram, i.e. the peak response value for total
reflection after proper calibration. The fault limit is handled like any other trace limit:
•
Defining a fault limit overwrites the previously defined limit lines for the active trace. The fault limit
forms a new upper line segment which is displayed in the
Define Limit Line
dialog.
•
If
Trace – Lines –
Show Limit Line
is enabled, the fault limit is displayed as a horizontal limit line.
•
If the limit check is enabled
(Limit Check On),
peaks above the fault limit can change their color,
and a
PASS
or
FAIL
message is displayed.
