If a new TTC/12TC calibration shall be performed, the wizard asks for
the calibration kit to be used.
•
In the following steps the standards
Open
,
Short
and
Load
(50
Ω
) have
to be measured. The wizard automatically jumps to the next step. The
user can use the
Back
button to redo a measurement.
•
For a 12TC calibration the additional
Thru
and
No connection
measure-
ments (50
Ω
loads or alternatively no standards on both ports) have
to be carried out.
•
Please note that a 12TC automatically includes DTTC & single-ended
TTCs on both ports. DTTC includes single-ended TTCs on both ports.
•
The number of averages for the TTC/12TC measurements can be set in
the
Oscilloscope Window
(recommendation
≥
50
, especially for high
frequency measurements it can be advantageous to set averaging up
to
2000
).
•
In the last step the user can optionally save the TTC/12TC data to a
project file. This method can be of interest for users working with fre-
quently changing TTC/12TCs (e.g. due to changing time bases). If you
work with an unchanging measurement setup, saving the TTC/12C is
not necessary at this stage.
Please note:
This feature will become obsolete in future software releases. It
is recommended to save TTC/12TC calibrations as standard project mas-files
instead of wizard-saved files.
•
On completion of the wizard the TTC/12TC data is automatically stored
for reuse (see
: Reload last known). The previous TTC/12TC is re-
placed and
cannot be recovered
anymore.

In case a
multiplexer
is connected, please refer to chapter
for fur-
ther information about calibrating multiple channels.
