Calibration for NA, CAT, and VVM Modes
Normalize
uses a THRU standard or cable between port 1 and port 2 to cal an
S21 and S12 Transmission measurement (NA Mode) and a 2-port Insertion
Loss measurement (CAT Mode). In VVM Mode, this is performed using Zero.
When a Normalization is performed, the forward and reverse transmission
tracking terms from CalReady are updated to account for the THRU that is
used during the normalization process.
How to perform a Simple Response Cal
— Select the measurements to be calibrated. See the relevant Mode (NA, CAT,
or VVM) for measurement selections.
— Press
Cal 5
then
Response Cal
— For 1-port measurements:
— Select either
Open Response
or
Short Response
for the port to be
calibrated. The availability of this calibration on Port 2 may require an
option.
— Connect an OPEN or SHORT standard to the specified port and press
Measure
— For 2-port measurements:
— Select
Normalization
— Connect a short, high-quality, phase stable cable between the
FieldFox port 1 and port 2 connectors, then press
Measure
— Press
Finish
.
— Connect the DUT.
CAL ON U
is shown on the screen when a User Cal (Ex: Response Cal) is
correcting ONLY the appropriate measurement. For example, when an Open
Response Cal on Port 2 is performed,
CAL ON U
is shown for an S22
measurement only.
With a Normalization Cal, all subsequent insertion loss measurements are
made relative to the insertion loss of the cable used as the THRU standard.
For example, if you use a cable with 1 dB of loss, then after Normalization,
the display will show 0 dB of loss with this cable in place. Therefore, for
highest accuracy, when measuring the DUT also attach the cable that was
used in the normalization cal.
