Reflection Procedure
Selecting the
Reflection part of the procedure
guides you through these additional steps to measure an
open circuit, short circuit, and fixed load at Port 1 and an
open circuit, short circuit, and fixed load at Port 2. So, if the
start frequency is less
than 2
and you
wish to use the
open/short/load technique for calibration below 2
then after measuring the Thru, Reflect, Isolation and
standards and before pressing SAVE TRL 2-PORT, perform
the following
reflection sequence.
Measure Thru, Reflect, Isolation, and Line standards. If the
start frequency is less
than 2
press
REFLECTION.
l
Press
REFLECT’N
l
Connect the Short circuit to Port 1 and then press
SHORT.
. Connect the Open circuit to Port 1 and then press
OPEN.
l
Connect the Fixed Load to Port 1 and then press
LOAD.
l
Connect the Short circuit to Port 2 and then press
SHORT.
l
Connect the Open circuit to Port 2 and then press
OPEN.
. Connect the fixed load to Port 2 and then press
LOAD.
l
Press REFLECT’N DONE.
l
Press SAVE TRL
and then
CAL SET 1,
(or any
other cal set).
When SAVE is pressed, error coefficients from measurement
of the Open, Short, and Load are used for frequencies
below
2
and coefficients from measurement of the Thru, Reflect
and Line are used for frequencies
above
