Calibration
Measurement calibration over HP-IB follows the same command
sequence as a calibration from the front-panel. For detailed information,

1. Start by selecting a calibration kit, such as 50 ohm type-N
(I:HLt:::t.158;
).
2. Select a calibration type, such as
Sll
l-port (CAL IS 1 1 1;
).
3. Call each class used by the calibration type, such as
F
111
R
i,J
A
R
D
:
0
P
E
t.4
(C:LHSS
11
H
j
)
During a 2-port calibration, the
reflection, transmission, and isolation subsequences must be opened
before the classes in the subsequence are called, and then closed at
the end of each subsequence.
4. If a class has more than one standard in it, select a standard from the
menu presented
(STAHA
to
STAHG).
5. If, during a calibration, two standards are measured to satisfy one
class, the class must be closed with
DOt4E
j
.
6. Declare the calibration done, such as with
D
l1lt.l
E

F’

R
T
1:
H
L
(SHV

j
over HP-IB).
The
STANA
to STANG commands will hold off the HP-IB until
completion because they trigger a sweep. If a class has only one
standard in it, which means that it will trigger a sweep when called, the
class command will also hold off the HI-IB.
Note
Since different cal kits can have a different number of
standards in a given class, any automated calibration
sequence is valid only for a specific cal kit.
