Making Measurements
Measuring S-Parameters using a Two-Port Calibration
Method B: Modify the Calibration Kit Definition of the
Through Standard.
With this method, it is only necessary to use one adapter. The calibration
kit through-standard definition is modified to compensate for the
adapter and then saved as a user kit. However, the electrical delay of the
adapter must first be found. Two examples of this method will be
described: in example #1, the noninsertable device’s input and output
connectors are the same, and in example #2, the connectors are different.
NOTE
By convention, cal kit labels in the analyzer indicate the sex of the port
with which they are used. For example, the default cal kit for the
analyzer is type-N female because the front panel RF ports are female
(the calibration standards, in turn, have male connectors).
EXAMPLE #1: the noninsertable device has type-N female input
and output connectors.
NOTE
For analyzers with 50 ohm input impedance only: in the 50 ohm type-N
calibration kit (HP 85032B), there are four equal adapters: two
APC-7-to-type-N(f), and two APC-7-to-type-N(m). To create the adapter
in the following example, connect two APC-7-to-type-N(f) adapters.
1. Connect a test cable with type-N(m) connectors to the analyzer’s
port 1.
2. Connect a test cable with type-N(m) connectors to the analyzer’s
port 2.
3. To select a calibration kit for port 2, press
(
or
)
, and use the
front panel knob or the
keys to highlight Port 2 in the
display’s table. Press
.
4. Press
. Perform a one-port reflection
calibration using type-N(f) standards on the type-N(m) open-end of
the port 2 cable. Refer to
“Perform a User One-Port Calibration” on
.
5. Connect the type-N female-to-female adapter to the type-N(m) open-
end of the port 2 cable.
6. Add a type-N(m) short to the open end of the adapter as shown in
.
