Making Measurements
Measuring S-Parameters using a Two-Port Calibration
Chapter 6 provides detail about when a user-defined calibration is
necessary, and information about other calibrations available for
S-parameter measurements. If you wish to perform a two-port
calibration on your insertable device, execute the following steps:
1. Select calibration kits for both ports: since port 1 will use the default
calibration kit (female type-N), this selection is already made for you.
For port 2, press and use the front
panel knob or the keys to highlight Port 2 in the
display’s table. Press .
2. Press . If
you want to correct for crosstalk errors, toggle the
key ON (for more information about isolation,
refer to the definition of a user two-port calibration in Chapter 6).
3. When the instrument prompts you to connect a through cable, insert
a cable with type-N(m) connectors between port 1 and port 2 as
shown in the Figure 3-6. Press . When done,
disconnect the cable from port 1 but leave it connected to port 2.
4. The instrument prompts you to connect three standards (open, short,
and load) to port 1 as shown in the graphic on the next page.
