6. To measure the standard, when the displayed trace has settled, press:
The analyzer displays WAIT - MEASURING CAL STANDARD during the standard
measurement. The analyzer underlines the softkey after it measures the
standard.
7. Disconnect the open, and connect a short circuit to PORT 1.
8. To measure the device, when the displayed trace has settled, press:
The analyzer measures the short circuit and underlines the softkey.
9. Disconnect the short, and connect an impedance-matched load to PORT 1.
10.To measure the standard, when the displayed trace has settled, press:
, select the type of load you are using, and then press
when the analyzer has finished measuring the load.
Notice that the softkey is now underlined.
11.Repeat the open-short-load measurements described in the previous steps, but connect
the devices in turn to PORT 2, and use the , ,
and softkeys. Include any adapters that you would include in your
device measurement.
