Response and Isolation Error-Correction for Reflection Measurements

Although you can perform a response and isolation correction for reflection measurements, Hewlett-Packard recommends that you perform an S1l one-port error-correction; it is more accurate and just as convenient.

1.Press B.

2.Select the type of measurement you want to make.

•I If you want to make a reflection measurement on PORT 1 (in the forward direction, &I), leave the instrument default setting.

qIf you want to make a reflection measurement on PORT 2 (in the reverse direction, S&, press:

3.Set any other measurement parameters that you want for the device measurement: power, sweep type, number of points, IF bandwidth.

4.To access the measurement correction menus, press:

7.Connect the short or open calibration standard to the port you selected for the test port (PORT 1 for S11 or PORT 2 for $2).

Note	Include any adapters that you will have in the device measurement. That is,
	connect the standard device to the particular connector where you will connect
	your device under test.
