HP 8753E - Frequency Response and Isolation Error-Corrections; Response and Isolation Error-Correction for Reflection Measurements

Frequency Response and Isolation Error-Corrections
n removes frequency response of the test setup
n removes isolation in transmission measurements
w removes directivity in reflection measurements
You can make a response and isolation correction for the following measurements:
w reflection measurements
N transmission measurements
n combined reflection and transmission measurements
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

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.
q If 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:

To select a response and isolation correction, 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.
