Frequency Response And Isolation Error-Corrections; Response And Isolation Error-Correction For Reflection Measurements - Agilent Technologies 8719D User Manual

Frequency Response and Isolation Error-Corrections

Removes frequency response of the test setup.
n
Removes isolation in transmission measurements.
n
You can make a response and isolation correction for the following measurements:
reflection measurements
n
transmission measurements
n
combined reflection and transmission measurements
n
Although you can perform a response and isolation correction for reflection measurements,
Hewlett-Packard recommends that you perform an Sll one-port error-correction: it is more
accurate, and it is just as convenient.
1. Press w.
2. Select the type of measurement you want to make.
If you want to make a reflection measurement on PORT 1 (in the forward direction, Sll),
q
leave the instrument default setting.
If you want to make a reflection measurement on PORT 2 (in the reverse direction, S&,
q
press:
3. Set any other measurement parameters that you want for the device measurement: power,
sweep type, number of points, IF bandwidth.
4. lb access the measurement correction menus, press:
5. If your calibration kit is not the 3.5 mm (2.4 mm, HP 8722D) default, press:
If your type of calibration kit is not listed in the displayed menu, refer to the "Modifying
Calibration Kit Standards" procedure, located later in this chapter.
6. 'Ib 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 Srl or PORT 2 for S&.
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.
