Offset Load Calibration - Agilent Technologies E5071C Manual

E5071C
Follow these steps to perform calibration using sliding load. The example
demonstrates re-calibration for full 1-port calibration.
1. Press
Channel Next/Channel Prev
you want to perform the calibration.
2. Press
Cal
3. Click Calibrate > Cal Kit.
4. Select the calibration kit with sliding load, for example, 85052B.
5. Press
Cal
6. Click Calibrate > 1-Port Cal > Select Ports.
7. Select the test ports for which you want to perform re-calibration for
full 1-port calibration.
8. Make a OPEN connection on the selected test port.
9. Click Open.
10. Make a SHORT connection on the selected test port.
11. Click Short.
12. Make a LOAD connection on the selected test port with a sliding
load.
13. Click Calibrate > 1-Port Cal > Load > Load 2 Sliding for female
load OR Calibrate > 1-Port Cal > Load > Load 5 for male load. The
assignment of female and male loads varies from one calibration kit
to another. In the case of 85052B, load 2 is a female and load 5 is a
male load.
14. Slide the load to the desired position and click Sliding Load.
Repeat this step for at least 5 times (till Sliding Load 5), then click
Done. This step can be repeated at most 10 times only.
15. Click Return.
16. Now, all Short, Open and Load should have check mark on their
left.
17. Click Done.
The sweep range setting should match the frequency range of the sliding
load. Else, the load process is not executed, hence no check mark appear
on the Load softkey. Similarly, if the frequency range is extended, the load
process is also not executed. Refer to redefining a calibration kit to learn
more about it.

Offset Load Calibration

An offset load is a compound standard consisting of a load element and
two known offset elements (transmission lines) of different length. The
