Learning to Make Reflection Measurements
Step 2. Make an error-correction (measurement calibration)
Follow these instructions to make an S
11
1-port error correction:
1. Select a calibration kit that is appropriate to your device under test. Press
Cal, CAL KIT,
SELECT CAL KIT. Choose the calibration kit that is appropriate to your test device by
pressing the appropriate softkey. For example, if your test device uses type-N 50Ω
connectors, press
N 50Ω. If your test device uses 7-mm connectors, press 7mm, and so on.
2. Press
RETURN, CALIBRATE MENU, S11 1-PORT.
3. Follow the prompts shown on the analyzer display to connect and measure an open,
short, and load on PORT 1.
Any choice of male/female in the calibration process should always be made for the sex
that represents the test port. For example, if the test port had a male, type-N connector,
you would connect the female, type-N calibration device. But when you follow the
prompts on the analyzer to measure a short calibration standard, you would select
SHORT (M), or the sex that represents the test port.
CAUTION To ensure an accurate error correction, you must connect the
calibration standards to the adapters or cables that you will include in
the actual device measurement.
NOTE If a mistake is made, standards can be measured more than once before
pressing DONE 1-PORT CAL.

4. Press
DONE 1-PORT CAL after measuring the three standards.
5. Press
