Quick Start: Learning How to Make Measurements

Learning to Make Reflection Measurements

Step 2. Make a measurement calibration

Follow these instructions to perform an S11 or reflection 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 twice, CALIBRATE MENU S11 1-PORTor

REFLECTION 1-PORT .

3.Follow the prompts shown on the analyzer display to connect and measure an open, short, and load on PORT 1 or the REFLECTION port.

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.

NOTE

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

 

. Only the last measurement data is used.
