[edit] 1 Purpose
This procedure allows to measure the reflectivity of each antenna. A high reflectivity can be due to a broken antenna or to a bad match. Check connectors and cables.
[edit] 2 Material
- Network Analyzer (NA)
[edit] 3 Procedure 1
- Stop acquisition
- Calibrate the NA for a S11 measurement
- Measure in sequence each antenna by connecting the NA directly to the input of the antenna divider
[edit] 4 Procedure 2
- Stop acquisition
- Disconnect the RF signal cable from the amplifier input (Media:PictureAmpInputDegreane.png)
- Calibrate the NA for a S11 measurement
- Connect the NA before the antenna switch
- Configure a one-measurement (vertical) cycle
- Start acquisition
- Measure S11 with the NA
- Repeat steps 5 - 7 for each antenna
