This application note explains how to perform

LTE base station measurements over the air

(OTA) using the R&S

FSH4/8/13/20 handheld

spectrum analyzer. It describes the required

measurement setup and explains the results

obtained with the different measurement

modes.

To execute the tests described in this

application note, the R&S

FSH4/8/13/20

handheld spectrum analyzer (from now on

referred to as the FSH) needs to be equipped

with an antenna and the following software

options:

R&S

FSH-K50 and R&S

FSH-K50E for FDD-

LTE or R&S

FSH-K51 and R&S

FSH-K51E for

TD-LTE.
