The R&S FSH-K47 option equips the R&S FSH for 1xEV‑DO base station transmitter measurements. The analyzer measures all key parameters that provide useful information about the signal quality and the power distribution of various code channels. These include the total power, the ratio of peak power to average power, the power of the pilot, MAC and data as well as the carrier frequency offset, the EVM and Rho. This allows the user to detect transmitter impairments such as clipping or intermodulation that are difficult to recognize in the spectrum.

In addition, current traffic activity is displayed. This value shows whether connection problems or low data rates are caused by high traffic activity.

FSH-K47 and FSH-K47E

The R&S FSH-K47E option enables in-depth 1xEV-DO measurements. For a quick overview of adjacent base stations, the R&S FSH provides up to eight PN offsets with corresponding power. The burst power measurement in the time domain is used to check whether the power and timing of the 1xEV-DO frame comply with standard specifications.
