Handheld cable and antenna analysers

The S331D and S332D Site Master cable and antenna analysers feature a number of improvements in performance and operation that make it easier to conduct accurate return loss/SWR, cable loss, and distance-to-fault (DTF) measurements on wireless networks. The analysers allow wireless network technicians to rapidly evaluate the health and status of installed transmission lines and antenna systems before a major failure occurs, while also expediting the benchmarking of new cell site installations during commissioning.

The models are designed with the FlexCal broadband calibration feature. FlexCal simplifies the troubleshooting of cable and antenna systems because it eliminates the need for multiple instrument calibrations and calibration set-ups.

With a measurement range of 25 MHz to 4 GHz, the analysers cover all cell site frequency ranges without additional plug-ins or modules required. They feature immunity-to-interference of +17 dBm on-channel and -5 dBm on-frequency, so that accurate and repeatable measurements can be made in high RF-noise environments.

They also feature an increased sweep speed of <500 ms per sweep that enables easier identification of intermittent, real-time problems. Distance measurement resolution and fault location are optimised by the 130, 259 and 517 data points.

One-button measurement capabilities include interference analysis and carrier-to-interference ratio. As many as 70 signal standards are built in, which further simplifies measurements by eliminating the need to perform channel-to-frequency translation.

To reduce coverage holes and interference, the analysers feature an optional built-in power meter that allows power measurements to be made without need of external sensors. The internal circuitry gives the analysers a broadband capability whereby users can specify an exact frequency range to measure power rather than be limited by a wideband power sensor.
