Anritsu Site Master Series

This category includes standard models focusing primarily on reflection and transmission line verification. The series features options starting with legacy units like the Anritsu S331A, Anritsu S331B/S332B, and Anritsu S331C/S332C, which operate from 25 MHz up to 3300 MHz. The Anritsu S331D extends this range from 25 MHz to 4.0 GHz, utilizing Frequency Domain Reflectometry (FDR) for precise DTF calculations.

Modern revisions such as the Anritsu S331E and Anritsu S331L operate over a wider band from 2 MHz to 4.0 GHz, with the S331L featuring an integrated InstaCal calibration module and internal power meter. For higher frequency coaxial applications, the Anritsu S361E extends coverage from 2 MHz to 6 GHz.

To reduce the number of tools required in the field, several Site Master instruments integrate a full spectrum analyzer alongside cable and antenna test systems. The Anritsu S332D provides cable and antenna testing up to 4.0 GHz paired with a 100 kHz to 3.0 GHz spectrum analyzer.

The updated Anritsu S332E covers 2 MHz to 4 GHz for cabling and 100 kHz to 4 GHz for spectrum/interference analysis. For high-frequency deployments, the Anritsu S362E provides dual-functionality up to 6 GHz, combining a 2 MHz to 6 GHz cable and antenna analyzer with a 9 kHz to 6 GHz spectrum analyzer, housed in a robust frame with an 8.4-inch color resistive touchscreen.

For high-frequency microwave and radar installations, the Anritsu S820D provides standard coverage from 25 MHz to 20 GHz, which can be extended down to 2 MHz using Option 2. It supports both coaxial cables and waveguide media, incorporating waveguide dispersion correction for accurate fault location.

For duplexer and tower-top environments requiring 2-port measurements, the Anritsu S251B and Anritsu S251C operate in the 625 MHz to 2500 MHz band, enabling isolation, gain, and insertion loss measurements alongside standard reflection parameters.
