This unit
The Anritsu S331P Site Master is an ultraportable, one-port cable and antenna analyzer engineered for field installation, maintenance, and troubleshooting of wireless communication systems. Available in 4 GHz and 6 GHz models, this instrument delivers the smallest footprint, lowest weight, and fastest measurement speed in the Site Master portfolio. The device operates entirely via USB connection to a Windows tablet or PC - no internal battery required - making it ideal for technicians requiring maximum mobility without sacrificing measurement capability.
