Wayne Wong, product manager at Anritsu, introduces the S331P, an ultra-portable version of the Site Master, Anritsu's tower testing hardware.
The S331P is the smallest, lightest and "most cost-effective" Site Master. It can be directly connected to devices under test, and has a frequency range from 150 kZh to 6 GHz. This means it can be used to test RF-radio equipment on the low end, and LTE-U at 5GHz on the high frequency range.
It is small enough to fit in someone's pocket for convenience when climbing towers.
