SURECOM SW-102 Digital VHF/UHF Power & SWR Meter for Handheld radio testing 125-520 MHz

Tutorial of basic use for SURECOM SW-102 Digital VHF/UHF Power & SWR Meter for Handheld radio testing 125-520 MHz Measure VSWR, Forward and reflected power direct digital readout, without any calibration. Maximum measurable power range up to 120W. low insertion loss (0.3 decibels or less) structure allows it to be permanently connected. Build in Frequency counter . Feature & Specification Frequency range: 100 - 520MHz Measurable power range: 0 - 120W Maximum power: 120W Accuracy: mean + / - 5% Impedance: 50Ω Size: W 76 X H 77 X D35 mm. Weight: cca260 grams Interface: N-J Interface The Voltage Standing Wave Ratio (VSWR) is an indication of the amount of mismatch between an antenna and the feed line connecting to it. The range of values for VSWR is from 1 to ∞. A VSWR value under 2 is considered suitable for most antenna applications. The antenna can be described as having a good match. So when someone says that the antenna is poorly matched, very often it means that the VSWR value exceeds 2 for a frequency of interest.
