Features Aluminum Alloy Material The mini standing wave knife uses the high quality aluminum alloy shell, which is strong and durable. Algorithm Correction The correction of the 1024 point interpolation algorithm is performed on the non-linearity of the diode in the software, and can simultaneously display the standing wave, peak forward power PF, peak reverse power PR, average forward power AF and average reverse power AR. Accurate Reading This mini standing wave meter uses an organic light-emitting diode screen display with a resolution of 128*32, the reading is clear and accurate. High Performance The standing wave meter uses 3 magnetic ring detection circuits, can work continuously for 5 hours, MCU is AVR Mega32. Basic specifications: frequency range 1.6MHz to 30MHz, power error ±5%, maximum measuring power 100W, maximum display power 138W.
