The PM-1A is a high-power, high-precision RF power meter designed specifically for the FM broadcast band (85-110MHz). It belongs to the PM-1x series of power meter standing wave meters, featuring a fully CNC-machined aluminum alloy cavity coupler with silver-plated conductors. Its insertion VSWR and isolation performance significantly exceed the Bird 43 series.
The meter adopts a high dynamic range radio frequency detection circuit, paired with a precision-machined cavity coupler, to deliver accurate bidirectional (forward + reflected) RF power measurements. An integrated high-precision temperature sensor compensates for measurement errors caused by ambient temperature changes, ensuring reliable readings in field conditions.
With Bluetooth 5.0 wireless connectivity, the PM-1A eliminates cable clutter and enhances anti-interference capability. It supports stable real-time monitoring on Android and HarmonyOS devices via dedicated app. This makes it an essential tool for broadcast engineers installing, tuning, and maintaining FM transmitter systems.
Elecsky RF provides full technical support and after-sales service for all products. The PM-1A is ideal for professional broadcast stations, transmitter manufacturing QC, and field RF engineering applications.
