Priced at only $80, the portable RF Meter is a low-cost signal-strength measurement tool for designers of RF radio systems. Two models are available to detect signals at 315 MHz or 433.2 MHz. Radio-transmitter signal strength is indicated by a 10-digit LED display with a one-second peak hold function to simplify measurement readings. The unit operates from a 9-V flat battery, and it has low-battery indication and an auto-shutoff feature that activates after 60 seconds of no operation. RF sensitivity is −110 dBm. The IF bandwidth is 600 kHz. Housed in a 4.33- by 2.56- by 0.94-in. ABS enclosure, it operates from 0°C to 60°C.
