Compact sized RF signal strength meter that can be used to show the presence and strength of radio signals in the Sub-1GHz ISM frequency bands. Ideal for use when installing a radio remote control system to determine if other RF signals are present (interference) and also validate the signal strength of the radio transmitter to be installed (range expectation).
Selectable Frequency Bands: 315, 433, 868 and 915MHz
Bandwidth: 1MHz
Transmit and Receive modes
8-step LED bargraph display of signal strength in receive mode
Displayed signal strength range: -108 to -40dBm
Sends short pulses at 0dBm RF output power when in transmit mode
Auto shut-off after 1min
Power supply: +9V PP3 battery
Dimensions: 90 x 54 x 27mm
Requires no radio licence
