The AR3000A's high level of performance is achieved by using 15 band pass filters before the GaAsFET RF amplifiers unlike other receivers which may rely largely on broad band amplifiers. This ensures high sensitivity through the entire coverage with outstanding dynamic range and freedom from intermodulation effects.
An RS232 port is provided enabling full remote control via most computers, control facilities include: Frequency, Receiver mode, Frequency steps, Writing to/from memory, Signal strength, RF attenuator, Memory bank changeover, etc. A rear panel switch changes control between the keypad and RS232 port.
The large comprehensive front panel LCD has an improved 12 o'clock viewing angle with illumination to increase visibility. The display includes a real time clock for accurate log keeping. During unattended monitoring use the timer and tape output socket.
