It has never been so easy to locate brief elusive transmissions. Integrated with the AR5000A receiver in the SR1050A system; the AOR SDU-5500 provides a spectrum display of 10 MHz bandwidth between 10 kHz and 3000 MHz! Menu driven operation: All facilities are within easy access through each dedicated function key and on-screen menu. Full interconnection with the AR5000A is achieved. The AR500A0 can be operated from the SDU5500 enabling selection of center frequency, receive mode, etc. Any frequency spotted and monitored by the SDU5500 can be received by the SR1050A straight way. The screen is 4.7 inch diagonal white/blue monochromatic LCD.

Direct reading of the receiving frequency and input level: By placing the cursor on any spot frequency, you can read its frequency and input level on LCD screen. It works as a spectrum analyzer over 10 kHz to 3000 MHz range as the center frequency always becomes the receive frequency.
