The Advantest R3265A is a high-performance microwave EMI-adapted portable spectrum analyzer designed for a frequency range of 100 Hz to 8 GHz. It features a high input sensitivity of -145 dBm, standard GPIB and RS-232C interfaces, and a built-in BASIC controller for automated test routines. Its resolution bandwidth ranges down to 10 Hz, and its fast sweep capabilities down to 5 µs/div make it highly suitable for detailed electromagnetic interference measurements and RF analysis.
