The Advantest R3271A/K is a high-performance spectrum analyzer covering 100 Hz to 26.5 GHz, with external mixer options extending measurement capability to 40 GHz and 60 GHz. It delivers -145 dBm typical displayed average noise level and 95 dB displayed dynamic range, supporting amplitude measurements from -150 dBm to +30 dBm with ±0.5 dB accuracy. The analyzer provides resolution bandwidth from 10 Hz to 3 MHz, video bandwidth to 3 MHz, and sweep times as fast as 5 µs/div in digitized mode. Gated and delayed sweep functions offer gate widths from 1 µs to 1.5 s and delay times from 200 ns to 1.5 s with 100 ns resolution.
