Aeroflex announced the 3280 series, a line of 3 Hz to 26.5 GHz spectrum analyzers. The 3280 series has a high level of accuracy, ±0.15dB up to 3GHz and a local oscillator (LO) phase noise <-115dBm/Hz at 10kHz offset from 1GHz and +18dBm third order intermodulation performance. Digital Intermediate Frequency (IF) offers resolution bandwidths from 5MHz to 1Hz.

The 3280 series has a 10.4 inch TFT LCD display. Three traces can be displayed per window and as many as nine markers can be selected with a marker table viewable in an alternate window. To simplify the evaluation of many common measurements, the 3280 series offers several built-in functions, including channel power, adjacent channel power, occupied bandwidth, spectrum emission mask, third-order-intercept (TOI) measurement, harmonic distortion, X dB down and phase noise measurement.

The Aeroflex 3280 series comprises three models including the 3281 with frequency range from 3Hz to 3GHz, the 3282 with frequency range from 3Hz to 13.2GHz and the 3283 with frequency range from 3Hz to 26.5GHz.
