The 3280 series has a very high level of accuracy, ±0.15dB up to 3GHz and other performance features include local oscillator phase noise <-115dBm/Hz at 10kHz offset from 1GHz and +18dBm third order intermodulation performance. Digital Intermediate Frequency offers resolution bandwidths from 5MHz to 1Hz.
The Windows XP operating system, internal hard drive and built-in CD ROM make the 3280 series extremely easy to use and allow for a wide range of interfaces, including LAN access, USB, RS-232, IEEE 488 (GPIB) and VGA outputs. Centronics parallel ports are provided for printer, mouse and keyboard connectivity.
The 3280 series has a large 10.4 inch TFT LCD display that gives the user ample viewing area so data can be seen easily, even in split screen mode or with multiple windows open. 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.
In order 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.
