The 2399C is the latest in the range of spectrum analyzers from Aeroflex providing exceptional performance at an exceptional price. The local oscillator system in the 2399C is fully synthesized thus providing accurate frequency measurements with 1 Hz resolution.

With a weight of only 9.4 kg (20.7 lbs.) the 2399C is one of the lightest spectrum analyzers available. A truly portable unit!

The 6.4 inch TFT color LCD in the 2399C provides a clear, bright, sharp display with a 640 x 480 pixel active display area viewable in high ambient light conditions.

The marker system allows up to a maximum of 9 markers to be displayed on the screen at any one time. A marker table shows the frequency and level of each marker selected thus allowing multiple signals to be evaluated simultaneously. In addition to the Normal markers 2399C provides Delta, Peak Search, Peak Track, 1/Delta, Marker Track, Marker to Center and Marker to Reference capabilities.

The Limits facility allows an Upper and/or a Lower Limit to be set on the screen of the 2399C. Should the signal being displayed fall outside either limit a message will appear on the screen showing which limit has been exceeded and how many times this has happened.

The 50 ohm input on the 2399C can accept signals between +30 dBm and -110 dBm while providing protection to ±50 Vdc.

The MMI on the 2399C has been designed to simplify many of the measurements required for the evaluation of today’s sophisticated communications systems. These include Adjacent Channel Power, X dB Down, Occupied Bandwidth, Channel Power and Harmonic Distortion.

The 2399C is provided with the capability of internally storing up to 1,000 screen traces and 2,000 operational states. The spectrum analyzer is also fitted with a USB IEEE 488-2, RS-232 and Printer (PCL5) interfaces are provided as standard on the 2399C allowing its integration into automated test systems and the print out of screen displays. The 2399C has been designed with future flexibility and expansion in mind. The operating system and system memory have the capability to incorporate additional facilities.
