Measurement Limits 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. Wide Signal Measurement Range The 50 ohm input on the 2399C can accept signals between +30 dBm and -110 dBm while providing protection to ±50 Vdc. Semi-Automated Measurements 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. Auto-Tune Function Use of this function allows an unknown signal to be quickly captured and displayed on the screen. The 2399C will search its complete frequency range for the highest level signal, capture it and display it in the center of the screen with both the span and resolution bandwidths being automatically set to the optimal state for best viewing. Spectral Purity The phase noise on the 2399C is specified at -90 dBc at 10 kHz offset which allows its use for evaluating the spectral purity and noise performance of systems and sub-systems. Signal Demodulation Demodulation of both AM and FM signals allows full testing on a wide range of communications systems. The demodulated signal can be viewed on the screen and is also available on the internal loudspeaker and on headphones via a connector on the front panel. The FM peak deviation and AM modulation depth can be measured using the markers provided in the 2399C. Information Storage 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 2.0 interface for download to bulk storage. Interfaces 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.
