A “Value for Money” Product

The 2399B is the latest in the range of spectrum
analyzers from Aeroflex providing exceptional per­formance at an exceptional price.

Frequency Accuracy

The local oscillator system in the 2399B is fully
synthesized thus providing accurate frequency
measurements with 1 Hz resolution.

Portability

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

Color Display

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

Comprehensive Marker System

Marker Table

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 2399B provides Delta, Peak Search, Peak Track, 1/Delta, Marker
Track, Marker to Center and Marker to Reference capabilities.

Measurement Limits

The Limits facility allows an Upper and/or a Lower Limit to be set
on the screen of the 2399B. 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 2399B can accept signals between +30 dBm
and -110 dBm while providing protection to ±50 Vdc.

Semi-Automated Measurements

The MMI on the 2399B 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 2399B 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 2399B 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 2399B.

Information Storage

The 2399B 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 3.5 inch FDD (Floppy Disk Drive) for bulk
storage.

Interfaces

IEEE 488-2, RS-232 and Printer (PCL5) interfaces are provided as
standard on the 2399B allowing its integration into automated test
systems and the print out of screen displays.

The 2399B has been designed with future flexibility and expansion in
mind. The operating system and system memory have the capability
to incorporate additional facilities.

DISTANCE TO FAULT SOFTWARE OPTION

The 2399B spectrum analyzer is widely used by field installation and
maintenance engineers for monitoring the spectral output from cell
site transmitters. The new Distance to Fault (DTF) option allows
measurement of VSWR of the RF feed cables and, in the event of fail­ing test limits, will then perform a DTF (TDR) measurement to
identify the faulty part of the feed system.

Experience shows that one of the biggest causes of degradation or
failure of RF communications systems is the transmission line from
the base station transceiver to the antenna.

Testing the Transmission Line

When a new cell site is installed, the key measurement to test the
quality of the installation is the VSWR (return loss) of the feed cable
when terminated with the antenna system. Poor installation will result
in unacceptable return loss (VSWR), reducing the quality of the sys­tem.

Even a system that is well within specification when installed may
degrade with time due to the effects of weather, corrosion or acci­dental damage.

Fast Fault Location (DTF)

The 2399B spectrum analyzer DTF option is designed to enable
users to measure VSWR (return loss) routinely and quickly. In the
event of failure, switching to DTF mode pinpoints the problem area
so that corrective action can be taken.

Distance to Fault

Identifying the faulty component in the system and initiating a repair
is simplified, resulting in less system down time. The 2399B DTF
measurement is real time so it can identify even intermittent faults.

Built-in Features

The DTF software option comes with a built-in Transmission Line
Database that contains the characteristics of the most commonly
used coaxial cables. This eliminates the need to refer to manufactur­ers’ data sheets when configuring the 2399B for DTF operation.
