GENERAL INFORMATION
1.1 INTRODUCTION
The CT Systems Model 2500 is a cellular tester, cell site
and communications service monitor combined into one small,
use package.

The Model 2500 is specially designed for cellular testing and
includes a "Go-No-Go" automatic mode for quick cellular telephone
testing. A parallel printer port is provided so a hard copy of the
test results can . be generated when a user provided printer is
connected.
A manual mode enables the user to program individual parameters for
trouble shooting purposes. A non-volatile memory allows the user to
store frequently used system parameters.
Testing routines include cell site to mobile initiated calls; mobile
to cell site calls; cell site voice channel handoff; RF power level
control messages; mobile DTMF dialing; voice channel SAT and ST
frequency and deviation measurements.
Displays include mobile dialed number; mobile ID number, ESN (equip-
ment serial number) and station class mark.
In the Service Monitor Mode, the Model 2500 generates and receives
from 400 kHz to 999.9999 MHz in 100 Hz steps. The RF output leyel is
continuously variable from 0.1 uVolts to 10 mVolts in five ranges.
The Model 2500 contains a 1 kHz modulation source, a 10 Hz to 10 kHz
audio synthesizer and an external modulation input. The audio
synthesizer output has a second independently variable output on the
front-panel. Deviation markers at ±5 kHz or ±600 Hz may be
superimposed on the demodulated output for viewing on an external
oscilloscope in both the Receive and Generate modes.
The Model 2500 measures and displays SINAD in dB or % distortion,
volts, FM deviation, signal strength, carrier frequency, demodulated
audio frequency, error frequency and sub-tone.
Power may be applied to the RF in/out connector for measuring R.F.
power up to 110 watts (when terminated into a true 50 ohm load).
Twenty memory registers are available for storing and recalling all
front-panel keyboard settings. An optional RS-232 interface and two
available software packages allow for its use in automated test
systems.
