Atec IFR-1900CSA User Manual

Fully Featured TIA/EIA-136 (TDMA) Test
Solution

The IFR-1900 CSA provides you with the
industrys only accepted test solution for
TIA/EIA-136 analysis, including critical
adjacent power measurements and power
measurements down to -40 dBm, which
allows the user to test the base station

without taking it off-line.

It is capable of performing the critical
dual-mode analog/digital authentication
and protocol compliance tests for
TIA/EIA-136 dual mode mobiles.

As for flexibility, the IFR-1900 CSA
provides the capability to perform both
mobile and base station conformance
testing. And with the VSELP and ACELP
vocoder technology as standard features,
the IFR-1900 CSA can handle todays
latest technology.

The IFR-1900 CSA comes with a wide
array of application software options. The
AC1036 Protocol Conformance Test
Software provides an excellent way to verify
software conformance of TIA/EIA-136
mobiles. Other applications software
supports automated tests for the most
widely used base station applications.

AMPS Solutions

Engineered to be a true dual-mode test
solution, the IFR-1900 CSA also
incorporates AMPS and NAMPS mobile
and base station compliance test features.

Full AMPS testing modes are available with the

IFR-1900 CSA

Automatic test routines and user
defined print outs enhance manual mode
testing for both mobiles and base stations.

Open control channel simulations, voice
channel signaling, home/roam condition,
home SID, SAT, DSAT, DST, DCC, SINAD
reference points, RF power windows, and
other AMPS/NAMPS functions and
signaling routines allow complete AMPS
and NAMPS system testing.

A Full Complement of Service Monitor
Functions to 2 GHz.

The IFR-1900 CSA gives you full
frequency domain analysis to 2 GHz with a
fully featured spectrum analyzer and
tracking generator built-in.

The IFR-1900 CSA also offers a full
complement of standard service monitor
features including a full span digitized
oscilloscope to 1 MHz, DVM and SINAD
functions, frequency and channel tables,
selectable IF filters, and a wide variety of
displays.

The IFR-1900 CSA gives you full featured service

In addition to the 2 GHz RF generator,
the IFR-1900 CSA also provides full
audio/data generator capabilities, full level
control and measurement facilities and
precision power control features for
enhanced sensitivity and high accuracy
testing needs.

Analog paging encoding/decoding,
DTMF, tone coded squelch, digital squelch,
AM modulation/demodulation along with
two separate AF generators and cross band
duplex gives added test versatility in a
variety of wireless systems.

Software Options Make Complex
Testing Simple

As with every IFR test set, you get the
advantage of IFR applications engineering
support.

Our comprehensive portfolio of
application software options are designed
to automate and expand the functionality
of your instrument.

Plus, on-going software support means
that you can easily upgrade your
IFR-1900 CSA when test and service
requirements change.

Dynamic IQ Constellation Display
Simplifies Analysis

The IFR-1900 CSA provides you with a
dynamic constellation display for precise
RF modulation analysis of DQPSK digitally
modulated waveforms from 10 MHz to
2010 MHz. This unique IFR-1900 CSA
feature gives a near real time display for
testing and troubleshooting, an ability that
points out the cause of the trouble in digital
radios.

IQ Constellation display allows for comprehensive

digital modulation testing

Complex Functionality Made Easy

Even with its elaborate capabilities, the
IFR-1900 CSA was developed to execute
complex tests simply and with minimal
operator training.

Using field-proven front panel and user
man-machine interfaces, the IFR-1900 CSA
gives you the performance and ease-of-use
features that reduces your testing and
training time.

Its test macro command programming
language (TMAC) can be easily configured
to perform automatic base station testing
and remote terminal, singl

e and multi­mode, single and multiband equipment.
This powerful capability allows you to
create and save simple one button test
routines for future use. This flexibility
means you can create and execute
complex and repeatable routines no matter
what your level of expertise.

A new color VGA display gives
IFR-1900 CSA users vivid screen clarity.
Extensive use of softkeys reduces your
complex cellular / PCS parametric and
protocol tests to fast, simple and
manageable routines.
