Atec IFR-1900CSA - Manual (Page 2)

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.
AC1009W - EasySpan TM is a Windows-
based software utility which extracts
spectrum analyzer and tracking generator
traces from the IFR-1900 CSA.
AC1017 - AutoCell-Series II is a
comprehensive program for FCC
compliance testing of Lucent Series II cell
sites.
AC1019 - EasySweep TM is a swept
measurement utility designed to test
antennas and transmission lines.
AC1020D - AutoCell NTD provides
automated testing of Northern Telecom cell
sites.
AC1021 - CellScan TM cellular utility
software simplifies combiner alignment,
monitoring RF levels and base stations on
DAMPS, NT400 or PCS cellular channel
sets.
AC1027 - AutoCell-882/884 is an
autotest program for performing
acceptance tests on Ericsson
884/882/882D/882M/882DM base
stations.

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, single and multi-
mode, 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.
