Radio test set extends to 2.7GHz

Edited by the Electronicstalk editorial team Aug 23, 2005

The IFR 3902 service monitor expands the operating range of the IFR 3901 radio test set to 2.7GHz for both generating and receiving analogue and digital RF signals.

New from Aeroflex, the IFR 3902 service monitor expands the operating range of the IFR 3901 radio test set to 2.7GHz for both generating and receiving analogue and digital RF signals.

The IFR 3902 and IFR 3901 radio test systems now feature new system test capabilities.

With firmware release version 1.1, both test systems support analogue duplex test capabilities as a standard feature.

With this firmware release, these test systems support extensive testing for AM and FM radios, including: full analogue duplex operation from 1MHz to 1 or 2.7GHz, respectively; full span spectrum analyser with displayed average noise level of -125dBm; three independent audio modulation sources from 1Hz to 20kHz; three independent audio frequency generators for baseband audio analysis; broadband RF power meters from 100mW to 125W; in-band RF RSSI meter usable to -100dBm; full function wideband spectrum analyser to either 1 or 2.7GHz; full analyser capabilities for RF frequency error, power and modulation accuracy; full audio analysis for SNR and distortion with audio filters; dual-channel oscilloscope usable to 4MHz; full suite of analysis meters with pass/fail parameters; and full Internet remote capability for monitoring front screen features.

The new IFR 3902 and the IFR 3901 now support the optional site monitoring application.

With this new option (IFR3901OPT051) these units can be used for determining effective receiver sensitivity of a particular RF channel.

This allows users to automatically determine the noise floor of their system for site selection and channel interference issues.

As an automated option, the site monitoring function allows a system engineer to set up the unit for a particular channel or frequency and then find the effective sensitivity level, without having to spend valuable time on-site.

Results, including spectral data, are logged directly to the unit's hard drive for long-term recording of critical RF performance parameters.

No external computer system is required to run these tests.

Along with the effective sensitivity level monitoring, the system also provides a rapid capture mode of spectrum data if a sensitivity threshold level is passed.

This allows engineers to view interference issues with time and date stamped data without having to be on-site.

These new test features are compatible with SAT Corp's new SigMon 4000 advanced site monitoring software suite.

This suite expands the power of the IFR 3901 or IFR 3902 to do advanced analysis of noise floor and interference issues.

The SigMon 4000 also provides long-term data logging and report generation to collect "evidence" that allows the system engineer to quickly determine if problems lay within the system or are attributable to RF interference issues.

Over the last 15 years, hundreds of customers have used this documented evidence to resolve site and system interference problems directly with interfering organisations and with regulatory agencies.

Delivery for the IFR 3902 is 8 weeks on receipt of order.

Highly configurable, a starting configuration for the IFR 3902 is priced at approximately US $29,950.
