Protocol capture and analysis with radio
test set
Tetra test functionality is available for the Aeroflex 3900 Tetra Digital Radio Test Set with the launch of Tetralog Protocol analyser, a PC-based protocol capture and analysis application.
Aeroflex has announced the enhancement of the Tetra test functionality available for the Aeroflex 3900 Tetra Digital Radio Test Set with the launch of Tetralog Protocol analyser, a PC-based protocol capture and analysis application that enables capture and detailed analysis of mobile protocol transactions Primarily aimed at the protocol development of Tetra radios, Tetralog is also an ideal verification/evaluation tool for Tetra mobile developers who are not developing software in-house but purchase protocol stacks from third parties

2.7 GHz radio test system
The IFR 3902, based on the IFR 3901 1GHz radio test set, expands the operating range of the service monitor to 2.7 GHz for both generating and receiving analog and digital RF signals.
Lightweight and portable radio test set
Aeroflex has launched the 3500 radio test set, a lightweight and portable radio test set designed specifically to test vehicle-based radio systems used predominantly by first responders.
The PC-based application used in conjunction with the test set acquires data, analyses it and displays it graphically in the form of Message Sequence Charts (MSC's).
The acquired messages (Protocol Data Units, or PDU's) are also fully decoded to produce text files of the Information Elements (IE's) contained in the messages for display, storage or printing.
System providers will also find the facilities available useful in evaluating and verifying correct operation of a given radio type to be used on a system.

Economy mode for radio test sets
Aeroflex has announced the availability of its new Tetra Energy Economy Mode (EEM) option for the popular Aeroflex 3900 Series of analog and digital radio test sets.
Data capture is straightforward and is performed by simply connecting the mobile to the Aeroflex 3900 via a RF connection and selecting MS test on the 3900.
In this mode the test set simulates a Tetra basestation.
The required Trunked Mode Operations (TMO) to be logged and analysed are then carried out under the control of the radio test set.
This is known as "Active logging".
As capture occurs the data is transferred to the PC via the serial port connection on the test set for immediate analysis and display.
Another mode of operation that allows for the capture and analysis of Tetra Direct Mode (DM) signalling is included and in the case of Tetra basestations a mode to allow capture of basestation signaling close proximity, off-air.
This latter is known as "Passive logging".
The 3900 Digital Radio Test Set with Tetra options gives users full flexibility to tailor Tetra test applications to their own specific requirements.
Incorporating all the features required to carry out both RX and TX parametric measurement, it also includes extensive call processing capabilities compliant with the Tetra radio standard.
This ensures compatibility with the wide range of Tetra terminals now in existence or that are currently under development.
The Tetralog Protocol analyser is available immediately to order and has a 2 week delivery lead time from receipt of order.
