Protocol analyser aids development of
Tetra radios
PC-based protocol capture and analysis application enables capture and detailed analysis of mobile protocol transactions.
Aeroflex has added the Tetra test capability available for the Aeroflex 3900 Tetra Digital Radio Test Set to the new 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 a verification/evaluation tool for Tetra mobile developers who are not developing software in-house but purchase protocol stacks from third parties

Deeper analysis for broadband signals
Aeroflex has added a broad array of new signal measurement capabilities to its Celerity CS35000 Series broadband signal analyser and recorder family (BSA).
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 useful in evaluating and verifying correct operation of a given radio type to be used on a system.
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.
