Anritsu reckons its ME7842B tower mounted amplifier test system (TMATS) will dramatically simplify testing of multiport TMAs used in 3G mobile systems by orchestrating final test measurements in under 30s The TMATS combines Anritsu's Scorpion vector network measurement system (VNMS), a flexible multi-port test set and easy-to-use Scorpion Navigator software, and can be easily integrated into existing test executive environments

Bluetooth tester runs the lot in 10 seconds
Anritsu has introduced the MT8850A tester to offer manufacturers of Bluetooth modules comprehensive, one-button testing traceable to national standards.
The ME7842B's flexibility is provided by the design of the test set, which allows thorough testing of TMAs with two to five ports via a single connection.
This increases manufacturing efficiency and productivity compared to other testing methods that require multiple test stations.
For added flexibility, Anritsu has designed TMATS with two auxiliary paths, allowing the system to make custom measurements such as adjacent channel power ratio as well as meeting future requirements.

Anritsu has introduced the MP1580A, a portable jitter analyser for 2.5/10Gbit/s SDH/SONET fibre-optic transmission systems.
With Anritsu's Scorpion Navigator software, TMATS provides engineers with the power and simplicity to see the true performance of both current and future TMA configurations.
The ME7842B provides the necessary paths for S-parameter tests to be performed with clear pass/fail limit lines, allowing the rapid determination of insertion loss, return loss, ripple and out-of-band performance.
Active measurements, such as gain, noise figure, compression, harmonics, intermodulation distortion (IMD) and adjacent channel power ratio, can also be performed.
In addition, the Navigator software's intuitive user interface enables the user quickly to make productive measurements on most TMA configurations.
The accuracy and measurement speed of TMATS complement its flexibility.
The test set performs S-parameter measurements with +0.1dB accuracy and has IMD accuracy of +1dB maximum (above -60dBc).
It can measure noise figure of less than 0.5dB and gain compression as high as +16dBm.
Depending on the test requirements, the TMA measurements can be performed in minutes, and in some cases seconds, instead of hours.
By typically conducting tests faster than other test systems, TMATS dramatically reduces the costs associated with manufacturing the variety of TMA configurations.
Covering the 10MHz to 6GHz frequency range, TMATS handles a maximum TMA output power level of +20dBm and has a typical dynamic range of 80dB.
The system can provide an input power range to the TMA of 0 to -85dBm, with typical port power accuracy of +0.1dB when using an optional power meter.
