Aeroflex unveils range of new wireless equipment testing functionality

Aeroflex announced the availability of three new features for its digital test set at IWCE 2013 in Las Vegas, USA.

Aeroflex unveils range of new wireless equipment testing functionality

Wireless testing equipment manufacturer Aeroflex introduces a number of new features to its range of Digital Radio Test Systems at the IWCE show in Las Vegas last week.

VSWR (return loss) and distance to fault for tracking generators

First up is the addition of enhanced VSWR (return loss) and distance to fault to the tracking generator functionality of the Aeroflex 3550 Digital Radio Test System. By utilizing the sweep of the tracking generator, the 3550 can measure and display the VSWR of an antenna or find the location of one or more faults in a cable.

The 3550 measures the VSWR of an antenna by transmitting over the frequency range selected by the user and measuring the level of the signal reflected back from the antenna. This is performed with the assistance of a return loss bridge that is connected between two ports of the 3550.

The user can select the frequency range and the units to display the reflected signal level, either in dB (return loss) or VSWR. This measurement is an important indication of the performance of the antenna.

The existence and location of one or more faults in a cable can also be determined with the 3550 tracking generator. This sweep, with the assistance of a resistive power divider, combines the signal transmitted by the 3550 with the reflected signal, and then through special signal processing, produces a plot that shows the precise location of any cable faults.

This plot not only helps determine the location of the fault, but also the severity. A cable fault determination is critical when trying to determine where the problem lies, in the radio or the antenna/cable system.

Automated tests and alignment of Harris P25 series portable radios 

Aeroflex’s second announcement was for the addition of support for Harris P25 P7300, P5500 and XG-75 Series portable radios to its expanding capabilities for the Aeroflex 3920 Auto-Test II system.

The application provides automated testing and alignment to provide a new level of consistent repeatable results. Both dealers and end users can use this advantage to decrease the amount of time spent on the tedious task of testing or aligning radios. Alignments can be performed in less than 10 minutes and testing of primary functions can take much less time.

With a proven track record for speed and accuracy, this application uses the precision instrumentation within the 3920 to quickly perform test and alignments to manufacturer specifications. An exclusive cable correction feature ensures that power measurements are always correct.

Automated tests and alignment of KNG portable command series radios 

Finally, Aeroflex also announced the addition of support for the RELM Wireless KNG portable command series radios to its expanding capabilities for the Aeroflex 3920 Auto-Test II system.

The application provides automated testing and alignment to provide a new level of consistent repeatable results. Both dealers and end users can use this advantage to decrease the amount of time spent on the tedious task of testing or aligning radios. Alignments can be performed in less than 10 minutes and testing of primary functions can take much less time.
