Single-box test set for analogue and digital radio

July 30, 2014 // By Graham Prophet
The 8800 Radio test set from Aeroflex is a high performance, economical radio test system for Analogue AM and FM; and Digital P25, DMR, dPMR, NXDN, and ARIB T98 technologies.

The 8800 is equipped with a large touch-screen colour display, and a new hybrid portable design that provides bench-level test features while maintaining the low weight, ruggedness, and 2.5 hour internal battery required for field testing. It features a measurement range of -140 dBm to 500 W.

The display allows multiple meters and analysis functions to be viewed simultaneously. The 8800 introduces an all new capability known as “Fast Stack”, which speeds access to meters and analysis functions by allowing meters and analysis functions to be stacked and then instantly accessed at the press of a button. Features such as user-configurable Presets and Frequency Lists, as well as Colour Meters with graphical indicators for Pass/Fail results allow ultra-fast test of analogue and digital radios by performing transmit and receive tests over multiple frequencies in just seconds.

For bench-level test applications, the 8800 offers the necessary features and accuracy for mission-critical radio tests and alignments; including a typical RF power meter accuracy of 6% and FM deviation meter accuracy of 3%. Digital analysis capabilities include multiple meters, such as FSK Error and Symbol Deviation, along with advanced distribution, constellation, and eye diagram plots for digital modulation analysis. For DMR radios, the 8800 features an exclusive TDMA power burst profile mask to ensure that the TDMA bursts are within ETSI profile specifications. The 8800 also provides digital audio quality analysis, regardless of the vocoder technology within the radio, using a record and playback function.

The 8800 is also uniquely equipped for field-level test applications. The optional tracking generator provides fast swept measurements for VSWR, Return Loss, Insertion Loss, Distance to Fault, as well as tuning duplexers. Results are displayed both graphically and numerically. It can have an optional “internal” in-line power meter rated at 500 W with 4% accuracy, for site maintenance.

The 8800 is designed with a digital architecture capable of supporting fast automated radio tests and alignments. Aeroflex already offers
