Aeroflex announced additional test and alignment capabilities for Motorola P25 APX series radios and for EF Johnson Viking VP 600 series P25 radios on the Aeroflex 3920B digital radio test set this week (5 August 2014). The new test capabilities focus on Phase II transmit and receive tests.
The Aeroflex automated test and alignment procedure provides fully automated test and alignment the radios without the need for user interaction. This test system ensures consistent and reliable tests and alignment to manufacturer-recommended specifications and to industry standards, ensuring proper interoperability and a uniform standard of performance within the radio’s network technology, Aeroflex stated.
Phase II modulation is becoming more prominent in P25trunking systems and uses two different modulation types for uplink and downlink. This application can perform Phase II tests even if the radio is not currently being used for that application. This ensures that the radio will work if the system architecture changes in the future and where Phase II operation may be required.
Mike Fortna, senior product marketing engineer, Aeroflex, said that the 3920B provides an advanced method for repeatable and highly accurate test and alignment for both the Motorola and EF Johnson radios that requires minimal technical interface.
Aeroflex said that since the 3920B provides fully automated tests and alignment processes, Motorola and EF Johnson dealers and end users can now utilise their technical resources to provide higher value services.
Both the Motorola APX and EF Johnson Viking 600 Auto-Test II options are available now. To take advantage of this new feature, the 3920B requires Option 220 for Phase II operation. The Aeroflex 3920B has a delivery time of eight weeks upon receipt of order.
