Project 25


FREEDOM Communications System Analyzers provides
comprehensive test support for Project 25 systems.

FREEDOM Communications System Analyzers allow full testing of P25 subscriber radios and infrastructure. Options allow testing of P25 Phase I and Phase II systems.

A core set of features that allow testing of P25 Phase I systems. Support for measurements of C4FM and complex modulation formats allow testing of subscribers and infrastructure. Measurement of modulation fidelity lets you know the quality of your transmitter and Error Vector Magnitude (EVM) measurements allow advanced measurement of simulcast base stations. The inclusion of P25 Standard test patterns such as the 1011 Hz Tone and O.153 pseudorandom sequence permit testing sensitivity of a P25 radio. Also included is capability to enter signaling information and decode voice frame information allowing users to test proper configuration of a radio or test a live conventional repeater.

The P25 trunking option enables the R8100/R8000 to become a base station emulator and trunking controller. Default Frequency plans for the VHF/UHF, 700 MHz and 800 MHz bands are provided. The user may modify these plans as needed for channel bandwidth, duplex offset and the bands base frequency offering a complete and comprehensive test solution for all P25 trunked systems. Test functions include: Control Channel Idle, Registration Request, Registration Grant, Traffic Channel Request/ Grant, Voice Channel audio paths, including encryption if fitted, with
Voice Loopback, Incoming call alert tone, and Voice call (1011Hz Tone).

Our APCO P25 Phase II option offers the most complete test suite of any instrument in the industry. It features a comprehensive array of modulation and analysis tools for both H-CPM and H-DQPSK modulations, including:
