A system and method for testing radio coverage of a land mobile radio system. The system configuration generally employs a fixed unit, a mobile unit and the two-way radio system (not part of the invention) subject to testing. The test system and method are compatible with any land-mobile radio system (conventional, trunked, using proprietary or standards-based protocols, FDMA or TDMA) operating in any frequency band. One of three methods may be selected to perform testing at any one time: continuous testing, grid testing or receive-only testing. In the continuous and grid modes, both the talk-out and talk-in paths are measured. Test results are recorded in a computer file after being converted to a digital format, and are compared to an original “reference file” via the Perceptual Evaluation of Speech Quality (PESQ) algorithm as defined by ITU-T standard P.862. The PESQ output is then converted to a Delivered Audio Quality (DAQ) score by application of an empirical set of weighting factors to certain of the PESQ parameters.

Disclosed is a fluid testing device which utilizes a small, cross-section fluid interface to separate a test fluid chamber from a drive and measuring chamber. The test fluid chamber contains the test fluid and a paddle-type fluid test assembly. The drive and measuring chamber contains a second fluid and assemblies for moving the paddle and for determining the resistance movement.
