Most digital equipment is woefuly lacking in its ability to display why it is unhappy. Luckily, the Digilyzer displays things such as lack of data compliance, bad cables or poor signal quality.
Early solid-state audio spectrum instruments provided limited resolution, but the MSD100 offers a bright, easily read display of stereo separation and frequency dispersion.
This test system interfaces to a Windows PC via a single USB connection. While the Dscope can be rackmounted with the appropriate hardware, its approximate 12" x 9" footprint makes for a good fit with a host laptop computer, thereby creating a portable, no-compromise audio test system.
The improvement of digital devices over analog is also obvious in most cases. But think about your facility: Is the digital improvement as good as it could be?
Modern equipment is stable and reliable, but some things should be checked on a regular basis.
Regardless of the compliment of analog and digital equipment, every station's goal is to maintain a quality audio signal through the entire chain.
Audio Precision has released a special Digigram version of its Application Note for PC audio device performance tests.
Ibiquity has completed tests for its FM IBOC system, and tests for the AM version are currently underway. What interests most broadcasters is understanding the test objectives. At this critical point in the acceptance of IBOC, stations should be aware of the efforts being made to develop a workable and realistic system.
Digital audio has provided radio with a means to deliver a higher-quality sound without requiring significant additional cost.
The explosive use and integration of the AES format in radio broadcast facilities has prompted several manufacturers to get in the game by building test equipment.
At some point in an engineer's career, questions such as How does our signal compare to so-and-so? or, Have we increased multipath along the highway lately?
