Test and Measurement
Day Sequerra M2.2R
Day Sequerra has updated its M2.0 HD modulation monitor, adding some nice and very useful features. I first reviewed the original M2.0 in Radio magazine in May 2006, and the new M2.2R model is an attractive piece of test equipment that will likely go in your facility where it can be seen by you and others.
Digital Audio
With analog, engineers know how to measure levels, frequency response and distortion to gauge the audio performance. Unfortunately, digital audio changes all this.
Whirlwind AES Qbox
When a station changes to AES3 or S/PDIF digital audio, the availability of easy-to-use, rugged and portable test equipment declines greatly.
Audemat-Aztec Goldeneagle FM/HD
With HD Radio, stations at minimum need to monitor the main channel audio. But there's also multicasting, PAD and funny initials like DAAI and QI that tell volumes about the signal. The big question is how to acquire all of that data.
Sign Off
The computer hard drive is 50 years old this month. Take a look at the IBM RAMAC, which held 5MB of data and was the size of a refrigerator.
Trends in Test Equipment
If you had the opportunity to equip yourself anew for the year, which pieces of equipment would make your core list?
Beyond These Walls
When the work takes you outside the studio.
Prism Sound Dscope III
Doug Irwin put the Dscope test set through several tests of his own.
Cold Heat Soldering Tool
You have seen the TV spots for the latest and greatest products that we just can't live without. Recently there was one that caught the eye of our reviewer. It might have caught your eye as well.
Proving Performance: Test and measurement
While the basic skills of evaluating system performance are still in place, the tools and the methods used today are changing significantly. Digital signals require analog tools, but you can't neglect the analog elements either.
