The Klippel is here!
I got a package from Klippel today which contained my Distortion Analyzer rack mount unit along with a MI17 microphone, microphone power supply, necessary cables, and literature. I have taken some pictures of the products and attached them below. Just click on the image to enlarge the photo. Note the small size of the DA. It’s dimensions are approximately 19in x 10in x 1.75in and weighs ~6.6 lbs. Given everything it’s capable of, you’d expect it to be quite large but the Herculean power is all nestled in to a small, somewhat portable box.
You can also see in one of the photos the Calibration Data sheet. This particular unit was calibrated about 3 weeks ago and shipped out to me last week.
Below the photos of the items received today you’ll see some sample data. As it turns out, I will also be Beta Testing for Klippel and have such been provided with a pre-release version of their new R&D dBLab software. I’ve only gotten a chance to navigate it for a little bit but so far have found some really nice changes. The pictures highlight particular changes; such as the way the tables are presented, the calculated assymetry in the Bl Symmetry data plots (and the Kms Symmetry data, not pictured), as well as a user-defined distortion threshold in the Harmonic Distortion data set. As I begin to use the software for testing, I’ll make sure to note key features of the new version I like (and, if any, ones I don’t particularly care for).
I have some things to do before I can start testing, but it should be up and running within the next few weeks. For now, enjoy the pics!
New Table Format. One thing I like here is the ability to export the data as text and then dump it in to Excel without losing formatting (ie: you won’t have to manipulate the data within Excel to make it usable).
The TRF Measurement Module (aka: Frequency Response and HD) now allows for a Fundamental Mean to be set in addition to a threshold for distortion. This is particularly useful for quickly spotting where distortion may creep up to a point where it’s likely to be audible (ie: -30dB is roughly 3% THD). Though, keep in mind this threshold isn’t relative to the FR. It’s absolute. At least, as far as I can tell right now.
