Description
 We've all seen different models of portable scopes, meters, and scope/meters. We've also seen the price tag! Unless you were a field tech with a good sized test equipment budget, they were out of the question. These Velleman "Personal Scopes" have changed all that, and put a hand held digital scope within reach of the hobbyist, student, and technicians! As I'm writing this, I personally remember when I shelled out a couple thousand dollars for my first Scope Meter! And now you can buy one of these for several hundred dollars...with more features besides!
With today's technology, merely measuring voltage isn't enough. Whether you're an auto mechanic looking for electrical noise, working with audio equipment, or a student working on lab projects, a scope is a must! Now, instead of carrying around a digital multimeter you can actually have your own personal scope at about the same price! And besides a scope, the display has a DVM readout for dBm, dBV, DC, and True RMS! Frequency readout is also displayed on the screen through markers. Plus, the scopes have two memories for digital signal storage! That's right, we said it's a storage scope!
 The HPS40 also includes an RS232 serial output! At the push of a button you can capture the screen display to any PC connected to the serial port.
The scopes run on 5 standard AA Alkaline batteries (not included) which provide up to 20 hours of use. Rechargeable AA NiMH batteries can be used in place of standard Alkaline batteries and will be automatically charged with the AC power adapter provided.
Each scope comes with a custom foam lined, high impact carrying case, set of high quality scope probes, AC power adapter, and comprehensive user's manual. The HPS40 also includes an RS232 interface cable for PC connectivity. If you're working with electronic circuits, automotive applications, audio and stereo applications or any other type of electronic applications, the Personal Scope is for you...at a price that can't be beat!
