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

technician! As I’m writing this catalog copy, 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 DVM readout for dBm, dBV, DC, and True RMS! Frequency readout is also displayed on the screen

through mark-

ers. 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 cap-

ture 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. Rechargable AA

NiMH batteries can be used in place of

standard Alkaline batteries and will be

automatically charged with the optional

AC power adapter.

Each scope comes with a custom foam

lined, high impact carrying case, set of high quality scope probes, and a 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 elec-

tronic applications, the Personal Scope is for you...at a price that can’t be beat!

RF1

RF Probe

YOUR OWN PERSONAL HAND HELD SCOPE!

The RF1 is a very sensitive RF detector probe

that connects to any digital multimeter and pro-

vides a DC voltage output from weak RF sig-

nals. This allows very easy tracing of low level

RF signals that a counter can not pick up. Wide

frequency coverage of 100 KHz to over 1000

MHz lets you track down most any problem in transmitter chains, receiver stages, or even complex PLLs.

Uses exotic, low barrier microwave detector diodes to give exceptional sensitivity which can see signals down to microwatt levels! A

great low cost way of checking for RF. Fully assembled and tested, and includes standard banana plugs for use with any standard VOM, DMM or volt-

meter. If you need to measure RF and don’t want to spend big bucks, here you go!!
