Use a FET input probe is the quickest solution. These are higher impedance and very low capacitance probes. The only drawback is cost. Derek Koonce

For the fastest breadboarding effort, have you gone to the National Semiconductor WebBench site?

I would like some suggestions of how to generate a single pulse for a 40kHz ultrasonic transducer. I would like it to be 150V for 80us to 100us. I have the 150V supply available.
There is a module by Massa that can do this, but they are very difficult to work with to get the basic circuit for...
Two good sources of oscilloscope information - Tektronix and HP. These two manufacturers have done a lot of publications of DSO vs. Analog. Research their web pages and then call a sales rep and ask for the pitch.
Then make up your own mind as to what you really need.
Personally, I got the...
A mentor of mine once commented "If you always want a job, stick to analog and power supply EE." Personally, going the digital route is what most people do. I find analog electronics is challenging and it has opened many doors to career advancement. I started as a development engineer...
What you are talking about is input frequency. This is not a problem since most supplies will convert the AC signal into a DC level using a bridge rectifier. The definition of wide input voltage range would be 90VAC to 270VAC.
Just because a supply specifies a wide operating voltage range does...
You can find a lot of information on SMPS from Motorola, TI, National, Supertex, Power Integrations.<br>

A good, simple primer would be to review the application note AN-H13. This can be found on the Supertex web site - <A HREF="http://www.supertex.com"...
What is the question? If you want precision measurements using a GPS, you will not get it with the satellites while the error government has the errors turned on. Beyond this, you will need a differential GPS system. A good start would be survey places.
I have not heard of a certification as such. I have been desiging magnetics for 15 years and all of the mentors I talked to in the beginning say that the best way to learn is to read multiple books on design methodologies and then develop your own. Beyond this it takes experience and lots of...
The simple method is to use a SSR. These can come in a 5V input to switch on/off an AC signal. Check in the DigiKey catalog or Newark's catalog for the part number and costing.
