Although it does have a calibration option. Before I moved on, they were working on a 1.

Schematic Symbols for Electronic Components: Learn how your comment data is processed. I have looked at their products since then, still making frequency counters but now up dwtasheet the GHz range.

If carefully layed out, Builds can operate into the GHz range. Side note, I am assuming a Books You Should Read: On all other products, production processing does not necessarily include testing of all parameters.

Q3 is on, the equivalent value of R6 and R7 in parallel becomes the constant-current programming. This is probably plenty good for the home workbench because a glitchy output here and there can be ignored.

Very Simple PC Frequency Counter Works Up To 100MHz

The high or the low is going to be 1 second each and use that to gate the counting. You are commenting using your Facebook account.


In fact at MHz, he is pretty much always violating the specified hold requirement because he is sending a 5 ns positive pulse when the hold time is 10ns, regardless as to the PPS source.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of. At best you can do is to gate the timing. A high-to-low transition on the clock CLKI input increments the counter. But on the bench I use one of my old HP counters. The oscillator configuration allows design of either RC- or crystal-oscillator circuits.

Cheap glue logic has now advanced to a stage at which it can be done instead at commodity prices, and we like that. Home – IC Supply – Link.

If you have much longer chain, divide it up again with a MUX so that the counting can be faster. Dec 22, 5 0. There was a time when a project like this one would have required multiple integrated circuits including a probably quite expensive purpose-built prescaler.

The magazine followed with endless frequency counters, and over the next few years the 15 or 20 MHz upper limit for the basic counter slowly moved up as new families of TTL came along. With the RC the oscillator is at about 4.

HC stage cd CD equivalent. Dec 26, 6. Dec 26, 9. Dec 26, 5. In this teardown we will look at a Robotic Floor Cleaner which uses “electrostatic forces” to remove dust and can clean a room with its “intelligent” obstacle navigation.


Timer – Posted by Bernard in forum: I agree that there are more complete ways to do this if you start over.

Though those prescale by some binary number, not a neat ten that makes it easy to use with an existing frequency counter. Very similar to a chip, but allows for programming both time constants on time and off time. Transistors This two-article series presents an overview of circuit symbols and also provides some information on the components themselves.

Nov 30, 18, 9, Well I was thinking of the HP we had where I first worked, that cost, as I recall being told, over two grand in Jan 6, 3, 1, If you really go down this road, you are playing chase the metastability.

Email required Address never made public. This device datqsheet pin equivalent to the CD No heatsink was needed but they were hand-picked by individual performance testing as were the FET input transistors. I usually use a to drive a relay for power applications, datxsheet this is not always datasheef.
