Several people on the list were helpful in my search for what turned out to be a Grayhill clip for use in a component test fixture - Thank You! A couple people requested a photo of the finished fixture. I have added it to the photos section of this list today. Title is "Component Test Fixture using Grayhill clip". Sorry about the poor photo quality, but should be adequate to give you an idea of what it looks like. A few words of description. I built it for use both with an AIM 4170 impedance analyzer and my benchtop Agilent DVM, both of which allow nulling and calibrating out strays in a test fixture. DC and low frequency with the DVM and up to over 100 MHz with the AIM. I use it mainly for quickly checking component values of resistors, inductors, capacitors and diodes. The fixture accommodates three types of component leads, axial (Grayhill clips), radial (DIP and header socket strips) and SMT (SMT pad and spring clip). All three work well. Also added some binding posts, but don't normally use them. The red momentary push button switch is used when nulling out the lead resistance for resistance measurements. The Grayhill clips are awesome. Several styles are readily available from Allied with reasonable shipping and extremely fast delivery. The ones I used were Grayhill PN 02-0. They have a model 02-1 that has a banana plug attached to the clip so that you can directly plug it into a DVM test lead socket if you want to eliminate building a fixture. I used a small Hammond plastic box for the body of the fixture. 73 Craig AC0DS

Do you have a better part number? Charles AE5EW

Good Morning Charles . The Grayhill PNs in my post are correct. The Allied stock #s are 948-1000 for the 02-1 and 948-7397 for the 02-0. The Grayhill website (www.grayhill.com <http://www.grayhill.com/> ) will also show other stocking distributors. Look under the "accessories" section. Grayhill has a very good pdf datasheet for the entire series of test clips. Unfortunately, I couldn't get it to link this morning. You will probably want to look at this before you make your final selections, so I suggest trying their website later. 73 Craig AC0DS Craig D.

Odd, I had to do a search on 'test clip'. I DL the datasheet. The ultra miniature looks like a good candidate for RF tests. Charles AE5EW
