[time-nuts] 4 channel 1 Mhz - 25 Mhz distribution amp

I finally gave up trying to find a 50 ohm distribution amp I liked and wanted to pay for, so I built a simple 4 channel one that uses either a Linear LT1365 or an Analog Devices AD8044. It has an ac-coupled input and transformer-isolated outputs. I took care in the layout to keep trace lengths

I've been thinking about building something like this for some time and I would be interested in seeing the schematics layout. please do post them! thanks -eric On Sun, Jun 7, 2009 at 9:06 AM, wjew...@quackers.net wrote: I finally gave up trying to find a 50 ohm distribution amp I liked and

Dick, The Manuals Plus website lists several manuals for the CSC model DC200B/BR. Don't know what the differences are between the -B/BR models and the -C model, but sometimes the differences can be small; perhaps small enough for you to diagnose your problem. Go to

Per request, I've put the info up on my ftp site: ftp://f...@quackers.net:f...@ftp.quackers.net/ Pick up DistAmp.zip. Also, read the ReadMe! It explains how to actually look at the board layout. I'm using it to distribute my 10 Mhz GPS-based standard (Thunderbolt) to my spectrum analyzer,

Re: [time-nuts] Datron reference circuit error

Bill Just noticed in passing that the equivalent circuit of the LTZ100A shown in the Datron reference at: ftp://ftp.quackers.net/DatronRef.PDF is incorrect. Linear technology seems to have finally corrected this error in its latest data sheet for the LTZ1000. Bruce

Re: [time-nuts] Need volt-nuts help

Hey Ed, thanks for the tips. The DC-200 has a quite different meter system based on the pix of the DC-150 you linked to. I did find a manual for sale for a model DC-200AR, and have inquired if the 200AR is at all similar to the 200C. If it is, I'm good to go. Thanks, Dick Moore On Jun 7,
