Re: Terry's DRSSTC and HFBR optics

Hi Terry and List,
Back at the lab now and looked up some of the packing,
it is from Allied Electronics. Web site on packing was www.alliedelec.com so
I guess you can look and compare. I started out first with the slower digital
receiver and transmitter packages, the evaluation kits. Did not take too long
to learn I needed the fast analog units but the nice part of having the evaluation
kits was I ended up with pre-made cables of the right lengths. As we have an
account with allied at work it is easier to cut the PO, order what I want and just
pay the office when they come in. I did find that some of the analog (Dc through RF
outputs) were special order depending on the light band they were in. Using the
analog let me get data without so much concern of the minimum signal threshold.
In darkness below threshold even for the analog, one must watch for false switching.
It is good to have access to nice optics though and I am happy these are available.
It would be nice if they had a line at the 427 nm end.

Hi Terry,
Yes the HFBR series are nice. I've been using the analog 125 Mhz units in 2 optical bands here on the plasma frequency receivers. They seem to make a good product, meeting spec and then some. Lately been using a PMT and 72 mm 427.8 nm filter as well. You would get that spectra from a TC ionizing the N2 in air. As I remember on the data sheets (PDF files) they speak of inverted outputs on some of the models, have a bunch of analog and digital units here.

Do you know of a good place to get the Agilent HFBR stuff? Like everything, Newark always has it, but their prices and shipping add-ons for little orders are pretty steep!.
