Marko, don't be sad, if you are having trouble getting a specific part for a specific project you are stuck on, I'm sure other forum members can help. I'm not sure if the argument "Give me a DEIC420 because WaveRider has one" would work though :P
Steve, even if I had a bunch of those I wouldn't have anything to do with them apart from sell them, so only kidding :D
But I'm sure it makes some forum members jealous (BP)?
Also, apartment workshops FTW! Mine is in the corner of the kitchen (the item underneath the scope is the fridge)
You guys dare to think you can pwn my disarrangement so easily? Creative mess FTW. :p

You have the same scope as me I think my scope has a bad connection somewhere though, sometimes I lose the signal (or well it gets *very* attenuated). Both channels do this every once in a while. But I guess its pretty easily fixable if I'd just could get the energy to open the scope.

Don't worry BP, the 27.12MHz goal is not on my list yet. I intend to use the transistor/driver for a 13.56MHz setup first. (Probably a class-CD type amplifier without ZVS..I need to do some simulations first to estimate safe dissipation levels).. The data sheet for the RF power transistor indicates a switching time of 14ns..good enough for 13.56MHz, but for anything above 15MHz or so, dissipation could be a problem at sustained high power levels. IXYS sell a version of this transistor in an RF flat pack (much less parasitic lead inductance) that switches in 4ns.....but they are very expensive..
Steve, Marko: I love creative messes.....but I'm a married man who likes to maintain the domestic tranquillity..... My mess needs to be confined to the "lab"... My wife is very understanding, though...
The spectrum analyser set me back 2500 euros. It is spot-on frequency. I compared its measurement results to a new Agilent PSA 4443 series spctrum analyser and it is still fairly well calibrated.

WaveRider, can i have all your gear when/if you die ?
Aw, what are you sayng hfsstcfreak...

Yes, I had it lose contact on the BNC's few times, usually when I would pull the probe cables too much. Open it and check the connection with multimeter if it's a big problem.

Yay I have some little tray organizer things just like those for electronic parts, but most of them are not filled. Btw, why do you have a vacuum tube on that top shelf? What if it fell off?
