Re: What kind of connector is this?

Meanwhile I have received the shipment. For the case someone will discover a connector like this one: I can confirm now, it is truly a Hirose adapter from the 12-pin series. The photoed male conector and the ordered female 12-pin Hirose connector do exactly fit together. As the connector is pretty s...

Re: A semi-DIY preamplifier for radiation detectors

Very interesting work Rich!

Just for the stupid guys. How much MHZ/ nanosec rise time is your from-scratch-preamplifier?

Re: Spectrum Recorder PCI-E Card?

Just one final remark from my side. I've figured out, that my Hantek digi-scope effectively is a Linux computer. Thus, may be it is - on a maker basis - possible to construct an inexpensive "very high frequency recorder" by porting the Hantek Linux scope solution to a more potent mainboard with a PC...

Re: Spectrum Recorder PCI-E Card?

After in depth study of Chris answers there is only one thing left:

Saying thank you to Chris for his imho high quality answer and to all the others, who mentioned a lot of major ideas before.

Re: Spectrum Recorder PCI-E Card?

Thanks for your insights into physics topics. I do not doubt, I am maybe sometimes like a little child in these physics things, as I am a statistician (not a physcists). However, on the other side it may also be interesting for you physicists how a statistician is planning to deal with the piled up ...

Re: Spectrum Recorder PCI-E Card?

The following picture from wikipedia aliasing article shows a sine funtion, that is undersampled: AliasingSines.svg.png So, if I sampled a periodic sine function with 2 or 2.5 times its frequency (to avoid aliazing), would that also invoke, that there are enough samples (data points) to reconstruct...

Re: Spectrum Recorder PCI-E Card?

Just for info: I've got a 250 MHZ 1GSample/s digital oscilloscope with data export functionality. However the maximum #samples is very limited. 48k samples or so. Ok, lets do some digestion of your advices now: You say, to sense a periodic signal (e.g. sinus signal) a sample rate of 2,5 times the fr...

Re: Spectrum Recorder PCI-E Card?

You're absolutely right John, if I wanted to count in real time. But that's not the case! Instead I want to record a longer period to a fast PC hard disk (a SSD) and to analyze the recorded data much more sophisticated by a statistical software for hours, days and weeks to solve the piled up amplitu...

Re: How to figure out the specs of old Rigaku scintillation tube probe?

Some further thoughts from me: The external 5 pole connection of the preamplifer board fits to the preamplified positive going signal scheme in https://www.crystals.saint-gobain.com/sites/imdf.crystals.com/files/documents/scintillation-operating-manual_70421.pdf page 3 and 4 (page count as labeled) ...

Re: What kind of connector is this?

Thanks John. Maybe it is not a LEMO 12 pin connector, which looks like this: LEMO-3B-connector-12pin-Plug-socket.jpg But your hint brought me on the right track. I guess now, it is a Hirose 12 pin connector Hirose-Connector-12-pin-plug-HR10A-10P-12P.jpg I've ordered two of these now to test it out.
