Greetings I have a Tek TDS694C I will be selling, and I'd like to demo it's high speed performance by showing it detecting a rise time - I'm trying to remember exactly what that is - somewhere in picosecnd range? Is there a chip which will show a fast rise time? I believe they use some kind of high speed fpga? thanks in advance jb

Bought a couple of oscilloscope probes today to replace those damaged/lost. They don't fit, because the plastic surround exceeds the specified diameter for a BNC plug. My scope has a hole in its front plate to accommodate a standard BNC plug, but it's not big enough for this oversized plastic variant. This probably saves several cents per probe, but created a problem I didn't need. ...

Conventional samplers for home brewers usually go to 1 GHz. The SD-32 sampler for the Tektronix 11801C mainframe goes to 50 GHz. The HP 110GHz oscilloscope costs around $1.3 Million USD, with a 10-bit resolution. Very impressive, and very expensive: https://www.youtube.com/watch?v=DXYje2B04xE I have invented a new sampling technology that promises 160 GHz bandwidth, yet is affordable to ...

I use a PC oscilloscope from UK company Pico Technology. An old model called ADC-200 which is no longer supported but meets my hobbyist needs well. It connects to a USB socket on my XP PC via a special adapter, the 'Pico USB Parallel Port'. Suddenly, it's stopped working. The Picoscope software tells me 'The ADC-200 is not connected. Looks like the adapter is broken. (Its LED is not on and it...

I've many times made ad hoc sniffer coils for hunting out EMI & found them invaluable. This more-refined implementation came across my radar this morning, and seemed worthy of revisiting for the group. The EMI Sniffer Probe is a small pick-up coil for probing high-frequency magnetic fields with an oscilloscope, featured in Jim Williams' classic AN118, Appendix E. https://www.analog.com/...


RS232 decode routines from raw scope data?

Is there a simple Windows or Linux program that can decode serial data out of raw data from an digital oscilloscope? My old logic analyzer does not have any serial data decoding and neither does my scope. So I'd need something that can take in the ADC raw data, I set a threshold to turn that into H/L digital values and the software would fish out the data words. Not sure if it even exis...

Hi Just wanted to share this I just downloaded the open source gain/phase analyzer for the Pico scopes https://bitbucket.org/hexamer/fra4picoscope/wiki/Home It works great So use you Picoscope to get a gain/phase analyzer for free, or if you can use a USB scope also, then spend 129 USD for the cheapest Picoscope with AWG: https://www.picotech.com/oscilloscope/2000/picoscope-2000-...
