You get the ADC, the memory controller/triggering, the sample memory, and then the SoC running the display and stuff. We've got good availability on SoCs for the application software, ADCs (to some degree), and memory.... so it's the triggering/channel timing/memory controller ASIC that's the real missing link in my mind. --- End quote --- This is why many scopes use a the Xilinx Zynq as it combines an ARM applications processor and an FPGA. More than powerful enough for decent performance entry level scopes. |

You can't just say "Give us money to make a scope ASIC and we'll work out the details later". |

People used to be excited about 20MHZ analog scopes but now that is considered a useless toy scope. --- End quote --- Yes, but now you can get hacked 200MHz 4 channel scopes for under $400. Anything much higher bandwidth and you reach the usable limit of passive probing technology. |

I've unlocked this thread because I think it's hugely interesting, please play nice. |

The first thing you need to do before even considering such an ASIC is to fully itemise the BOM cost for current designs and find out how much you can actually save with this magical custom ASIC. You might very well find it's simply not worth it and doesn't offer enough advantage. And I'm talking BOM cost down to every last screw and knob. If you haven't done that then the whole thing is a folly. |
