Are there any typ % utilization specs for the Spike application running on a typ i7 Quadcore 3.5GHz 8GB Win7 x64 computer w/ BB60C?
I see videos showing good Spike update GUI rates, but I’m wondering the extent of CPU resources needed for this processing and if the CPU fan is screaming.
I know FTDI comm is not unreasonable, but unsure of the Cypress USB3 silicon driver requirements and/or Spike GUI processing demand.

For the CPU type you mentioned, you can expect CPU usage between 5-20% depending on which type of operation you are performing. The real-time spectrum analysis mode is going to have the highest CPU usage, followed by zero-span and modulation analysis operations, followed by standard spectrum analysis. For standard spectrum analysis we have an option to introduce a delay between screen updates which slows down the update rate and lowers CPU usage.
