Buffer Memory

Postby torpedoman » Fri Oct 15, 2010 3:16 pm

Is the onboard buffer memory non-volatile? I work in a classified lab and would like to purchase a 6000 series oscope, but I can't have any NV memory on the hardware. Could you please describe the implementation briefly? Thanks.

Hi the memory is volatile, it is RAM and as such does not retain the memory when switched off. You can save the waveforms though as psdata files or in other formats.

Is there ANY non-volatile memory on the hardware anywhere, i.e. flash for FPGA configuration, processor serial boot flash, etc? Is there software that needs to be updated on the hardware? If so, how is it done? Does the hardware poll the PC for any information?

Does the data go in 1 direction, i.e. A/D -> RAM -> Data Compressor -> USB to PC, or does the hardware take any info from the PC?

I need to attach this to a Secret PC, and the IT crew needs to know this info before they sign off.

There is non-volatile memory in the device, however this is only used to store the calibration date and device model number and serial number and some other info about the device. You cannot adjust this and it does not poll the PC. The FPGA itself is volatile and is programmed when you run the software via the driver file on your computer.

The PC can poll the device only. So in a nutshell there is nothing in there to be concerned about. I hope this helps.
