In other words the yellow egg product. :-DD --- End quote --- Do you have a sense of the magnitude of jitter you'd like to look at? It may be difficult to get below 400 fs RMS jitter floor with discrete components. --- End quote --- by PM... |

We have just released v2.6.2 of the software and v14 of the firmware. The main additions are USB firmware update support, and significantly (3-10x) faster sweep rate. The firmware has been significantly rewritten, and now natively supports Nmin up to 250 and K up to 500k, with optional 16-bit CDF return format and built-in monotonicity correction. For TDR/TDT applications in particular, sub-2-second sweep rates are now possible with good time resolution and accuracy. We have also added the ability to display time in distance units for this purpose. For single-valued signals at the fastest sweep rates, there is still a remaining factor of ~3 in theoretical speedup. This requires a new mode of operation (send timebase start/stop/step and return an array of voltages), which we plan to implement in v15. |

I downloaded the latest firmware (second file you provided) along with the latest software. Running the software without the new firmware appears to act normal. After programming the new firmware and power cycling the scope, the software lists the scope and appears to connect. It would not start sweeping like expected (no signals applied). I then used your software to check the device info. SN and firmware display 0 (see attached). Using my software, I am able to connect to the device. Reading out the status I get the following: Info: 14 9 0.0000 0.0000 0.0000 0.0000 1.0000 1.0000 1.0000 1.0000 ID: GigaWave 6400 Digital Sampling Oscilloscope So it appears to have the rev 14 firmware and knows it is SN#9. I then attempt to sweep and it appears to crash the scope. I can no longer get it to respond to any commands. Power cycling the scope, I am again able to connect. Attempting to sweep once again hangs it. Let me know how you would like to proceed. |

We have just flashed the firmware file we provided to you onto a test unit, and were able to use the software without problems. To confirm, did you update both the MCU and FPGA firmware? The v14 FPGA bitstream can be downloaded from our firmware upgrade guide (software page on the website). *** Directly linked below for convenience: https://gigawave-releases.s3.us-east-2.amazonaws.com/GigaWave_6400_FPGAbitstream_v14.bin |

I was not aware the FPGA had been updated as well. |
