| Agilent PNA E835xA with 85092 ECal, Problems |

To work around this, we can try and use the RAW mode. "NI-VISA USB RAW mode supports Interrupt, Bulk and Control data transfers. Isochronous transfers are not supported. " Still using the wizard but selecting other rather than the identified connection, then manually entering the VID/PID. This will create the INF file, which you can then just copy into the Windows/INF directory. Windows 10 requires all the drivers to be signed. They have Inf2Cat & signtool which could be used to but MS provided the advanced boot menu what allows you to disable driver signature enforcement. After installing our driver and rebooting, the system is back to normal. |

Windows reports the new driver and running the Device Monitor, it now reports the ECal. |

I then wrote a simple program to try and get the ECal to respond with anything. This was a total bust. I am not aware of any tools outside of the PNA that will communicate with the ECal. I can't seem to run the Agilent software in a virtual box without the actual PNA hardware attached. Normally, would just install a sniffer on the target but with this thing being so old, it would mean finding a compatible sniffer that actually works.. Maybe something like this could be used: https://github.com/ataradov/usb-sniffer |

Have you tried the secure erase tool running on a PC? I've been able to backup(and I believe restore) the entire writable flash region with that. The tool is called ECalWipe. |

Installing their drivers under Windows 10, and running the program, it does talk with the device. I tried the ALL data dump and searched for the end. Seems there is no user data (all 0xFF), which is what the PNA reported. Are you aware if anyone has decoded their dat file format? |
