Re: problems with an E4407B spectrum analyzer
|
Hi, In my case I did not have the B72 option. I had bought and installed the missing circuits on the flash card and repositioned a jumper. I also used an old PC under XPpro to create the diskettes. But during the installation there were difficulties with the loader diskette and another diskette during the second attempt. I had recreated another diskette kit and everything had worked fine. Don't worry too much, you will eventually get there ? Yves ? Hi guys I am trying to learn about the ESA 4407B analyzer. I have "bricked" a unit. I pressed ESC + view/trace key during powerup. So the EEprom is erased. I need to enter new firmware now. But it will not take my floppy(s). It starts to blink the light on the floppy but nothing then happens. Unit has option B72 so the EEProm size is 12Mb to store the firmware. The unti was working before the upgrade. What I am doing wrong how can I load new firmware.
