However if you can share with me your EEPROM content (from 0x0800 to 0x0FFF) I'll be very grateful!! Now I need to recalibrate my counter again but I'm still interested with activating the Power Meter. Let's try together if you agree :) --- End quote --- Hi Guile, I figured you had already done something similar, but I thought I would leave the code here for others in the future :) I'll dump our the calibration data for you over the weekend. Hopefully it matches the memory range you expect. Mine is a 575, not a 545B however... If you haven't seen it, here is another person adding the Option 2 power meter.. http://www.simonsdialogs.com/2014/09/eip-545a-microwave-counter-power-meter-upgrade/ I was planning on documenting and sharing my progress on the upgrade, so more than happy to work this out together :) Cheers, Ash. |

I'll be very happy if you can provide me this dump. Indeed I'm planning to repopulate my EEPROM with calibration from other meter and recalibrate it up to 8Ghz for now with the equipment that I have. Regarding to the power meter, yes Simon is a really nice guy. First I've bought some programmed EEPROM from him but when I had my Error 40 failure and that I had to open my meter I've realized that our CPU board were totally different (shame on me). Thus I've a complete set of programed EEPROM for 548A if someone is interested with (just MP). This meter is really confusing as both the SM of 545A and 575B manual are describing the same A105 CPU Board that I have (2020215) which is totally different from the one described by Simon and from the picture found in the EEPROM zip file available online. Thus, regarding to 545B I need to find a way to activate the power meter (removing the Error 13). I'm wondering if computing the correct checksum like indicated by 545A SM would suffice to activate it? Cheers Guile |

For Opt 02 activation you already know the modifications to A107 board to add missing DAC chip and remove/install components as explained by douardda, yes also the R40 has to be removed. Give me your data in EEPROM locations from 0x0800 to 0x080F and I'll try to suggest the possible modifications for option activation :) |

I'll MP you my dump tonight when I'll be back home :) By the way I've read again this entire thread (and my apologies to Douardda as I didn't want to flood his post with my problems) and it appears that I also have FW Special W98 (or something like that). Thus recently I started to have the frequency offset (-160kHz) and resolution low activated at startup which I didn't have before. Thus if I understand correctly this information resides also in the EEPROM, am I right? As this problem appeared before Error 40 happened, I'm wondering if this was not an annunciation of a problem with the EEPROM? Thus if someone with the same CPU board and same FW (and same EP1 545B) could also send me his dump, maybe I'll be able to compare and select the best data to compensate the lost I had in my meter ;D. Finally, going back to my EEPROM dump, you mentioned that 600Mhz calibration was for special options. It looks like this option is related to the FW I have, right? Thus maybe 6.5Ghz is also part of this special calibration? Thank you! Guile |

It doesn't appear to have any non-volatile ram, at least in that range. I guess my entire memory map is different that I have found in the available service manuals.. My EIP 575 has A105 (CPU) board part number 2020195 (-01 hand written) if that helps at all.. probably not.. Maybe HighPrecision can shed some light on the older '575 units? The model and serial numbers read: Mod: 575 CCN 1802 SER: 00671 Ash. |
