Mine too, just arrived with empty nvram, had the same mac (see picture). Put numbers large enough so as not to catch the same mac of another scope, not being able to know what numbers Tektronix has arrived at, there is no other choice. --- End quote --- I know but I found the correct one in another picture. |

You can read the NVRAM but you can't write to it properly, sometimes you end up getting it into test mode where it puts out a clock signal on one of the IO pins and then it doesn't work in the scope until you get it back out. |

I bought this nvram from ebayhttps://www.ebay.com/itm/293776182478?hash=item44666cccce:g:U~gAAOSwjfBfgfa1&amdata=enc%3AAQAIAAAA4AXQYLElJ8jSjlKc%2FpN%2FWlY%2F3Ap9wEbY7cdsXbScwtxKiYJ57Ztnix5oYCxia6kNtSdBQw4DZLQz9wlvtTO9Lv9b0hKorgsi8MWxPfxCc%2BkrDgYq4f7jAoDG1d2Px1GcKEar8PbQCf42lNDW4hMZw%2Fwjls6Y6aOQpHrMLJsOnw8k8%2FRGToJ4Jhb44RmA43ALkVn0UWPQg5u3UdMUdU6vXbHFw%2B5r9YppPolmlbtOCKZLqlufOTP5dt4PEDLSsxsK9IHvsgKbNRhU%2FDIgoghIHRva2W8xt1QiJBQUvuH8K2PS%7Ctkp%3ABk9SR8rzn4iGYg I will try it in a TDS3034B, this scope only lost time, but if I remove batt, MAC address will damaged like your scope, I had that problem in a TDS3014B, I sold it to buy a MDO3024 but, again I bought two TDS3014B with batt and mac problem solved and tds3034B, also I have tds3012B, this scope hasn't problem but is probably in future happend it. |
