I'm going to import this scope, and returning and/or replacing is almost impossible, I must be 101% sure about my decision. |

Well in short, all kinds of little things. It generally works well but... For timebase follows normal 1-2-5 pattern except 4ms/div instead of 5ms/div. Sometimes, when you stop acquisition and change timebase, it will loose buffer. On some triggers, sometimes stops triggering, and then you change trigger level a little and it starts again.. Not all knob presses have functions, cursors buttons are not very easy to use. There is search button that does nothing. These are very obscure things and happen only occasionally so it's not a big deal.. But perfect it's not. Still very good and portable. It already proved very useful to me and I use it very often. I plan to make a short review/summary of my findings. Just it's kinda busy now... |

The SA option was also added (only for the 2000E). Edit1: Tested successfully by some members in DS2E and MSO equipments. This will not work on 2000A because the S/N has a different format. Edit2: It seems there are more than one new combination of ClearCode(s) so test both. --- End quote --- As an updated data point, I just successfully upgraded from 50 MHz to 100 MHz on a GDS-1054B with firmware 1.28, using the javascript html and ClearCode of {0x19495CFF, 0x257130A3, 0x3D1B58BA, 0x74B0DC51}. No downgrading or safe mode required. The GDP-070B-4 probes that came with the scope are only rated for up to 70 MHz so I guess now I'll start shopping for upgraded probes :-DD |

Reporting in: 100MHz option worked on my new GDS-1054B with firmware 1.28, Clearcode line starting with 0x19495CFF is what I used as well. Did not try anything else as decode is enabled now anyway. Frankly I don't need the bandwidth this moment but thought I'd test the lis file generation and activation procedure. Thank you wgoeo and all others for you work on this. Really like this GDS-1054B and seems a bargain with the current US pricing ($310). |
