Well, the firmware situation seems a bit of a mess out there ... Marcell has - 00.03.00.09.00.02.11 My version is - 03.03.00.13.00.03.00 And from this official Rigol website, http://int.rigol.com/Support/SoftDownload/3 we have this for the DG1022 - 00.03.00.00.01 And yet from this official Rigol website for the DG1022 - http://beyondmeasure.rigoltech.com/acton/form/1579/001e:d-0001/0/-/-/-/-/index.htm We have this version listed as the official version - 00.02.12.00.00 I'm writing Jason right now to see what the actual real official latest version is supposed to be ... :-// |

*** Update *** After several back and forth emails to Jason @ Rigol, they have decided to send me a DG1032Z demo so I can see if the same issue arises, but they said since it was a different design, it should operate correctly as far as the external clock and frequency counting accuracy. I'll have two weeks to test it (more than enough time). Then, it seems I may have the option to "trade in" my DG1022 for such a model. They really stepped up to the plate. I'll post some pics/info when I get it. :-+ |

The DG1032Z demo unit arrived from Rigol/Jason. Will be checking it out, specifically the external clock and frequency counter as compared to the DG1022. |
| xrunner:
Well, it works the way it should, which is not the way the DG1022 did. First the frequency counter. When using an external 10 MHz ref, and measuring same, it shows the exact frequency. This is as expected, since it's a circular measurement, but the DG1022 could not do this. Second, measuring an external 10 MHz signal, when NOT using it as a reference, gives a reasonable readout of: 9.999 989 9 MHz which is off by ~ 10 Hz Very good. Next I'll see if the output drifts as compared to the ext. ref. it's locked to. |

Test #2. The generator output does not drift when using an external source. I'm using my HP 54501A project scope here set to infinite persistence. No drift noted. Ch1 - Ext. Ref. 10 MHz Ch2 - DG1032Z output 10 MHz |
