Now there are lower values for DC offset. I've set 1mV/div, 1ms/div, using 1Mpts/10Mpts deep memory. From 10Mpts up there are no difference in measurements and FFT plots. The noise levels for measurements without filters are identical. For 02.04, the FFT level at 20 Mhz BW is about 12dB lower than the level for full BW. For 02.12, the difference is about 8dB. It seems that the filter for 20 Mhz has been changed. I'll be back with some interesting captures regarding HiRes. --- End quote --- Hello, How to get firmware 00.02.04 from DHO1074?

I have this behaviour too on the Timebase encoder. |

Best regards egonotto --- End quote --- Old firmware versions are still available here : https://rigolshop.eu/dho1074.html Go down and click on Software & Firmware tab. You just copy the firmware on USB stick and update using the Menu / Storage / Upgrade, no matter the version. You can install and older version over a newer one. |

Hello Has anyone tested the 10mhz clock reference clock input in HD100x and does this port actually work as it should? There were some problems with old rigol models reference input - https://www.eevblog.com/forum/testgear/help-with-rigol-ds4014e-on-10mhz-external-ref/ Regards |
