| REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol |
| << < (409/566) > >> |
| Carrington:
I think it is due to the overlap of many waveforms slightly different each time, and the wave intensity processing. Like the persistence effect. Note: Test now with average acquisition mode and only 2 averages. |

If you compare this 1ns/div image with the 100MHz BW limited 1ns/div image in your previous post, the BW limit seems to have had an effect. |

BUG in latest f/w, 02.01 Delayed sweep malfunctions. To reproduce: Ch2 must be enabled, Ch1 optional acquire: 7M samples, normal trigger: ch1 or not important, Auto or Normal seems to have no effect main timebase 500us/div, delayed t.b. 100 us/div or something Then when you move the delayed t.b. towards 1 ns/div all seems well until you select 1 ns/div.. It locks up for about 10 seconds, no waveform update, no response to keys. Then it comes good and lets you go back to 2ns/div Of course this DS2072 is using the latest enable everything serial codes. |

As far as I know, Rigol has not started selling BW updates - but if/when someone on the forum has a DS2302A (or DS2302A-S), we can find out if the error(s) exist in the 'official' working version - and if so, report it to Rigol. I suggest disabling 300MHz on non-A HW v.1 models. Not only is it buggy (I've had a couple of crashes from it), but it's not really perfectly implemented in the input stage. |

How is it possible to uninstall only BW option? --- Quote from: marmad on December 30, 2013, 03:46:26 am ---I suggest disabling 300MHz on non-A HW v.1 models.
