That flicker is a known issue with one of the firmware revisions. Solutions exists on eevblog. I have 2 rigols 50Mhz (ds1052e) & 100Mhz (ds1102e), and a TEK TDS-320. After i got the rigols , i hardly ever turn on the TEK. (Earprotection required when the TEK is on , and i just turn it on if i doubt the rigols , witch has been wrong until now). I like the rigols , and after it became "publicly known" that the 50Mhz and the 100Mhz was same hardware. Rigol dropped the price on the ds1102e , to around +50$ , compared to the ds1052e. The ds1052e was limited to 50Mhz by it's model number in the firmware , but 2 simple commands via USB or RS-232. Would change the model & serial number , and on next boot you had a 1102e. Rigol has tried to prevent that in newer firmwares , but the guys at eevblog keeps modding firmwares , so you're allowed to downgrade to the version that can change the model & SN. That said , today i'd prob. pay the +50$ for an "original" 100Mhz. On the "More expensive scopes" , i have seen several. Choosing Hameg scopes instead of HP , due to function & prices. http://jeelabs.org/2011/12/21/getting-an-oscilloscope-part-2/ http://jeelabs.org/2011/12/22/my-scope-story-conclusion/ http://jeelabs.org/2012/04/06/hameg-scope-update/ CFO - Tnut Beginner Denmark _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
