HPW Works is well-established but expensive; I personally like https://www.audiotester.de/, which has also been around for decades now and costs only 39€. --- End quote --- Download the software for the Analog Discovery. It works with a sound card for free. |

FWIW mine doesn't smell any more. For the first week I left it powered on in the spare room when not in use and that just about fixed it. Any residual is now gone. |

Quick question to the DHO1074 owners: During the brief pre-Christmas check of my new scope, I noticed that the fastest time base setting was 5 ns/div. (With firmware version 2.11.) The datasheet states 2 ns/div though. Does that only get unlocked together with the bandwidth upgrade, or is something wrong here? Actually, while I'm at it: The display of the options status is unclear to me. When it says "Limit" for the 100 MPts and 200 MHz upgrades, does that mean that I (still) have time-limited access to the option, or that the limit has been reached and the option is no longer available? In my case, neither option is usable, and that was the state right out of the box. |

2ns/div is the limit with F/V 00.02.12 (don't know if relevant) and the bandwidth upgrade to 200MHz active. My take on the "Limit" notification is that this optional feature is blocked. Otherwise I'ld expect "Trial" to be displayed with the remaining time counting down. Yet, I don't know if Rigol provides trial periods for options on these instruments. |

Do you recall, by any chance, whether you could get down to 2 ns/div before you did the bandwidth upgrade? I want to keep good Christmas etiquette and not start the hacking before I have officially received by present. ;) Being limited to 5 ns/div comes as a surprise in any case -- the datasheet certainly suggests that the 2 ns/div setting is available for all versions of the DHO1000, independent of bandwidth. Although one can make a case that it is not too relevant in a scope with 5 ns risetime. The user manual states in chapter 4.9 that the instrument comes with trial versions of the options, which get activated upon first power-on and then last for 36 hours (of operation, I assume). Hence I was wondering whether seeing all options in "Limit" status, and apparently inactive, was what is to be expected. |
