--- Quote ---tautech 3 weeks ago This ^ yet Joe does have a quite reasonable expectation for the encoder to perform better than it does however one doesn't normally use the encoder for large adjustments when keypad use is faster and more precise. Despite this, the issue of encoder performance is in front of high ranking personnel at Siglent for them to review and review they should as their products are making headway onto the benches of experienced engineers many of which have only previously used A brand equipment. Poor performance will only have them resist obtaining further Siglent products. Nevertheless here in NZ SDG1032X remains our most popular AWG. --- End quote --- Makes you wonder why they include an encoder if their customers use the keypad. Personally I am a fan of having the encoder for reasons I previously mentioned. As I mentioned, I am thinking to get one for my own private use. Does the encoder work any better on Siglent's higher end units? https://siglentna.com/waveform-generators/sdg2000x-series-functionarbitrary-waveform-generators/ |

Nearly a decade back SDG1000 (before 1kX) their encoders and/or keypads did play up until a firmware update was released that specifically targeted debounce issues which fixed those units until szszoke and you raise this issue again. FYI Siglent arbs have always sported both keypads and encoders and we each have a preferred way of using them which for me is small increments usually always with the encoder and large ones with the keypad as I often find my time precious so need to use any instrument in the most efficient way. YYMV. I can't comment on encoders in SDG7000A arbs until one crosses my desk however at the price they are that might be quite a while. Has your SDG1032X encoder settled with some use ? |

--- Quote from: szszoke on May 08, 2021, 09:14:06 am ---I have a Siglent SDG2042X and I'm really disappointed in the rotary encoder's performance. If I do the same on the SGD2042, the unit registers 1 or maybe 2 steps but very often it counts 1-2 steps in the wrong direction. Can someone try their own unit and tell me if the rotary knob behaves the same way? --- End quote --- The point is that is a mechanical piece and has it's MTBF. So cheap as it gets to survive the warranty period. :palm: The question will be: - how to replace or damage the sandwiched gear, or requires a full/complete front to replace - where and which part to order, length, solder figures to PCB, steps incremental, knob to fit over my LeCroy WM8000A (2003 manufactured) did the same on horizontal stepping, RS-Component as original as about 3$/piece and gear at may at xx..xxxk US as new :-DD |

So far, I have not had any problems with encoders outside of some that had been damaged during shipping (broken shafts). The Siglent was new in the box from the factory and it seems a common problem with the brand. I can't imagine having a scope of other equipment from them with problematic encoders. |

Siglent released new firmware 2.01.01.37R3 for SDG2000X, it is discussed on the forum. FW upgrade seems to improve rotary encoder operation IMO. |
