Fixed several bugs
a) [2017/04/07-92573] Digit changes when setting delay of Pulse by the knob
I can confirm slow rotary encoder on Siglent SDG2042X with latest FW 2.01.01.35R3B2. I would prefer for it to respond faster, it is pretty slow. Rotary encoder misses some faster steps, but do not change direction or do something random. It is not a bug IMHO![]()
SDG2000X FW revision 2.01.01.35R3B1 has a note on rotary encoder:QuoteFixed several bugs
a) [2017/04/07-92573] Digit changes when setting delay of Pulse by the knobt seems there were some problems with rotary encoder and button debouncing (Dave noted that on SDG2000X review video, EEVblog #806 - Siglent SDG2000X, 17:20) so Siglent made very conservative button debouncing algorithm. As a side effect, this slows down rotary encoder response rate.
I have a Siglent SDG2042X and I'm really disappointed in the rotary encoder's performance.
Unless I turn it really slowly, it either skips steps or even counts backwards.

2/16/2020 1.01.01.33R1B6 1. Optimized debounce of the front panel buttons
I also bought mine a few days ago. I repeated what you did in your video and my generator doesn't act that way. The only similarity is that it counts encoder pulses up to a certain speed. It should be more responsive. But it rarely goes back one digit. I have to turn the knob very quickly. Mine is also updated to 1062X from the tutorial on this forum and does not have the latest firmware. Perhaps that also matters or simply the encoder is broken.. I did the update practically right after the purchase.
Wonder where the Siglent reps are...?
SDG6000X shows the same crappy encoder behaviour.

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.

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?

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?
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
