Hi Rudi -- thanks for the very nice video! A couple of additional points about Bode plots on the RTB: 1) Horizontal scaling of the gain and phase is possible: you can use the horizontal rotary knobs, start and stop frequency, or "pinch" gestures to scale the results horizontally. 2) You can also use the Autoset key to scale the Bode plot automatically 3) HiRes mode is switched on during Bode plot measurements, and this provides up to 16-bit resolution Again, many thanks! Looking forward to the next video.
Thanks, Paul, thanks for the compliments. Just did one more test prompted by your message and I indeed do now see how the horizontal scale can be edited after the measurements are done (your point 1) - will add it to the overview table. The topic of resolution/dynamic range for Bode plots is a complex one. For each new measurement, the instrument may reconsider the appropriate channel gain for the measurement, so it is not only dependent on the resolution of the ADC or other related measures (like averaging) but also the ability to jump to the right channel gain, and the highest available channel gain (and its noise floor). So the dynamic range may be more than 8, 10 or even 16 bit would allow for, but how much, depends on other factors. Topic of next video is not yet decided but it might well be ... FFT
Thank you for your video, I've got a question about the SDS2000x Plus, I've searched the manual but I can't find much info about the selection options for the input channels. Can you put a math function as an input to the bode analyzer. For example if I had one channel measuring voltage and another measuring current could I plot V/I vs frequency with the bode analyzer. Have you ever experimented with this? Thanks
Hi! In my comparison documents, in the table on Bode plots (page 37), I wrote that "Selectable channels for DUT in and out (Analog)" are the four analog channels. Since I happened to be doing a measurement with the SDS this morning, I took another look at that and can confirm that. It's A1 to A4 only. So, math channels as an input for bode plots does not seem possible. Hope this helps!
No problem. Its the Behringer XENYX QX1002USB. (www.behringer.com/product.html?modelCode=P0ALP). Use it as a Swiss pocket knife here, after my trusty Mackie 1202 (which I had in several versions since the 1990s) was got 'dislocated' at a gig or so.

Nice compare, thank you for running it!
Thanks, my pleasure!

uhm if you dont mind me asking... but also what was the model name for the behringer mixer dut ?
