Hi folks. My first post - total newb, so please consider being kind, as I have already read other material on this website, so my apologies if I missed some basic info already posted for this model on
https://www.eevblog.com/forum/testgear/rigol-dho800900-topic-collection/msg5144856/#msg5144856 or elsewhere.
I recently purchased a Rigol DHO914S with the intent to learn about audio work and soundwaves, and develop some building and repair skills. I am an active musician, but I do not have good electrical or technical skills (yet!). My basic purpose is to become very familiar with a solid good long-term basic machine so I can observe soundwaves from my various instruments (guitar, synth, percussion, etc), do any necessary testing and troubleshooting for noise/errors/overtones/tuning, and also perhaps in the future do some basic building and repair of sound effects devices (e.g., guitar pedals, guitar tech work) plus maybe some more complex synth, stereo, speaker repair and building. Primarily analog work, but perhaps if I become more adept then digital as well. Gotta walk before I can run. And actually I am in crawl mode . . .
So, in terms of first steps one of the initial things I want to do is simply connect devices correctly just to observe signals and start learning the machine. I know there are some probes in the Rigol box, but what I really want to do is connect 1/4" and 1/8" mono audio outputs into the Rigol BNC inputs. I am seeing a bunch of BNC adapters online, but am already getting confused about specs, and I don't want to waste money on a crappy adapter because it will be so core to the system. So, could anyone please just kindly take a moment to recommend the best BNC adapter for mono audio inputs? I presume I want one with male BNC, correct (the output on the Rigol hardware is female, right?). And, I am hoping for a TS female cable - ideally really high quality with the correct impedance or other features for this particular Rigol machine (I am not clear on which electrical specs to match/consider when I look at the manual?). I don't mind paying up for four good adapters that are solid, nor using a reputable dealer rather than some random amazon shot-in-the-dark. All suggestions for parts or dealers are welcome. I just know I want it in a high-quality low-noise durable cable (so there is flexibility and a bit of length such as 6 to 12 inches or so) rather than in a short stubby inflexible all-metal adapter.
Beyond that, are there perhaps other types of connectors I should consider? RCA will likely be next on the list, seems easy enough. Any others? I see some "kits" out there, but not sure if many of the parts are irrelevant for audio testing and building, versus non-audio use where I just will not be interested.
Next, if I am just doing audio is there any need for me to hack the 914S up to 924S for bandwidth? I see some posts on hacking, but I don't think this is needed for my use case, and I already paid up for the 914S to get AWG and avoid any odd issues. No need for me to sweat doubling the bandwidth, correct?
Finally, is there perhaps a topic thread already about using the AWG in this particular model? Apologies again if I missed this. While I have plenty of synths to generate sound, I wanted the clean AWG signal, and I wanted it integrated with the scope, so I will be watching some videos to learn about the AWG features, and some good tricks - but I am happy for any recommendations on content, or links to specific AWG info for this particular model.
I hope those are fair questions, and perhaps if I have missed a thread on these particular topics someone can kindly just cross-reference it, and be patient with my very rudimentary inquiries here.
