I'm thinking about getting a scope and signal generator to help with my learning and troubleshooting. I've been reading a bunch of threads here and on other forums, hitting up youtube etc. I'm thinking about getting a Siglent 1202x-e. I wouldn't be opposed to getting something with more channels but everything i'm seeing tells me that this scope will do more than i'll need. The next model up (1104x-e) can be software unlocked to be essentially a 4 channel version of the 1202x-e but that appears to be pretty big overkill for this work. I thought about picking up a used Tek, but my desk space is at a premium and i don't want to roll the dice on equipment i'm not familiar with already. I'd like to get a set of high voltage probes (100:1 is what i think i need) to be able to examine the b+ power supply in my amps. I'm don't have a ton of experience here so i'm wondering if anyone could suggest a good set of probes for this use? I'm also looking at this signal generator which seems like it will work well for what we do here. I understand i can use my phone, or an ipad or whatever for this, i'd like to get a separate device so i can keep my phone separate. I think i'll need to get an appropriate BNC cable for this and then wire up a simple 1/4" jack to connect to to interface with my amp - and i can use mini-grabbers to attach the signal generation to different gain stages in the amp directly as needed. Does this sound like a good setup for working on tube amps? I understand it's probably a bit more than is necessary in a lot of ways but also seems to be a relatively modest digital setup.
