Siglent SDS1104X-E vs. Rigol DS1054Z Advice?
<< < (9/86) > >>
KungFuJosh:
Cool, so the probes handle the voltage, and I don't need to worry about the input voltage in 10:1 or 100:1 as long as I'm within spec of the probes. That's what I originally thought, but I read some comments while researching the Instek as an alternative and somebody commented about that and the Rigol both only having 300V inputs, and that threw me off. Oops.  |O

I ordered a couple Pico TA131 probes. I'm not opposed to super-glueing and taping the switches to be safe.

Any recommendations on a 100:1 probe?

None in particular.
They need to be able to compensate to cover the input capacitance of the scope inputs and you would be wise to at least get scope BW or better.
You won't need to spend much as I've seen them for under $40 and you don't need the flashiest for audio work.
Just check they come with a ground spring and tip sleeves in the accessories pack.

I used a 15 MHz Tek scope for decades on audio gear - it's far higher bandwidth than you should ever need for audio.  Even the PWM frequencies of Class D amps are far below the BW limit on these older scopes.

But speaking of audio and high power amps: if you ever plan to work on a bridge mode amp and verify the output, there's three channels used up right away (input plus 2 channels in math difference mode to measure the output) plus any other signal that you're trying to track down during troubleshooting.  I never really thought about a 4 channel scope before, and now I use 2-3 channels at a time for pretty much everything.  I know not everyone goes down this path, but I'd never cut corners on a piece of test gear; sometimes that upgrade becomes very desirable once you start using the equipment and recognize its potential use.

Any opinions on these scopes?:

Cal Test CT2707
BK Precision PR100A
TPI P250R

They all spec about the same, but I dunno how they test in real life.

Thanks,
Josh

Any will be fine and they're all probably from the same maker.

Now which would I buy and why ?
The red one.

Got a couple of 100x probes in my probe bag and guess which one is easiest to find ?
When connected to a scope, guess which one is seen at a glance to identify what could be an HV connection ?

My 2c.
