Hello, this weekend I've bought some equipment for my little lab, in order to make my projects easier...
Only bad thing is that maybe the machines I've gotten are a bit outdated, I think they should be ok for what I'm gonna do, basically try to repair car audio amplifiers... Anyway, I wanted to ask some questions.
1)The oscilloscope I bought is a TDS210, which is from 1997, it's digital, has start stop and memory, so I think it will be okay... Until now I had to use the dso150 with alligator clips... which was waaaaaaaaaay worse...
Even though ¿Do you think this will be enough for most audio work, or should I spend double in for example a Rigol DS1054Z?
2)Main question:
I bought an audio oscillator, and a function generator... The audio oscillator, it's named HC 0204, while the function generator is a PROMAX gf232.
The first one seems older...
The main differences are:
The audio oscillator only generates sine waves and TTL output , its output impedance is 600 ohms, and has less bandwidth (15Hz to 200kHz) but it's easier to choose one given frequency with the knob (for example 65 Hz) with +-1Hz error. It also has 40,20 and 10dB attenuators.
The other one does all types of waveforms (triangle, sine, pulse, etc), but its output impedance is 50 ohms, it's really difficult to select a chosen frequency with +-1Hz error, it only has 20dB attenuation but it has more bandwidth (0.2Hz to 2MHz).
I mainly wanted to be able to do frequency sweeps, to get the output response of the amps or any other thing... From what I saw, I can only do them by getting a 0-10V ramp signal in the VCO input of the promax GF232, so that it sweeps one full scale...
So I'm starting to think that the audio generator is not really useful for me... I don't see what it could do that the other doesn't, more than attenuating the signal, or letting me have two signals, but I can't even get the ramp signal I need to get the sweep out of the promax :/
I've seen there's a difference between the construction and workings of the internals of both equipment...
The audio oscillator uses RC network, while the generator modulates output with a sawtooth signal, anyway I couldn't appreciate much difference on the oscope with both equipment set to the same working frequency...
Could you please give me some advice?
Should I give back the audio oscillator and save money for some other thing, or is it really useful for something I'm not caring about?
Thanks a lot
