Hello,
usually I mess around with low frequency and have been spoiled by having excessive resolution of waveforms. But specific task has emerged that will require 4 channels, at least 100MHz and most importantly at least 1GS/s on
all channels
at the same time.
Currently I have 25MHz PicoScopes and no real complaints about them. They do take abuse and software is feature-packed (FFT!). Initially I wanted to buy PicoScope 2408B or Rigol DS1054Z (and hack it), until I realized that instead of being cheap-o-scopes these are actually fake-o-scopes because they are only 250MS/s on 4ch and 100MHz - which is basically a sad joke, not scope.
After quite a bit of search I found that only (?) cheap-o-scope doing full 1GS/s on 4 channels is Tek TBS1104, but it hopelessly outdated otherwise (low memory etc).
Proper PicoScopes start at €2,795.00 with 6402C, but this is out of budget currently (about €1500 max).
I do like (toy-o-scope
) GW INSTEK GDS-2204E (has FFT!) but its only doing 500MS/s with all ch in use.
Currently almost out of ideas. Maybe buy two of something 2ch with trigger in-outs and sync but this will probably go out of budget.
Used stuff do not like, only maybe refurbished with new knobs. Do not like knobs that have been rubbed by someone else
Maybe TBS1104 low mem is not an issue at full tilt since there is only 10 samples per wfm anyway?
Almost forgot - there
must be option do display non-interpolated raw waveform. 10 samples per wfm is not much and when interpolated all the useful info will be lost for good.
