Most guys don't care about cost, it's a drop in the bucket compared to what someone purchasing one already owns in tools. You can send the psd files right through facebook messenger for a friend to review. Anybody can download the software on any computer platform, even right on your scanner if you desired. Between its ease of use, portability, after the capture interpretation, waveform library, ease of file sharing, help and support, the pico really doesn't leave much to be desired. What are you guys working on in an automotive application where a pico isn't 'fast' enough? If there was a better automotive platform then the pico, I'm sure more people would be using it. Any inductive load that is turned on and off quickly (ignition coil primary, injectors) can have a very high back EMF. If you are working with automotive signals, you need to be somewhat careful of signasl that would exceed your 'scopes rating and use an external attenuator. Many low end 'scope have no builtin attenuation or the capability to use 10X probes. Personally, I would like to see 10 or 12 bits.Īnother "interesting" spec is the maximum allowed input voltage. So a 1GS/s channel 'scope has a usable bandwidth of of about 25 Mhz (when using all 4 channels).Ī-to-D bits/sample : Again, watch that term "effective', because it means it is averaged. Despite what theory say, the usable bandwidth for capturing non-continuous signal is roughly 1/10 the sample rate. Sample rate is very important because this really determines what I call the "usable" bandwidth. Typically the sample rate is divided by the number of channels being used. This is averaging and only works on continuous signals. The number of samples per second, but be careful of the term "effective sample rate". Most of the Rigol low end 'scopes have software selectable front ends and can be hacked to much higher frequency. Bandwidth is the capability of the 'scopes analog front end to capture the wave BEFORE it is digitized. Some tips for rookies while your shopping for a DSO.īandwidth : Looks good on paper, but not that important. They are either occasionally missing, under/over sized or "extra". However, more and more often, we are looking at signals that are NOT continuous. If you are working on equipment that puts out a continuous signal, then you don't really need a digital storage 'scope. But part of that is how the 'scope is going to be used. One of the BIG problems with 'scopes these days is what I call "specs'manship".
