Expectations with RP
Posted: Thu Jan 21, 2016 8:37 pm
So far after having some setting up problems with my RP (Thanks support! very well done) I’m starting to use my RPitaya and my comments are the following:
As electronic engineer with extensive experience in the electronic workbench I confess that my expectations with RP are not the same when I order this board.
1) With the RedPitaya I don’t have the same confidence and reliability that I have with my old oscilloscope. I don’t know if what I am measuring is noise or false signal or it is the real one. I don’t have handy some signal of reference. When I was using the generator with a square signal to use as reference, the only value of Vcc = 4.6V, only shows a noise with uncertainty values, but with a simple tester I could read a value or ripple and VCC.
2) With a Red Pitaya I don’t have the emulation of rotary dial as the normal oscilloscope, and for this purpose in RP to change the range take for ever to enter a new value. So far is a nice gadget but no practical. Example: If I want to see only the values of the ripple in some power supply, I found this task not easy to measure.
3) Per example I can’t see with RP low signal that trigger SCR or Triacs. Doesn’t have the controls to make versatile this measurement.
The user never knows when the real signal is present!
4) With RP the zoom or manipulation of the image are amazingly good, when you are certainly known the correct wave is present.
5) Offers the option to play with acquisition of signals but although still I don’t find any place with tutorials that teach how to do things from the start level.
6) RP advertise, that this tool is for beginners to engineers. Take as reference of Arduino in the level of tutorials that exist in the Arduino.org website. Hopefully the RP in the future will be with such support and examples ready to use. But please don’t claim that this tool easy to use. I don't purchase because was easy to use but is as good as a analog or digital oscilloscope.
So far I think this device is not complete. Only the process to update to a new version is terribly complicated. Should be automatic or manual but selectable and with a run button. Although it has so much potential to interact with other tools as Matlab or some simulator as Proteus. The price that they charge is high for what is put in the bench.
If you think otherwise, please point me in the right directions and attach some examples/links that could help everybody in this
