Μια καλή διόπτρα για αρχάριους, αλλά αν έχετε τα χρήματα, πηγαίνετε με ένα σιγανό τηλεσκόπιο! Με αυτόν τον τρόπο δεν χρειάζεται να αναβαθμίσεις το πεδίο εφαρμογής σου όταν γίνεις πιο προηγμένος χρήστης. Απλά θυμηθείτε να αγοράσετε άλλο ένα καθετήρα, καθώς έρχεται μόνο με ένα. Προτείνω το p-150. Επίσης, μην κάνετε τον κόπο να αγοράσετε το μοντέλο των 150mhz καθώς μπορείτε να το χακάρετε στα 150mhz εύκολα, οι ανιχνευτές p-150 είναι επίσης καλοί μέχρι και πάνω από 150mhz. Θα συνιστούσα επίσης να προσθέσουμε έναν ανεμιστήρα μέσα στη μονάδα και θερμικές σωληνώσεις στα δύο τσιπ που είναι μέσα. Με αυτόν τον τρόπο θα είναι πιο συνεπές με το χρόνο, δεδομένου ότι οι υψηλότερες θερμοκρασίες δεν θα το κάνουν να μετατοπιστεί με το χρόνο.

A good beginners scope, but if you have the money go with a rigol og siglent scope! This way you dont have to upgrade your scope when you become a more advanced user. Just rember to buy another probe as it only comes with one. I recommend the pp-150. Also, dont bother with buying the 150mhz model as you can hack this to 150mhz easily, the pp-150 probes are also good up to more than 150mhz. I would also recommending adding a fan inside the unit and heatsinks to the two chips inside. This way it will be more consistent over time, since the higher temps wont cause it to drift over time. This way you can also OC it and get more out of the fft and it will act more snappier. A guy named davidAlfa made these hacks, you can find it on his YT-channel or on the eev forum. On one of his videoes he has a link to his google drive where the different hacks are listed! On the last three pictures you can see that I added a fan to the 5v rail on the psu and that I used a nut and bolt to connect the chips to the metal case for better transfer of heat with some thermal-paste. Shipping is also very fast!

Early days to give a complete appraisal, however did get familiar over these few days, and I would say it's not too bad for a budget Digital Oscilloscope and signal generator. The display is visually good clear and bright, Graticule and signal wave-forms provide the correct readings, also the read-outs are very close to the known input level; calibration also is spot-on. Can't check the maximum band-width frequency, but suspect it might not go to 100Mhz ? The built-in Generator is okay seems to give the right frequency and level output, and is useful if you are lacking this equipment, so a Two-In-One has benefits at a good price. Y Channel rotary controls can be odd on first encounter, they operate from a fast or slow rotation, can be a little irritating, but once you realise that's how they work, you just take it on-board; however you can set them for Slow rotation, but that can be even more frustrating; my thoughts are, best to leave them as you receive the Oscilloscope, in default mode. Deep Memory is enough for this Scope, was not able to see any really bad sample steps on a sine-wave, at 25Mhz; but this may be more noticeable at higher frequencies, again I can't test that high to check. Again once you become familiar with the buttons and how it operates, life working with the Scope becomes second nature, there are some short cuts you start to remember form operating it over time... my recommendation is, you play with it, to get that experience, and in the course of seeing the odd things that bugs you, they resolve into a working relationship. I would also recommend that once you have received it, you power-up the Scope only after it's been in your home for half an hour, just to get to room temperature; then go to the utility button and select Calibrate, and let it do that; if there is any issues it would resolved at that point. So far, I am happy with it... this has been a long journey to wait for Digital Oscilloscope, with good refresh rate.
