Huh?

Buy it or don't.

Looks ike most of the problems people have with those two oscilloscopes
are caused by their inability to use a PC.

Just to check my understanding of a "logic analyzer"... That's like when
you want to know what happens when pressing a touch swhich that goes to
some logic circuit? In other words... When a logic output goes high,
this is what happens to subsequent logic?

I'm confident that's correct, just double checking.

Thanks.


A logic analyzer can show you a record of data both before and after a
Trigger Event. You decide what data to monitor and what the Trigger
Event(s) is(are), then how much prior data and subsequent data you wish
to be able to review. This information determines the number of data
lines, speed, and storage capacity required of your LA device.

For most of us the data of interest is address and data buses along with
various interrupts, etc. based on real world interactions.


My ChronoVu LA16 enabled me to take a peek at the I2C conversation that
ensues between a motherboard and memory during the power-on self-test.
Another thread mentions the pocket sized DSO150 oscilloscope. Part
of my job entails field service, so a DSO150 was ordered for my truck's
tool kit, mostly because the price is right. It'll be interesting to see
how handy the DSO150 proves to be on service calls.

Thank you, 73,

The Hantek 6022BE obviously does lots of stuff a multimeter cannot do.
I haven't been able to log voltages for X amount of time (a simple
programmatic thing), but it does act like an oscilloscope. I can
easily and clearly see the speed control signal sent to my drone's
electronic speed controller (x4), and see that it is a pulse width
modulated signal. You just click on "Autosetup", it puts the signal in
plain view, then increase the throttle and watch what happens to the
waveform and the duty cycle readout.
