It also requires 24 volts at 2.5 amps with a proprietary dc connector, so not very portable without the optional battery back assembly.
This little handheld thing falls definitely in the toy category and in true chinese fashion was unstable until i added a 100 ohm resistor to one of the i2c data lines......
but it runs for 5 hours on a built-in battery and it is practical to use for some things except in outdoor light.
it does not have the automotive capture facility that the hs402 has, that scope tablet is nice for analyzing engine performance and i play with it with various transducers and that is satisfying, i watch a lot of automotive diagnostic video's, ATS's Bernie thompson is fascinating to watch with his e-scope tablet.
My use of scopes is very sporadic and i have no training with them but they are able to show me what i want to know so they get used from time to time
That seems to be the role of an oscilloscope: Burst need, then collect dust until the next burst need.
That said, these days (2010 and beyond) having a scope in the house seems to be the "new essential DVM" given the continuous growing complexity of current day electronics that are typically "none-serviceable".
A modern home HVAC is another example where three-phases feeds are emulated electronically to drive a blower motor efficiently. Another is evaluating a failing gas valve, and the signal commands they are receiving / statuses transmitting.
Seems to make sense to have the tool around the CB1100 if you have the time to understand technology and likely save some $$ doing so. In other words: The bar for tinkering with system electronics is higher today than in the 1960s - for sure (although I think tinkering with tube electronics is still a pain in the butt).
