My older one (GOS-658G) is out of order when I was trying to measure the level shifter voltage of the Wii Nunchuck interface shield. Besides, 658G is an analog OSC, which is not very useful when measuring transient signals or digital data. So finally, I made up my mind to get a digital OSC.
This one is 100MHz DSO, with 1GS/s sampling rate. The memory depth is 25K points. By the way, it has USB mass storage port, which is very convenient when waveform storaging is demanded.
For a Tek DSO, these features may cost me twice or more.
