I have the scope i my hand a few hours, as first impression i would say : very good.
luckily no high pitch noise from internal PSU ... but hummy FAN, i guess some far east cheapo model, it will not last long there
It came with FW 1.06, i flashed it with FW 1.20 taken from GW web site, the first thing i noticed is the UI responsivity, almost real time, under this aspect it's way better than my Rigol DS1074Z, also the screen
panel waveform update looks smoother, especially with 1ms or slower time base and last but not the least, the autoset function is lighting fast and effective.
The lcd screen panel image put to shame the DS1074Z : very sharp pixel, good color tone, good vision angle, backlight intensity control (thank you very much GW),
high readibility text fonts.
I can read most important settings (measures, time base, acquisition rate, acquisition number of point etc etc) at first glance with no more eyes sore, so my goal was achieved !
Yes, i can confirm Dave's impression, some scratchy control knobs (the smaller ones) but i can leave with it, i guess will get better after some break in.
The front panel style is sure not latest fashion but apart some odd text/backgroung coupling i consider it "fair".
UI wise i would change a couple of mechanisms but it's a lot better than expected, the only real gripe is the absence of fine vertical amplitude scale adjustment.
It's my first GW Instek product, for the price seems good.
