Try getting device log (as in andyturk's link) to see main/AFE models. There are both MB and AFE limits: --- Code: ---afeid bw 1, 2 200M 3 1G 4 200M 5 350M other 200M mbid, bw 1, 5 1G-1G 2, 6 200M-500M 7 200M-1G --- End code --- --- End quote --- AFE's always report a SW ID, whereas the main board reports a HW ID... so I'm not (yet) 100% convinced the AFE's can't be software-upgraded... --- End quote --- were you able to upgrade the BW to 350 or 500 or maybe 1G? |

So... apart from the python key.py glitch (which had been mentioned before by TV84 !! |O ), i.e. line 158 'if' must be replaced by 'elif', got the same results as others... Scope is unhappy about its calibration, and SPC fails. But 1 GHz sine wave displays fine, curiously no attenuation (500mV ampl. on the siggen)... But measurements complain with a 'low resolution' warning on the rise time and frequency measurements from time to time... |

Sending the scope in to Tek in the current state will only lead to a factory reset (at best)... :-\ And as for the h/w, yes, it seems like it has the 1 GHz stuff, otherwise, I couldn't explain how it would be able to display that signal... although the fact that there's no attenuation (or some sort of compensation ??) is rather suspicious... (or maybe due to the lack of calibration ??? but still... more amplitude than the actual signal, i.e. 500 mV 1 GHz sine wave...?) |
