No need of such, that's what Backup builder does, make your backup before doing anything, then whatever happens, restore it.
Hi David, sorry to cause problems here!
One of the issues here is that there is little/no information inside the packages that shows what each UPK actually changes. For example, the readme for "dso3kb_2D15_conversion.upk" doesn't state what files get changed and how to revert back afterwards. So I was unsure that BackupBuilder could restore that factory Model Number data.
Anyway, I installed the 2C15 upgrade on my
2C10 and here is info from
factory AWG calibration:
Process: Upgraded 2C10 to 2C15, then Restore Defaults, then Utility > Calibrate (the DSO). Probe at 1x.
AWG: Sine 1kHz @
600mV100mV/Div gives AY 296, BY -296 = 592mV (offset zero)
50mV/Div gives AY 294, BY -296 = 590mV (real offset -1.0mV)
20mV/Div gives AY 289.6, BY -296 = 585.6V (real offset -3.2mV)
10mV/Div gives AY 283.2, BY -290.8 = 574mV (real offset -3.8mV)
AWG: Sine 1kHz @
1000mV200mV/Div gives AY 504, BY -496 = 1000mV (real offset +4.0mV)
100mV/Div gives AY 496, BY -496 = 992mV (zero offset)
50mV/Div gives AY 488, BY -494 = 982mV (real offset -3mV)
20mV/Div gives AY 480.8, BY -492.8 = 973.6V (real offset -6.0mV)
10mV/Div gives AY 472.8, BY -483.6 = 956.4mV (real offset -5.4mV)
Note 1. At low mV/div I measured AY and BY separately after scrolling V Position. In each case I cursored to the outside surface of the noise envelope.
Note 2. My "Real Offset" is the offset from Zero Volts ie: (-AY - BY)/2
WHAT CAN WE LEARN from my test?1. The factory offset calibration must be for 100mV/DIV
2. When display mV/Div is reduced, the Measured Amplitude reduces, and offset shifts to negative.
3. The DSO measurements cannot be trusted, so it's pointless to use it to calibrate it's own AWG
Cheers, John
