REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol

<< < (162/566) > >>

Wim13:
 :scared: Got my trail options back 2156 minutes, with new update installed.  :scared:

The procedure is still the same.

So you keep your trail options when upgrading, you dont lose it after the first Self-cal.
but you wil lose it on the second  self-cal and every self-cal after

( Note; some users reports other experiences about the first self-cal, maybe it is unit and configration depended. )

Small difference is that if the options are expired, you dont get this
message anymore at startup. When expired you cant find that anymore somewhere.

Good to know. Thanks for testing and sharing your findings  ;)

Hello
my DS2072 saved screens on the flash as .trc files. Searching all inet I have no idea how to work with it.
Does anybody know what it is? Example in attachment.
Thanks in advance,
Vladimir

From DS2000 User Manual:

"1. Traces
Save the waveform data in external memory in “*.trc” format. The data of all the channels turned on can be saved in the same file. At recall, the data will be displayed on the screen directly."

TRC is just an image of the waveforms on the screen - kind of like an image file (e.g. BMP) but one that can be loaded back onto the display of the DSO.

then your options are long ago expired..., so it is a real solution..., good thinking from Rigol.

1) This is not a solution - it's a bug that hasn't been fixed. Self-calibration should not affect trial minutes not matter how many you do.

2) As mentioned before, I installed a brand new trial license key - did one self calibration - and the trial minutes were erased. So this does not work in every situation.

3) Until more is known about the parameters, self-calibration is still not something I would recommend new users do - unless they have a spare trial license key or until their trial minutes are gone.
