REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
IanJ:
Hi all,
Is this a bug.....or is it just me intepreting the scope wrongly.?
DS2072 (FW v.01.00.00.03)
- Turn on both channels, probe a couple of different DC voltages.
- Whilst Ch.1 selected go to Vertical menu and select Vavg (yellow). Ch.1 Vavg is now displayed at bottom of screen in yellow.
- Select Ch.2 and go to Vertical menu and select Vavg (blue). Ch.2 is now displayed at bottom of screen in blue.......however, Ch.1 which is still yellow now reads same voltage as Ch.2.
I was looking to have Ch.1 & Ch.2 Vavg at bottom of screen. Whatever I do both the Vavg's at the bottom of the screen always read the same voltage.
PS. If use the DISPLAY ALL function under MEASURE both the V.avg's are displayed correctly in the pop-up.
Ian.

Read the first post of this thread, all the bugs are listed....
And yes it was a bug, solved in the latest FW, you can download on the first page.

See Q01_1 at page 2, and other small changes to get 200MHz of BW.

hehe, i know that schematic, i have drawn it.
Yes, they are similar, J-FET/NPN (MMBFJ309 / MMBTH10LT1) and two BC846B + AD8510.
However there is second MMBTH10LT1 in DS2000 series, as well the attenuator/compensation circuit is new.
Carrington:
Yep!
Of course, and resistors unmarked too.
Someone has a broken DS 2000 :-BROKE ? Donate it to us please, we need one LOL.
PS: By the way very good job with the schematic tinhead.
