Teardown & Partial Review: Rigol DG1022 Arb. Function Generator

(1/2) > >>

vl400:
Bought this the other day and after seeing some of the internal pics of the DG2041A that olsenn posted opened up my DG1022 to compare. I will be testing the performance of it later so will post the results.

Here are some pics (click the thumbnail for higher res, the originals were hugh but photbucket automatically resizes them :( )...

olsenn:
Nice! I was going to by this unit, but after noticing the limits to the non-sinusoidal waveforms and arb, I decided for the more expensive model.  Let me know how it performs after you've broken it in

saturation:
The photos look like its made better.

SrS:
The 2 DACs (below the big cyclone) with their number sanded off are AD9740 & AD9744

vl400:
I will do a proper test later using a spec an or VNA but for now I thought I would post some FFT screen grabs showing that Rigol still have not fixed the level change when using the sweep function. Manual sweeping over the same 0-20MHz range shows a flat response...
