Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China
hpw:
HDO4000 looks for Audio nice ... BUT :palm:
- 2 years old DSO
- FW maintenance cycles a about 6 month
- Only 1M FFT
- Only Flat Top as for 16 bit this is a low performing FFT Window, as may OK for 8..12 Bits
- No dt/d math function as LeCroy & Siglent... and ??
- unknown, white background as using print screen background, as like to print later on. Or to use transparency 0% ??
- 250M to as max 500M memory
- unknown Jitter figures on reference & in case of used external 10MHz reference
Good:
- 100uV/div as lowest scale
- 16uV lowest noise may seen as lowest value on DSO entry market
the question rises, as 2 years old design, any newer DSO in pipeline?

Note that the possibility to hack a DHO1000 for the 50 Ohm input (only for ranges <=100 mV/div and with some offset issues), all software features on DHO4000 and >500 MHz BW has been proven on my 1074. Although I still couldn't find a perfect solution to the 50 Ohm input that gets me the correct gain for the 200 and 500 mV/div range .

16 microvolts RMS on a 800 MHz 1 megohm input? Not a chance, and Dave's video showed much higher noise, although not as high as I would have expected. Dave's video also showed that the ground input coupling selection does not ground the input buffer, so the noise measurement with ground coupling is useless.
Did anybody investigate the noise claim?

As far as I can remember, this was with 20 MHz bandwidth and a 50 Ohm terminator at the input. With a newer firmware the noise is about 22 uV RMS

"For audio electronics I will choose Siglent first, because of it's Bode plot capabilities. It can use two channels to analyze and generate Bode plots simultaneous on both channels on a stereo system (pic3)."
This was my only Concern, i wisch i had this on Rigol too but i have an QuantAsylum 403 Analyzer for Audio Spectrum to do great Graphs and FFT.
And for Higher Frequencies I have the little TinySA Ultra but not realy used it much till now.
I am not realy after Radiofrequencies but to watch sometimes the Wlan Channel / Frequencies used, or the Spectrum from an Switched Powersupply (EMV) is a nice Feature ;)
So the Noise and the other Stuff i mentioned before took me to "Dark" Rigol Side also the Possabillity to hack this thing easey ;)
The DS1054Z tooks also long time to get an neare bugfree Firmware so lets look wat Rigol will do in the Future with this Thing "feel the Force Rigol, it will be on youre Side"
The Hardware seems Descend on this Thing only Software seems to be abit behind on some edges.
I will find it out if i got the Scope on Friday ;)
I am an Hobbyist and need to watch my Money so 900$ was much Money for me. And dont want to go higher. \o/
The Rigol 924 and Lower Versions have to little Displays for my Eyes ;) and only 1,25 Gs on one Channel so on 4 Channels not much Left right? like on DS1054Z!
For the Pricepoint i was long time happy with this little Puppy :)
