Did some testing with the new FW, and updated my Bandwidth chart.
There is not much more bandwidth on a 2072 with option 300 Mhz, the entry
of the 2072 , the non A models, dont get 300 Mhz, mine goes to 280 Mhz.
The lack of a internal 50 ohm terminator...
Also got more noise, see picture with only 1 channel, and then enable channel 2,
the difference is clear, on 1 nS the sample rate is to low for two channels.
The performance is worse on 1 nS then on 2 nS.
I did the test with the DSGH key, see option picture.
So the advantage of the new bandwidth option is not big for the non A models.
You are better off with the 200 Mhz version. So use the DSEZ key for better performance.
Edit 25/12: the key for CAN and 2202, is DSEZ, E for Can and Z for options + 200 Mhz.
Picture of the FFT i added, because i notice better function of the FFT after upgrading to version 2
The FFT function are much better to operate with the new FW.
So my DS2000, is just on the edge of 300 Mhz, on the post pictures below of EV, you an see the
litttle differences between two models, just a few dB, can also be the tolerances in the signal generators.
Normaly a tolerance off 1 dB is normal.
Marmad already stated a few posts back, the non A models where not good enough for 300 Mhz.
they had to modify the entry in the A models.
All measurements are done with the same 2072 and hardware version 1.0.1.0.0
