Upgraded SDG1000X Plus AWG's

Hi Tautech, ;)
If you already have the Plus version of the 1000 series, can you do this test set-up?
Here I used the SDG 1032X, at 1MHz and a signal level of 999-mV and 1.1V-PP.
A short good 50-Ohm coax cable and a good 50-Ohm BNC in line terminator.
Then I show two pictures here below, one is at 999mV TT in 50-Ohm and the other is at 1.1V in 50-Ohm.
This shows the differences in the output amps.
The rise and fall times are around 3.5nSec.
I would like to see this measurement repeated on the Plus models, please.
In both measurements, I use alternating triggering so that both flanks come into view at the same time.
This is the 1MHz signal of 999mV (just before switching output)
The scope is SDS HD 12 Bit, with 500Mhz bandwidth.
First the 999mV picture almost no abberations verry good!
.
And this is ad 1.1V-PP Output Level, not bad but good be a little better.
.
So I am interested in the quality of pulse abberations.
If it is good enough from the new model I will purchase such a generator for my second workbench and then I can also use it for Bode Plost with the Siglent scope I already have there.
In any case, thank you very much!

Won't have any until next order....next year ETA.
3.5ns not possible with 1kX Plus.

Hi tautech, ;)
If the flank steepness are really 10nsec from the Plus model, then I see no reason to buy a Plus model from the 1000 series... and 446,49 Euro's!
The only reason stopping me from buying another SDG1032X, is the stupendous operation of the encoder of this series of generators, but enough has already been said about that.
Thank you for the reply!
Kind regards,
Bram

PRBS3 ~ PRBS32 code output, with adjustable rate between 10-6 bps

There are not many affordable (new) instruments on the market that can generate PRBS signals. Having built my own PRBS generator last year, I am excited to see this function now being added to this popular series of devices. But the "adjustable rate between 10-6 bps" in this quote kept me puzzled.
I now think where this comes from. According to the datasheet, the rate can be set "between 10-6 bps and 40 Mbps". That first scientific notation somehow must got degenerated into the text in the quote above ^-^ ^-^
I guess this 10-6 bps setting is included for people with a lot of patience. If I'm not mistaken, that is one bit every million seconds, so 11.6 days per bit. To play back a single, regular PRBS PN15 sequence (which has a length of 215-1 bits) would take 1040 years, not to mention that you at least need a couple of these sequences in order to do things such as locating bit errors....
