Hi Simone,

I'am currently sitting in the office in Trento, maybe you're not so far away ?

Pasta, oh yes, I love it  :-+

Bologna is just around the corner (at least compared to eevblog), around 200Km from Trento - which you do of course know yourself ;-)
 
But no way, I'm on the job here - though I'll keep it in mind. Both, the shop and the tortellini!  ^-^

Tomorrow morning I will be able to test the SDG6052X with a LeCroy HDO6104A 12 bit 1GHz
I should be able to test the sine wave. I’ll do my best to make a short video and print screen to share.
Please send me test request before tomorrow morning!

No, I am a software architect, not even embedded. But doesn't matter: I am in the lucky situation to do electronics just for fun. :-)

But thank you anyway, very kind offer.

Hi simone.pignatti,

Thank you for the measurements.
Does you scope has 50 Ohm input? If yes please measure as you set 50 Ohm at both generator and the scope.

High impedance termination of your cable is not very good for this kind of measurement you have done.

Also it will be nice if you can hook spectrum analyzer and show spectrum purity around single tone.

If i understand the SDG6052X specification right
we should expect -3dB drop at 500MHz with 50 Ohm termination

Or you should see only 30% level drop switching 0.5Vpp sine wave from 10MHz into 500MHz

+1.

The sine wave looks in good shape while the the amplitude is obviously not in spec. I think this is caused by the 1M input impedance setting on the scope. Reflection happens on the scope input port if it is not 50ohm impedance, and this may introduce huge amplitude distortion in high frequency.

This is totally wrong way to measure signal generator amplitude flatness and accuracy from low frequencies up to 500MHz. There is all wrong. Totally. Even if you connect external 50ohm terminator to oscilloscope input it is wrong. This oscilloscope have 50ohm internal selectable impedance but even if there is oscilloscope internal 50ohm input many times they are not at all well enough for accurate amplitude flatness measurements. Because many times they are not enough accurate 50ohm impedance over whole frequency band. Oscilloscope specs say only -3dB @ 50ohm without more detailed data. Also this cable looks like some audio quality coaxial.

About external feed thru terminator (what do not with this oscilloscope exept if want go over oscilloscope specified max level with its internal 50ohm) connected to oscilloscpe 1Mohm example 16pF input (what in real world have all three: resistance, capasitive reactance and also some inductive reactance.  Result is far away from 50ohm if look 500MHz (problems start in practice when we go roughly saying over 100MHz  and more and more out of order what higher freq we go.  If it is 50ohm terminator with coaxial T - this is most crap way. Specially if terminator is cheap "Ethernet network grade crap terminator".  Without perfect impedance match you work with standing waves what amplify your signal with some frequency anmd attenuate with some frequency, dpending these waves phase. Also these reflected return to generator output may affect its ALC depending how it is done some generators.

Fun side note about this oscilloscope. Sad that this level of scope have this kind of trigger jitter. Visible around video time position 12.15. Do they have at all fine interpolation for accurate positioning. Also there was linear interpolation. Sinc interpolation is better for sinewave like signals. 

For good level flatness measurements you need different tools. 500MHz is not anymore "audio".
Rough measurements you can do using enough good and trusted SA, also it can show  something about sinewave quality. If you claim from oscilloscope screen that sinewave quality is very very good it is bit loosy to say so.  Simply, it is difficult to see it from oscilloscope screen, exept if we talk about very poor sinewave what have very high levels of harmonics or other impurities. Example if there is second harmonic.
Think we simply combine 500MHz 0dBm  sinewave  and then 1000MHz -30dBm sinewave and this combined wave you connect to oscilloscope. What you see. Looks like quite pure 500MHz sinewave. How about if this, 500MHz sine,  1000MHz (500MHz 2. harmonic) is -20dBm and then 3. harmonic (1500MHz) is example -40dBm. Still you can see it is quite nice looking sine shape in oscilloscope screen. But in reality, it is quite poor.
 
Just for info so that random reader do not need calculate: With 500MHz,  16pF reactance is 19.9 ohms!
(16pF is because in this example it is nominal 1M input capacitance with this named oscilloscope.)



Summarized briefly:
This video do not tell anything about SDG6000 amplitude accuracy or flatness or sinewave quality.
It can be worse or better or what ever. This test is faulty for this purpose.
But, other ways still very nice to see this LeCroy model and this Siglent model live in video.
If practice and theory is not equal it tells that used application of theory  is wrong or the theory itself is wrong.
It is much easier to think an apple fall to the ground than to think that the earth and the apple will begin to move toward each other and collide.

Hi rf-loop , thanks for your comment. Yes my test setup wasn't the best and as stated I had very limited time. The idea was to show the unit working.
We are collecting better quality cables and will perform new tests in the short future to be shared.
However I was well impressed by the sine wave shape, in the past I tried other units and when generating the sine wave the results (already at half of the stated max value) wa horrible. Thanks again for helping with your experience!

Yes, it was nice to see this equipment live in video.

But, oscilloscope, even with good signal pathway from generator to scope, is wrong way to characterize  signal generator amplitude flatness over whole frequency range from LF to 500MHz.  First thing is oscilloscope itself flatness. Other thing is inaccuracy with transmission from signal gen to oscilloscope.

One good instrument for flatness measurement is wide band good power meter. Something like example Keysight U2004A  power meter or some other like this.  (with these need note that they measure total, including harmonics because they are wide band power meters. With selective level receivcers can walk over this. ) Also many spectrum analyzers are much better flatness than most of oscilloscopes.
If you have there Siglent SSA3000X you can use it. It give typically better than 1dB accuracy and now you see also more details about sine wave quality.  If you need good RF cables with good connector. Example with Huber-Suhner or Rosenberger can not go very wrong.   (there is also other goods and after then tons of total crap cables with crap connectors. Mostly these cheap crap (even if they looks like good) are useless because you can not trust anything and all tests are  just  more bad as weakest part of test setup because total error is sum of all errors and all errors can be just worst side position - or not.

10MHz is easy. 100MHz need bit more. 500MHz need really think RF. 1GHz and over, all fun magick start where 8nH inductance reactance is 50ohm and this kind of inductance is example 19mm long and 5mm thick straight copper rod. ;)

Does this pretty much have the same functionality as the SDG2000X series?

Would it be possible to do both a burst and sweep?

1.) Flat/no signal.
2.) send SDG6000X a trigger
3.) SDG sends a signal beginning at some phase and sweeps from X frequency to Y frequency.

I have probed the sine wave flatness of the SDG6052X in the whole frequency band
using SSA3021X and relatively good coax.

My results:
1MHz     +0.08dBm
100MHz  -0.03dBm
200MHz  -0.17dBm
300MHz  -0.15dBm
350MHz  -0.39dBm
400MHz  -0.11dBm
450MHz  -0.23dBm
500MHz  -0.29dBm
 
Some of the deviation is due to the generator but also some due to the cable and due to analyzer.
So the instrument seems to match its specified amplitude flatness +/-0.3dB

So far so good

Has anyone else had any experience with one of these? I have an SDG2042X, but am likely to need both higher frequency operation and faster rise/fall times.

Also, wondering if it has essentially the same command set as the SDG2000x series, since I have some ATE software that presently controls the SDG2042x and would like to avoid changing it.

Thanks,
John

I'm going to get one sometime in the next month or so but simone.pignatti should be able to give you some info as he has one.
There's a new SDG series programming guide that includes the new commands for the added features in the 6kX models. The basic command set will be the same.
Here's the new programming manual:
