Siglent SDG810 vs. SDG1010
« on: January 27, 2015, 11:01:56 pm »
Wondering what practical difference there is between these two function generators. Their key specs seem to be identical, front panel is identical aside from coloring, etc. But the SDG810 is $50 cheaper. Is there any difference I'm missing?

You'll need to study the datasheets to spot them all.
800 series have only 1 output channel.
Risetime is not as fast.
P-P output not as high
etc, etc

Most of the info you seek will be linked from this thread:

P-P output not as high

I think this is mistake.
In some data sheet there is missing output levels when load is Hi-Z.
Maximum levels are same as in SDG1000 series main channel CH1.

Up to 10MHz
Hi-Z load 20Vpp (max +10V and -10V including offset)
50 ohm load 10Vpp  (max +5V and -5V including offset)

Sidenote: Using  Arb function there can produce example Square, Pulse, or Sinewave.
If there do example over 10MHz Square, pulse, sine (or what ever) it do not automatically limit output level settings because Arb max setting is 5MHz. But this, of course,  do not mean that Arb output limited to 5MHz, not even in SDG805. Just have tested 20MHz Arb sine and  Arb square out from SDG805.
EV of course. Cars with smoke exhaust pipes - go to museum. In Finland quite all electric power is made using nuclear, wind, solar and water.

Confirmed.
I did not have an 800 series to test and got the imformation from the datasheet V1.1 and yes it lists only for 50 Ohm 10Vpp.

Yes, they need correct this data sheet! order to avoid confusion.  Also I know it sure only after my own check with SDG800 in my hand. (and overall, Siglent  also need develop data sheets better and more complete and perfect for all products. HP and Tek old and new data sheets are good study material how these need do)
It looks like there is also other and more serious mistake in data sheet. (but this later after double check that I have not done any mistake)  This level mistake do not tell wrong information,  but this other (not yet fully confirmed) give really wrong information what is always more severe (= "missing data is always better than wrong data")

Edit ADD:

In SDG800 data sheet read Pulse mode minimum pulse width is 16ns
I have tested ONLY with SDG805.  In this model minimum Pulse width is 48ns.
