There is a 1.5/1.8 GHz model and a 3 GHz model. The unit I saw had a tracking generator and the EMC tools. I don't know if they are standard or optional. It was a really nice looking unit. We showed the 3 GHz version at Electronica. Specs should be better than comparable products in this price range. I believe the display is larger.

That's all I can say at this point. I hope to learn more at DesignCon.

Dumb question.....

Is the 50 ohms output impedance on the SDG1025 function generator always present even if I setup the Load parameter to be equal to "High-Z"?

My guess is that the answer is yes but just wanted to triple check. I assume that there is some kind of a physical 50 ohms resistor welded right before the BNC output connector so it is always there no matter what parameter you set in the function generator.

Could someone verify this for me?

Thanks.

I did wonder if you where dumb, then I thought it is a good question.

But I don't know.  :palm:
Have a scour through the links on the https://www.eevblog.com/forum/testgear/the-sdg1000-and-sdg800-thread/msg579096/#msg579096 thread.

Check the teardowns and this link:http://sigrok.org/wiki/Siglent_SDG1010
Thought this might show it but no.



You might have to do a teardown yourself for the answer.  :P

Is the 50 ohms output impedance on the SDG1025 function generator always present even if I setup the Load parameter to be equal to "High-Z"?

Simple answer. Yes. Output internal impedance is 50ohm INDEPENDENT of what value you set for LOAD impedance what setting affect only for displayed V level so that you need not yourself calculate it. Adjustment is NOT for adjust internal impedance. Adjustment tell to SDG what is your LOAD impedance. If your LOAD impedance set is right, only  then SDG display can show right Voltage level.

Inside  is "zero impedance" source -- internal impedance 50 ohm ---BNC out --- your LOAD impedance --|

>---Ri--OUT--Rload---GND

Example:
If you set HI-Z as load setting... and your SDG V level show 10V. You connect 50ohm load to output. Your level over your load is 5V.  (source voltage 10V and series 50ohm Ri and 50ohm Rload)

If you set HI-Z  as load setting... and your SDG V level show 10V You connect 1Mohm load to output. Your level over your load is around ~10V (source voltage 10V and series 50ohm Ri and 1Mohm Rload)

If you set 50ohm as load setting... and your SDG V level show 10V. You connect 50ohm load to output. Your level for your load is 10V.  (source voltage 20V and series 50ohm Ri and 50ohm Rload)

If you set 50ohm as load setting... and your SDG V level show 10V. You connect 1Mohm load to output. Your level for your load is ~20V.  (source voltage 20V and series 50ohm Ri and 50ohm Rload)

(it is also in data sheet and it is in manual)

Guys, thank you for helping me out with my question.

Before posting, I did run some experiments and I also concluded that the 50 ohms resistor was being used regardless of the Load setting chosen (50 ohms or High-Z). The problem with those tests is that they were not really conclusive (at least I think they were not conclusive).

For example, lets say that this particular function generator had two transmission lines leading up to the BNC output connector, one with a 50 ohms resistor in series and the other without the resistor. Because of this physical design, this would mean that it may be possible via some software setting (on the current or some future version of the software) to actually bypass the transmission line with the 50 ohms resistor.... Yes, i realize that my example is a dumb example but I am new to all this and right now I feel like a hormone raging teenager checking out their very first porn magazine, my mind is going all over the place!

So anyway, what I wanted to verify was that it was physically impossible to skip the 50 ohms resistor due to the hardware design. in other words, there is only one transmission line leading up to the output and such transmission line has a 50 ohms resistor welded in series on it so it is impossible to bypass the resistor via software. Based on the replies, this appears to be the case.

Thanks.

I have a warranty question. I want to buy a new SDG5082 generator. Will I still get 3year warranty coverage even though I buy from overseas or someone from eBay?
Thanks.

Yes of course you will or should.
Whether you will get any required support from your supplier is another question.

Riggght. Pull the other one, which plays Yankee Doodle.

As an aside, spot the misconnection on this Samsung TV set at my bank ( the Steve Bank) that purports to be "Made in South Africa" as well. Local TV set manufacture stopped in 1996 when the assembly plant in PE closed down, due to cheap imports. Even then they had been reduced from a full house manufacturer doing everything from design to panel and case manufacture to a kit assembler who got the local content mark from closing the back panel, placing the set in a box with a locally printed manual and placing a pair of batteries in a pack with the remote.

The audio out goes to in cieling speakers, that are powered and make a very quiet hum. Luckily they plugged the mini jack into a video component Input jack. One to the left is video out....... Sad to say the video feed is via the RF link, not via the VGA input though there is a cable attached to it, leading to a computer somewhere. Kind of a waste having a HD monitor, and feeding it a standard video signal instead of using it to it's best resolution.

Must build myself a TV be gone sometime..........

Yes.

Also as Spring Festival present SDS2000 peak detect mode started suddenly and surprisingly working.

Maybe we should advance the RTC to see what other features Siglent have decided to release that are linked to the date?  >:D

I already verified peak detect works since the most recent firmware update. Nothing new here. Peak detect still doesn't work properly in roll mode though.

Welcome to the forum.

It is.  :-+
This might indicate Siglent is starting to offer bandwidth upgrade options to some of their products.  :-+
Of course any product range incorporating the same HW theoretically should be capable of this.
Other manufacturers do it why shouldn't Siglent?

Too bad they continues to behave in such an irresponsible manner as to continue the practice of distributing software that has not been digitally signed. Such lack of consideration towards their customers security concerns.... oh well.
