Think most of the mid-level AWGs from Siglent and Rigol will work with an external GPS reference, I know our SDG2042X works with 10MHz external references although we don't have a specific GPS reference. The higher end AWGs from KS and Tektronix should also work with an external GPS reference.

Best,

Thanks for the tip. I didn't know that GPS reference is so good. That can save me some money.

On another note, in Rigol's DSG800 1.5 GHz spec sheet is says, pg.2 section: "Internal Reference Frequency", that it can deliver "< 5 ppb" frequency accuracy. That's 5 parts-per-billion which I find astonishing. Its just pitty it is out of my price range.

Is < 5 ppb frequency accuracy really common in that price range of AWGs?

This is only if you buy it with Optional OCXO reference.

Reference frequency 10 MHz
Temperature stability
In temperature range 0℃ to 50℃ , reference to 25℃ < 2 ppm
Aging rate < 1 ppm/year
With option OCXO-B08 < 5 ppb
With option OCXO-B08 < 30 ppb/year

+/- 5ppb is not very good.
+/- 50mHz @10MHz 

Also did not find what is initial accuracy after factory product line calibration. Hard to believe they can promise its initial limit is <5 ppb

standard version 2ppm alone mean max +/- 140Hz error with 70MHz and then also aging.

With Rb or GPS you can get lot of better than this OCXO Option version "5ppb" class what is "only"  5x10-9 + aging etc.

Hi! Could anybody properly install the PC software for this PSG9080? I downloaded both the english and chinese version of the software from the Juntek website, but the zipped english version has CRC error. The CN version can be installed, however it could not register an .ocx controler. I added that .ocx file to the Windows and I registered it manually, so the software now can be run (an error message still show, but it can be okayed). Unfortunatelly, it does not show any text on the GUI, only the different values (frequency, amplitude, phase, etc.) can be set (if you know that what are you setting actually...).

Hi there,

@SERJSOCHI

In your first post, you asked this:

In the second post I saw that you also bought one PSG9080:

What is the best way to remove the gray bumper, as it interferes with placing the device on the shelf.

Please tell me, does this generator have a sweep sync output signal like in your picture?

Many thanks,
Florin

Unfortunately no, it doesn't have sweep sync output.
Hardware allows to implement it, so I hope manufacturer will add such option in the future firmware.

Hi all,

I'm new here. Just got a new PSG 9080 yesterday. The brand of mine is JOY-IT instead of Juntek, but it looks identical.

Been playing around a few hours and so far things look OK. I have two short questions/remarks, if I may...

1. The Apple store has an App from Juntek for controlling a PSG9080 per Bluetooth from a iOS device.  Installed and tried it but it doesn't find the generator. JOY-IT say their PSG9080 doesn't have Bluetooth. Then again, there is no mention of Bluetooth in the Juntek docs either. Has anyone ever tried this App with the original Juntek 9080?

2. Is there a way of setting the output voltage in other units than Vpp? I'd much rather use Veff or dB.

3. JOY-IT have a firmware update for 'their' PSG9080 from March 10 on their website. Unfortunately no further info or version history. Just saying...

Ralf
