A Siglent SDG 2042X function generator.
![Scared :scared:](https://www.eevblog.com/forum/Smileys/default/scared.gif.pagespeed.ce.oZptHNcbsD.gif)
Why at all? Because I now need a function generator up to 5 MHz or so.
To date a frequency response corrected sound card to just under 90 kHz
(see below) would do mostly. But now the need to make measurements
up to around 1 MHz became necessary for:
- Verification of 20 kHz and higher low pass filters cutting out the mush above the audio band.
- Verification of two home made isolating high voltage probes for
oscilloscopes based on the design published in Everyday Practical Electronics, Jan 2016.
- Repairing a R&S UPGR 1 MHz millivoltmeter
Why Siglent SDG 2042X?
Was for a while looking at an UNI-T UTG 932. Not available in Germany. Only through Aliexpress
![Face Palm :palm:](https://www.eevblog.com/forum/Smileys/default/xfacepalm.gif.pagespeed.ic.EBDwh1hCfo.png)
, which I dislike for payment and warranty reasons. Moreover, the a bit more expensive Siglent SDG 2042X is well supported by

For me much too troublesome.
And no. My SDG 2042X will not be pimped to 100 MHz. Simply because I don't need to do so.
