A Siglent SDG 2042X function generator.
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
, which I dislike for payment and warranty reasons. Moreover, the a bit more expensive Siglent SDG 2042X is well supported by
https://www.eevblog.com/forum/testgear/program-that-can-log-from-many-multimeters/ whereas with the UTG 932 I would have to provide the required driver myself and this without a command reference for this thing
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.
