Device selection as USB signal generator

Post by El Berto »

Hi to all users.
I'm here asking for advice about instrument selection.
I have an old PC with a an old sound card (dual power supply +/- 5V) used as signal generator driving an actuator driver (0 to 500Hz signal output) converting my test signal to WAV file.
I removed capacitors to get DC output.
Now my problem is following: I need to use more recent PC so I would like move to USB interface.
All USB DAC I can find have not DC output so my Idea is this: can I buy Pico oscilloscope to use it as a signal generator with DC output and 0V as reference?
Thanks.
