DSO2D10 AWG problem
Customer consultationI am a customer who purchased the DSO2D10 and recently there was an issue with the AWG.
It no longer outputs a signal and is just a set voltage of -1.8V DC.
There seems to be no reason for this as the AWG was working to drive an op amp until it stopped. Any help would be appreciated on troubleshooting this issue.

This may be that the chip LM670 has been burnt out. Please test whether there is a problem. If there is a problem, replace the same chip

Before blindly replacing parts I'd suggest you start by tracing the signals out of the DAC then through the op-amp and relay to find where things go wrong.
