When starting a DecaDAC ramp but a trigger is not send to the DecaDAC, then the ramp is still armed.
A voltage set command also changes the ramp range. It is changed to the full output range (

QuMADA/src/qumada/instrument/custom_drivers/Harvard/Decadac.py

Line 433 in c49b60d

self.ask_raw(f"U65535;L0;D{code};")
). And the ramps slope is not set to 0.
Thus, if then a trigger is given, the DecaDAC starts to ramp to one of the bounds of its output range.
