When get_smurf_control is called with argument apply_dev_configs=True the function only sets the gate voltage for hemt1 and 50k1 this needs to be updated to match the structure of the new C03 cryocards so that the drain voltages and 2nd set of amplifiers are also biased properly. Currently @eehealy is seeing the current rail on Uv8 UFM at Chicago because although the gate voltages are set properly the drain voltages are railed when using this argument. The lines to update are here:
|
S.set_amplifier_bias( |
|
bias_hemt=self.exp['amp_hemt_Vg'], |
|
bias_50k=self.exp['amp_50k_Vg'] |
|
) |
