Keysight E8402A, E8404A C-Size Mainframes User and Service Guide 151STATus Subsystem Programming the Enhanced MonitorSTATus:QUEStionable:VOLTage:ENABle <mask>STATus:QUEStionable:VOLTage:ENABle?The STATus:QUEStionable:VOLTage:ENABle command sets the value of theenable register for the VOLTage status group.The STATus:QUEStionable:VOLTage:ENABle query returns an integer representingthe value of the enable register for the VOLTage status group.The enable register specifies which bits in the event register can generate asummary bit. The instrument logically ANDs corresponding bits in the event andenable registers, and ORs all the resulting bits to obtain a summary bit. Summarybits are, in turn, recorded in another register. The questionable voltage statussummary bit is recorded in the Questionable Condition Register. Enable registersare read-write. Enable registers are not affected by *CLS (Clear status). Queryingenable registers does not affect them.ParametersReturned DataComments– Refer to STATus:QUEStionable:VOLTage:CONDition? for a description ofeach bit in the VOLTage status group.– If *PSC was set to 0 prior to power-down, then at power-on, the enableregisters are loaded from non-volatile memory. Therefore, any values thatyou have stored (SYSTem:NVSave command) are returned to the registers.However, if *PSC was set to 1, then at power-on the factory defaults arereturned. The value 487 includes all power supples except P5STby andP5EXt.Name Type Range Default Description<mask> int16 0 - 32767 487(see 2ndcomment below)Bit mask for the enable register of theVOLTage status group.Type Range Descriptionint16 0 - 32767 Mask value.
