5.2 SCPI Status Register The 9200B Series power supply records the different states of the instrument through four status registers. The four status register groups are status byte register, standard event register, query status register, and operation status register. The status byte register records the information of the other registers. - Page 42 For the Operate Event register, you send STAT:OPER? For the query. Below are the definitions: CAL (bit 0) – Calibration. This is only active when unlocking in calibration mode. This is for factory use only. On/Off (bit 1) – output state. When output turns ON, this will flag to indicate output ON upon querying.
