3.13.7 STATUS REPORTING
The status reporting of the EL Series Electronic Load follows the SCPI and IEEE 488.2 require-
ments.
3.13.7.1 STATUS REPORTING STRUCTURE
The status reporting of the EL uses multiple status register sets, illustrated in Figure 3-4. These
register sets are Channel Status, Channel Summary, Questionable, Operation, Standard Event
and Status Byte/Service Request registers. All registers are 16-bit registers except the Standard
Event and Status Byte/Service Request registers which are 8 bits. The Channel Status, Opera-
tion Status and Questionable registers all have condition registers which are associated with
two related registers: an event register which holds unlatched events reported in real-time by
the instrument and is cleared by reading the register, and an enable register which allows the
contents of the event register to be passed through to set the associated condition register.
3.13.7.2 STANDARD EVENT STATUS REGISTER
The Standard Event registers contains bits (condition register) is as follows:
• 0 - OPC — Operation Complete
• 1 - Not Used — always zero.
• 2 - QYE — Query Error
• 3 - DDE — Device Dependent Error
• 4 - EXE — Execution Error
• 5 - CME — Command Error
• 6 - Not Used — always zero.
• 7 - PON — Power On since this bit last read
