1-7
• 4 - Execution Error — 1 indicates execution error has occurred (parameter exceeded
allowable range) (see Appendix B, Table B-5 for details).
• 5 - Command Error — 1 indicates a command syntax error has occurred (see Appendix
B, Table B-5 for details).
• 6 - User Request — Not used (always zero).
• 7 - Power On — set once upon power-up, however ESE bit 7 set to 0 prevents Status
Byte bit 5 from being set.
1.2.7.4 OPERATION STATUS REGISTER SET
The Operation Status register set is comprised of condition, transition, event and enable regis-
ters (see Figure 1-2). Appendix B, PAR’s B.58 through B.61 provide detailed explanations of the
queries/commands for reading and modifying these registers as applicable; the transition regis-
ter cannot be modified.
The Operation condition registers record conditions which are a part of the instrument’s normal
operation. The definition of each of these bits (condition register) is as follows:
• 0 through 4 — Not used (always zero).
• 5 - Waiting for Trigger Summary — 1 indicates the unit is waiting for trigger
• 6 and 7 — Not used (always zero).
• 8 - Constant Voltage — 1 indicates the instrument is in constant voltage mode.
• 9 — Not used (always zero).
• 10 - Constant Current — 1 indicates the instrument is in constant current mode.
• 11 through 13 — Not used (always zero).
• 14 - Program Running — 1 indicates the program is running.
• 15 — Not used (always zero).
1.2.7.5 QUESTIONABLE STATUS REGISTER SET
The Questionable Status register set is comprised of condition, transition, event and enable reg-
isters (see Figure 1-2). Appendix B, PAR’s B.63 through B.66 provide detailed explanations of
the queries/commands for reading and modifying these registers as applicable; the transition
register cannot be modified.
The Questionable Condition register (see Figure 1-1) contains status bits representing data/sig-
nals which give an indication of the quality of various aspects of the signal.
