Status register
The status register structure of the Model 6517A lets you monitor and act upon numerous
events that occur. Many programming decisions can be made by monitoring the Measure-
ment Event Register and the Operation Event Register. See the User’s Manual for details
of the status registers.
:STATus STATus
Subsystem.
:MEASurement
Path for measurement status registers:
[:EVENt]?
Use to read the Measurement Event Register.
:OPERation
Path for operation status registers:
[:EVENt]?
Use to read the Operation Event Register.
When an event register is read, a decimal value is sent to the computer. The binary equiva-
lent determines which bits in the register are set. For example, a decimal value of 33 indi-
cates that bits B0 and B5 are set. An event register is cleared when it is read. Sending
*CLS
clears all event registers.
Some of the more useful bits of these event registers are summarized as follows:
Measurement Event Register Operation Event Register
Bit B0 set = Reading Overflow Bit B9 set = Calculating
Bit B5 set = Reading Available Bit B10 set = Idle
Bit B7 set = Buffer Available Bit B11 set = Sequence Test Running
Bit B8 set = Buffer Half Full
Bit B9 set = Buffer Full
Bit B14 set = V-Source Compliance
