7 128 Power On 1 = Test Set’s power supply has been turned off and then on since the
last time this register was read.
6 64 User
Request
Not implemented in Test Set.
5 32 Command
Error
1 = The Test Set detected an error while trying to process a command.
The following events cause a command error:
An IEEE 488.2 syntax error. This means that the Test Set received a
message that did not follow the syntax defined by the Standard.
A semantic error. For example, the Test Set received an incorrectly
spelled command.
The Test Set received a Group Execute Trigger (GET) inside a program
message.
4 16 Execution
Error
1 = The Test Set detected an error while trying to execute a command.
The following events cause an execution error:
A <PROGRAM DATA> element received in a command is outside the
legal range for the Test Set or is inconsistent with the operation of the
Test Set.
The Test Set could not execute a valid command due to some Test Set
hardware/firmware condition.
3 8 Device
Dependent
Error
1 = A Test Set dependent error has occurred. This means that some Test
Set operation did not execute properly due to some internal condition,
such as overrange. This bit indicates that the error was not a command,
query, or execution error.
