Status Reporting System
General Status Register Model
General Status Register Model
The Agilent E5052A has a status reporting system to report the condition of the instrument.
Figure B-1
General status register model
The status reporting system has a hierarchical structure as shown in Figure B-1. When the
instrument satisfies a particular condition, the corresponding bit of the event register is set
to 1. Therefore, you can check the instrument status by reading the event register.
When the event register bit is set to “1” and the corresponding enable register bit (the bit
marked with an arrow in Figure B-1) is also “1,” the summary bit of the status byte register
is set to “1.” You can read the status byte register by using the serial poll.
If the bit of the service request enable register is “1,” a service request (SRQ) is generated
by the positive transition of the corresponding status byte register bit. By generating SRQ,
you can notify the controller that the E5052A is requesting service. In other words,
interruption by SRQ can be programmed.
For more information on using SRQ, see “Using the Status Register” on page 55 and
“Using the status reporting system” on page 86.
NOTE
A different status-reporting system is used for each parser, such as GPIB, VBA, Telnet, or
SICL-LAN. For example, if you mask the status register with VBA, the masking is valid
only when VBA is used.
