Overview

Overview

The Agilent 53150A/151A/152A provides two types of messages that are displayed on the Counter’s front panel and/or sent over the RS-232 serial interface. The first type is status messages, which are displayed during normal operation. The second type is error messages, which are sent via RS-232 and/or displayed when the Counter detects an error during the Self-Test procedure or during normal operation.

All messages sent over the RS-232 interface are also available via GPIB. However, these messages are not automatically sent over the GPIB interface. For information on retrieving messages over the GPIB interface, see the Agilent 53150A/151A/152A Programming Guide.
