• Accessing Status Register Information on page 171
• Status Byte Group on page 177
• Status Groups on page 179

Overview

NOTE
Some of the status bits and register groups only apply to select signal generators with
certain options. For more specific information on each exception, refer to the following:
• Standard Operation Condition Register bits (see Table 4-6 on page 184)
• Baseband Operation Status Group (see page 187)
• Data Questionable Condition Register bits (see Table 4-9 on page 191)
• Data Questionable Power Condition Register bits (see Table 4-11 on page 195)
• Data Questionable Frequency Condition Register bits (see Table 4-13 on page 199)
• Data Questionable Modulation Condition Register bits (see Table 4-15 on page 203)
• Data Questionable Calibration Condition Register bit (see Table 4-16 on page 206)
• Data Questionable Bert Status Group (see page 209)
During remote operation, you may need to monitor the status of the signal generator for error
conditions or status changes. You can use the signal generator's status register system to monitor
error conditions, or condition changes, or both. In general, the error queue is easier to use than the
status registers, but the status registers provide some additional information not found in the error
queue. For more information on using the signal generator's SCPI commands to query the signal
generator's error queue, refer to the SCPI Command Reference.
The signal generator's status register system provides two major advantages:
• You can monitor the settling of the signal generator using the settling bit of the Standard
Operation Status Group's condition register.
• You can use the service request (SRQ) interrupt technique to avoid status polling, therefore giving
a speed advantage.
