5-52 SCPI Command Reference
STATus subsystem
The STATus subsystem is used to control the status registers of the Model
2000. The commands in this subsystem are summarized in Table 5-7.
[:EVENt]? command
[:EVENt]?
:STATus:MEASurement[:EVENt]? Read Measurement Event Register
:STATus:OPERation[:EVENt]? Read Operation Event Register
:STATus:QUEStionable[:EVENt]? Read Questionable Event Register
Description These query commands are used to read the event registers. After send-
ing one of these commands and addressing the Model 2000 to talk, a dec-
imal value is sent to the computer. The binary equivalent of this value
determines which bits in the appropriate register are set. The event reg-
isters are shown in Figures 5-4, 5-5, and 5-6. Note that reading an event
register clears the bits in that register.
For example, assume that reading the Measurement Event Register re-
sults in an acquired decimal value of 544. The binary equivalent is
0000001000100000. For this binary value, bits B5 and B9 of the Measure-
ment Event Register are set.
