STATus Subsystem

This section describes each command and query in the STATus subsystem. The

STATus subsystem controls the parameters shown in Figure 3±7.

Figure 3±7: STATus subsystem hierarchy

Use the STATus subsystem to monitor the status of the voltages, currents, power, temperatures, fans, and the VXI Monitor.

The differences between the Event Registers and the Condition Register are as follows:

HReading the Event Register is destructive. Contents are reset to zero until an event occurs. If the triggering event disappears, the corresponding event bit remains set until the register is read or *RST (IEEE command) is performed.

HReading the Condition Register is not destructive. The Condition Register gives a real-time account of the status.

The Enable Register does not affect the related Event or Condition Registers. For example, the Enable Register for the current sense (ªSTAT:QUES:CURR:ENABLE?º) does not effect which bits are set in the Condition Register (ªSTAT:QUES:CURR:COND?º). The Enable Register does affect which bits will cause the current bit to be set in the questionable Event Register (ºSTAT:QUES?º) or the questionable condition register (ªSTAT:QUES:COND?º).

Examples:

1.Read the amperage draw used by the +5 Volt supply: STAT:QUES:CURR:LEV? P5

The system response: 17.5
