Status Byte Query<br />
Syntax: *STB?<br />
Parameters: None<br />
Function:<br />
This query returns the contents of the Status Byte which records current<br />
system conditions. Appendix C describes the Status Byte in detail.<br />
If a bit is set in the Status Byte Register and it’s corresponding bit is set in the<br />
Service Request Enable Register, then a service request will be generated<br />
once for the given event. When service is being requested, bit 6 is set in the<br />
byte returned by a serial poll of the 2832-C.<br />
The Status Byte Register is an 8-bit, bit mapped register, with each bit signifying<br />
a different condition. When a bit is set, or has a value of one, then the<br />
condition is true. The bits are listed below, most significant bit first:<br />

Self Test Query<br />
Syntax: *TST?<br />
Parameters: None<br />
Function:<br />
As defined in the IEEE 488.2 standard, the *TST? command causes the device<br />
to return a result of a self-test, indicating whether or not the unit completed<br />
the self-test without any errors. The self test is only administered upon reset<br />
or power up. The query does not initiate the self test and only returns a 0<br />
indicating that the system passed its earlier self test.<br />
Returns: 0<br />
