Figure 4-16
Status byte register
*TRG — Trigger
Description
Use the *TRG command to issue a GPIB trigger to the Model 2010. It has the same effect as
a group execute trigger (GET).
Use the *TRG command as an event to control operation. The Model 2010 reacts to this
trigger if BUS is the programmed control source. The control source is programmed from the
TRIGger subsystem (see Section 5).

*TST?-Self-Test Query

Description
Use this query command to perform a checksum test on ROM. The command places the
coded result (0 or 1) in the Output Queue. When the Model 2010 is addressed to talk, the coded
result is sent from the Output Queue to the computer.
A returned value of zero (0) indicates that the test passed, and a value of one (1) indicates that
the test failed.
