Power Module Turn-On State

When you turn on the mainframe, the power module goes through a self-test. All front panel readout digits and annunciators turn on briefly. The panel then remains in the state shown in Table 3-1A.

Note

The figure assumes the power module still retains its factory default turn-on state. You can change this

 

state if desired (see "Chapter 4 - Basic Power Module Commands").

 

 

Checking Basic Module Functions

The power module is designed for remote programming over the GPIB. It also can be locally programmed from the optional Agilent 66001A MPS Keyboard. Table 3-2 gives the SCPI commands for the remotely programmed tests. You can send these same commands from the keyboard (see "Appendix B").
