Operating the Power System 4

System-Related Operations

Self-Test

A power-onself-test occurs automatically when you turn on the power system. This test assures you that the instrument is operational. If the self-test is successful, the power system will continue to operate normally. If the self-test fails, the front panel Err indicator comes on. Press the Error key to display the list of errors on the front panel. Refer to the Service Guide for further information.

Cycle AC power.	*TST?

Instrument Identification

For Agilent N6700 mainframes, you can return the model number, serial number, firmware revision, backup and active firmware. For power modules, you can return the model number, serial number, installed options, voltage, current and power rating.

Front Panel:	SCPI Command:

Instrument State Storage

The power system has two storage locations in non-volatile memory to store instrument states. The locations are numbered 0 and 1. Any state previously stored in the same location will be overwritten.

	Front Panel:	SCPI Command:
	Select States\SaveRecall.	To save a state:
	In the SaveRecall field, enter a	*SAV <n>
	In the SaveRecall field, enter a	To recall a state:
	location from 0 to 1, and press	To recall a state:
	location from 0 to 1, and press	*RCL <n>
	Select. Select Save to save the	*RCL <n>
	Select. Select Save to save the
	state or Recall to recall a state.

When shipped from the factory, the power system is configured to automatically recall the reset (*RST) settings at power-on. However, you can configure the power system to use the settings stored in memory location 0 at power-on.

Front Panel:	SCPI Command:
Select States\PowerOn.	OUTP:PON:STAT RCL0
Select Recall State 0, then press
