Front Panel Operation
Introduction
Note Only in Fixed mode are front panel operations fully functional. The Agilent SAS can be operated as a
standard dc source in Fixed mode. SAS functions are available when the unit is set to Simulator or Table
mode. You cannot switch modes from the front panel. Modes can only be switched over the GPIB.
This chapter shows you how to operate the unit from front panel. It is assumed that you are familiar with the turn-on
checkout procedure in chapter 3. That chapter describes how to perform basic functions from the control panel. Operations
that you can perform are:
Enabling or disabling the Agilent SAS output. Saving operating states in nonvolatile memory.
Setting the output voltage and current. Recalling operating states from nonvolatile memory.
Monitoring the output voltage and current. Setting the Agilent SAS GPIB bus address.
Setting the overvoltage protection trip point. Displaying error codes created during remote operation.
Enabling the overcurrent protection circuit (OCP). Enabling local (front panel) operation.
Clearing protection functions. Calibration (see appendix B).
Key Functions
The front panel is summarized in Figure 5-1 and Table 5-1. Some keys have two functions. For example, the System
key can be used either to recall a stored operating state or to (store) an operating state. The first operation is shown
on the key and the second (shifted) operation is shown in blue above the key. In order to do a shifted operation, first press
the solid blue key, which is unlabeled but shown throughout this manual as
.
For example, for a recall operation, press the recall key
. For a save operation, press the Save key, which is
. When you do this, the Shift annunciator will light to remind you that the
key is now functioning as
the
key. In this chapter, such a shifted operation may be shown simply as .
