Output Characteristic The Agilent E4350B/E4351B Solar Array Simulator can be operated in three modes: fixed mode, simulator mode, and table mode. Mode switching on the Agilent SAS is accomplished over the GPIB bus via the SCPI CURRent:MODE command. You cannot switch modes from the front panel. Note: The Agilent SAS must be connected to a computer for you to be able to use the SAS functions that are available in simulator and table modes. The front panel does not indicate which mode the Agilent S

Front panel operation: You can use the front panel when the unit is operating in Simulator mode. To do this, press the Local key whenever the front panel RMT annunciator is on. Be aware however, that any voltage and current values that you enter from the front panel will have no effect on the unit while it is in Simulator mode. These front panel values will take effect as soon as the unit is placed in Fixed mode. Likewise, the OCP function only takes effect in Fixed mode. All other functions su

■ There is no restriction on the spacing between points in either voltage or current, but the points must be monotonic. Voltage values must be sent in increasing order of magnitude; current values must be sent in equal or decreasing order of magnitude. For an Agilent E4350B for example: (1,8) (50,7.8) (55,7.5) (56,7) (57, 6) (58, 4) (59,1). ■ Each table point, when combined with the table offset, cannot exceed the unit’s maximum voltage, current, or power. ■ A table cannot be deleted or redefin

Rack Mounting The Agilent SAS can be mounted in a standard l9-inch rack panel or cabinet. Rack mounting kits are available as Option 908 or 909 (with handles). Installation instructions are included with each rack mounting kit. Support rails are required when rack-mounting the Agilent SAS (see table 1-1). Temperature Performance A variable-speed fan cools the unit by drawing air through the sides and exhausting it out the back. Using Agilent rack mount or slides will not impede the flow of air.
