About this Book

Conventions Used in this Book

This book uses certain conventions to indicate elements of the Agilent 81130As user interface. The following table shows some examples:

Softkeys	Press the MODE/TRG softkey to access the Mode/
	Trigger screen.
Hardkeys	Press the MORE key to switch to the alternative
	softkey layout.
Alternate Keys	Press SHIFT + 0 (ON/OFF1) to switch on output1.
	The alternate key labelwhich is selected by
	pressing the SHIFT keyis given in parentheses.
Screen Quotes	Move the entry focus down to PULSE-PERIODand
	turn the knob to select INTERNAL PLL.
Entry Focus	The highlight field, that can be moved with the
	cursor keys, to change modes, parameters, or
	parameter formats.
:VOLTage:HIGH 3V	Full command for programming a 3 V high level.
	The upper case letters represent the short form
	of the command, which results in faster pro-
	gramming times.
*RST	Common IEEE 488 command, to reset instru-
	ment to default status.
