	The alternate key label—which is selected by
	pressing the SHIFT key—is 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 IEE 488 command, to reset instrument
	to default status.
