			Programming Reference
			SCPI Instrument Command List
Description	Use this command to set and read the data format of channels 1 and 2
	when using PATTERN mode. If you dont specify a channel number in the
	command, channel 1 is assumed.
	RZ	Return to Zero. An RZ pulse is generated for each 1 in
		the data. You can vary the width, edges and levels of the
		pulse.
	R1	Return to One. An R1 pulse is generated for each 0 in
		the data. You can vary the width, edges and levels of the
		pulse.
	NRZ	Non Return to Zero. A pulse of 100% dutycycle is
		generated for each 1 in the data. You can vary the
		edges and levels of the pulse.
Example	:DIG:SIGN:FORM NRZ		Set channel 1 data format to NRZ

Command	:DISP
Long	:DISPlay[:WINDow][:STATe]
Form	Set & Query
Parameter	ON OFF 1 0
*RST value	ON
Description	This command is used to turn the frontpanel display on and off.
	Switching off the display improves the programming speed of the
	instrument.
NOTE	*RST switches the display back on.
Example	DISP OFF	Switch off the frontpanel display
