SCPI Instrument Command List

Description Use this command to set the type of the segment for one channel.

If the segment type of one channel is set to PRBS the other channel may not be set to DATA.

If at least one channel uses PRBS, then the segment type combination used in this segment has to be used in every segment that shall generate a PRBS.

Command	:DIG:PATT:UPD
Long	:DIGital[:STIMulus]:PATTern:UPDate
Form	Set & query
Parameter	ON OFF ONCE
*RST value	ON
Description	Use this command to enable and disable the automatic updating of the
	pattern generating hardware following a
	:DIG:PATT:SEGM[1234]:DATA command. Disable the automatic
	updating if you want to set up new pattern data in the instrument without
	affecting the pattern which is currently being generated. You can then
	update the hardware with the new pattern data by sending a
	:DIG:PATT:UPD ONCE command.

Command	:DIG:SIGN[12]:FORM
Long	:DIGital[:STIMulus]:SIGNal[12]:FORMat
Format	Set & Query
Parameter	RZ NRZ R1
Range Coupling	Period, Frequency
*RST value	RZ
