STANDARDS INFORMATION

D.1 SCPI Conformance Information

All commands comply to the SCPI standard 1994.0, except for the following:

-The *RST condition of the SENSe:VOLTage<n>[:DC]:RANGe:AUTO ON OFF command.

Exception:

After *RST, autoranging MTB is switched off.

-The *RST condition of the SENSe:SWEep:TIME:AUTO ON OFF command.

Exception: After *RST, autoranging attenuators CH1, CH2, CH3, and CH4 are switched off.

-The <device> parameter of the HCOPy:DEVice <type> command.

Exception: The HCOPy:DEVice command allows to select the hardcopy device by specifying its name or type number, e.g., <type> = HPLASER or LQ1500.

In addition, the following commands are implemented:

-The CALCulate:TRANsform:FREQuency:TYPE ABSolute RELative command.

Purpose:

To allow the selection of absolute or relative FFT calculation.

-The TRIGger[:SEQuence[1] STARt]:VIDeo:FORMat[:TYPE] <type> command.

Purpose:	To allow the selection of a TV standard by specifying its name
	or abbreviation, e.g., <type> = HDTV.

-The SYSTem:SET? <node_number> query.

Purpose:	To allow the instrument settings to be saved and restored in
	functional groups (nodes) as specified by the <node_number>.
