Remote ControlParameter:In the parameter column the required parameters and their range of valuesare stated.Unit:The unit column shows the basic unit of the physical parameters.Indentations. The various levels of the SCPI command hierarchy are shown inthe table by indentations to the right. The lower the level, the greater theindentation to the right. It should be noted that the complete notation of thecommand includes the higher levels too.In the individual command description, the hierarchy is represented accordingly.This means that for each command all keywords above up to the left-mostposition have to be considered too.Upper/lower case. Uppercase/lowercase characters are used to differentiatebetween the long form and the short form of the keywords of a command in thecommand description (refer to Command Structure on page 3–5). Theinstrument does not differentiate between uppercase and lowercase characters.Special characters.| A vertical bar in the notation of the parameters is used to separatealternative options and is to be understood as an “or”. The effect of thecommand differs according to the parameter stated.[ ] Keywords in square brackets may be omitted in compound headers (referto Optional keywords on page 3–7). For compatibility with the SCPIstandard, the instrument must be able to recognize the full length of thecommand.Parameters in square brackets may also be optionally inserted into thecommand or omitted.Common CommandsThe common commands are based on the IEEE 488.2 (IEC 625.2) standard. Aspecific command has the same effect in different instruments. The headers ofthese commands consist of an asterisk (*) followed by three letters. Manycommon commands refer to the status reporting system described in detail onpage 3–19.3–12 DDS200 Digital Demodulation System User Manual
