HP and ML4803 em u la tion com mands on the other hand, do not have to have
a space be tween the com mand header and the pa ram e ter, or com mas be tween
the pa ram e ters.
The for mat for HP em u la tion com mands is:
<com mand header><parameter 1><parameter n>...
The end of the com mand text must be ter mi nated with ei ther a line feed char -
ac ter (0Ah, dec i mal 10) or a GPIB End of Trans mis sion State (EOI), or both.
Data in put and out put for mats and tem plates re ferred to through out this
chap ter are de lim ited with the less-than and greater-than char ac ters (< >).
Op tional pa ram e ters and suf fix char ac ters are de lim ited with brack ets ([ ]).
These char ac ters are not part of the data and are only used in this text to dis -
tin guish the data el e ments they rep re sent.
All the com mands which al low a level to be set as a value ar gu ment are float -
ing point val ues which can use the E-0x con ven tion or a suf fix mul ti plier. The
GPIB stan dard [units] con ven tion ( i.e., MS for mil li sec onds, etc.) IEEE codes
and for mats have been im ple mented for the suf fix units and mul ti pli ers. The
suf fix unit is al ways al lowed but is not re quired and is shown in brack ets
where ap pro pri ate.
Ta ble 6- 1 lists the nu meric data suf fix mne mon ics for the ML2400A Se ries
Power Me ter. These mne mon ics are used when en ter ing nu meric data with
GPIB com mands (use of these codes is op tional).
