HP and ML4803 emulation commands on the other hand, do not have to have a
space between the command header and the parameter, or commas between
the parameters.
The format for HP emulation commands is:
<command header><parameter 1><parameter
n
>...
The end of the command text must be terminated with either a line feed character
(0Ah, decimal 10) or a GPIB End of Transmission State (EOI), or both.
Data input and output formats and templates referred to throughout this chapter
are delimited with the less-than and greater-than characters (< >). Optional pa
-
rameters and suffix characters are delimited with brackets ([ ]). These characters
are not part of the data and are only used in this text to distinguish the data ele
-
ments they represent.
All the commands which allow a level to be set as a value argument are floating
point values which can use the E-0x convention or a suffix multiplier. The GPIB
standard [units] convention (i.e., MS for milliseconds, etc.) IEEE codes and for-
mats have been implemented for the suffix units and multipliers. The suffix unit is
always allowed but is not required and is shown in brackets where appropriate.
Table 6-1 lists the numeric data suffix mnemonics for the ML2430A Series Power
Meter. These mnemonics are used when entering numeric data with GPIB com-
mands (use of these codes is optional).
Commands which are not floating point, but integer, are:
