• <Multiplier> and <Unit> are not case sensitive.
• "U" is used to indicate "µ".
• "MA" is used for Mega (M) to distinguish it from Mili.
However, when using "MA" for current, Mili-ampere
will be valid; therefore use "MAA" to assign Mega-
ampere.
• If both <Multiplier> and <Unit> are omitted, the
default unit will be used.
• Response messages are always expressed in
<NR3> form. Neither <Multiplier> nor <Unit> is
used, therefore the default unit is used.
<Register>
<Register> indicates an integer, and can be expressed
in hexadecimal, octal or binary as well as as a decimal
number. <Register> is used when each bit of a value
has a particular meaning. <Register> is expressed in
one of the following forms.
Form
<NRf>
#H<Hexadecimal value made up of the digits 0 to 9, and A to F> #H0F
#Q<Octal value made up of the digits 0 to 7>
#B<Binary value made up of the digits 0 and 1>
• <Register> is not case sensitive.
• Response messages are always expressed as
<NR1>.
14-8
<Character Data>
<Character data> is a specified string of character data
(a mnemonic). It is mainly used to indicate options, and
is chosen from the character strings given in { }. For
interpretation rules, see "Header Interpretation Rules"
on page 14-6.
Form
{RMS|VMEan|DC}
• As with a header, the "COMMunicate:VERBose"
command can be used to return a response
message in its full form. Alternatively, the
abbreviated form can be used.
• The "COMMunicate:HEADer" command does not
affect <character data>.
<Boolean>
<Boolean> is data which indicates ON or OFF, and is
expressed in one of the following forms.
Form
{ON|OFF|<NRf>}
• When <Boolean> is expressed in <NRf> form, OFF
is selected if the rounded integer value is "0" and
ON is selected if the rounded integer is "Not 0".
• A response message is always "1" if the value is ON
and "0" if it is OFF.
<Character String Data>
<Character string data> is not a specified character
string like <Character data>. It is an arbitrary character
string. A character string must be enclosed in single
quotation marks (
Form
<Character string data>
• Response messages are always enclosed in double
quotation marks.
Example
1
• If a character string contains a double quotation
mark ("), the double quotation mark will be replaced
#q777
by two concatenated double quotation marks ("").
#B001100
This rule also applies to a single quotation mark
within a character string.
• <Character string data> is an arbitrary character
string, therefore this instrument assumes that the
remaining program message units are part of the
character string if no single (') or double quotation
mark (") is encountered. As a result, no error will be
detected if a quotation mark is omitted.
Example
