<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
Example
<NRf>
1
#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>
#Q777
#B<Binary value made up of the digits 0 and 1>
#B001100
• <Register> is not case sensitive.
• Response messages are always expressed as
<NR1>.
<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, refer to “Header Interpretation
Rules” on page 4-4.
Form
Example
{AC|DC|GND}
AC
• 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
Example
{ON|OFF|<NRf>}
ON OFF 1 0
• 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.
<Voltage>, <Time>, <Frequency>, and <Current>
<Voltage>, <Time>, <Frequency> , and <Current>
indicate decimal values which have physical
significance. <Multiplier> or <Unit> can be attached to
<NRf>. They can be entered in any of the following
forms.
Form
Example
<NRf><Multiplier><Unit>
5MV
<NRf><Unit>
5E-3V
<NRf><Multiplier>
5M
<NRf>

• <Multiplier> and <Unit> are not case sensitive.
•
"U"
is used to indicate
"
µ
."
•
"MA"
is used for Mega (M) to distinguish it from
Milli, except for in the case of Megahertz, which is
expressed as
"MHZ."
Hence, it is not permissible
to use
"M"
(Milli) for Hertz.
• 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.
