4.4 Data
<Voltage>, <Current>, <Time>, <Frequency>
<Voltage>, <Current>, <Time> and <Frequency>
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
5E-3V
<NRf><Unit>
5M
<NRf><Multiplier>
5E-3
<NRf>
<Multiplier>

<Unit>

V

A

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

<Register>
<Register> indicates an integer, and can be expressed
in hexadecimal, octal or binary as well 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>
#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>.
<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
{AUTO|NORMal}
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 (') or double quotation
marks (").
Form
<Character string data>
Response messages are always enclosed in double
quotation marks.
