5.4 Data
• If a value has more significant digits than are
available, the value will be rounded.
<Voltage>, <Current>, and <Time>
<Voltage>, <Current>, and <Time> indicate decimal
values that have physical significance. A <Multiplier> or
<Unit> can be attached to the form that was described
earlier. The following types of expressions are possible.
Form Example
<NRf><Multiplier><Unit>
5MV
<NRf><Unit>

• <Multiplier> and <Unit> are not case sensitive.
• “U” is used to indicate micro (”μ”).
• “MA” is used for Mega to distinguish it from Milli.
However, “MA” is interpreted as milliampere for
current.
• If both <Multiplier> and <Unit> are omitted, the basic
unit (V, A, or S) is used.
• Response messages are always expressed in the
<NR3> form. Additionally, they are returned in the
basic form, without a multiplier or unit attached.
Data
Data contains conditions and values that are written
after the header. A space separates the data from the
header. Data is classified as follows:
Data Description
<Decimal>
A value expressed in decimal notation
(Example: VT ratio setting
->[:INPut]:SCALing:VT 100)
<Voltage><Current> A physical value
<Time>
(Example: Voltage range setting
->[:INPut]:VOLTage:RANge 150V)
<Register>
A register value expressed as binary, octal,
decimal, or hexadecimal
(Example: Extended event register value
->:STATUS:EESE #HFE
)
<Character data>
Predefined character string (mnemonic).
Select from the available strings in braces.
(Example: Measurement mode selection
->[:INPut]:MODE {RMS|VMEan|DC})
<Boolean>
Indicates on and off. Specify ON, OFF, or a
value.
(Example: Turning data hold on
->:HOLD ON
)
<String data>
An arbitrary character string
(Example: Model code response
->:SYSTEM:MODEL "WT310E")
<Block data>
Data that contains 8-bit values
(Example: Measured data (binary format)
response
-> #40012ABCDEFGHIJKL
)
<Decimal>
<Decimal> indicates a value expressed as a decimal
number, as shown in the table below. Decimal values
are written in the NR form as specified in ANSI
X3.42-1975.
Symbol Meaning
Example
<NR1>
Integer
125
-1 +1000
<NR2>
Fixed-point number
125.0
-.90 +001.
<NR3>
Floating-point number
125.0E+0 -9E-1 +.1E4
<NRf>
Any of the forms <NR1> to <NR3>
• This instrument can receive decimal values that are
sent from the controller in any of the forms <NR1>
to <NR3>. This is expressed as <NRf>.
• This instrument returns a response to the controller
in one of the forms from <NR1> to <NR3>
depending on the query. The same form is used
regardless of the size of the value.
• For the <NR3> form, the plus sign after the “E” can
be omitted. You cannot omit the minus sign.
• If a value outside the range is entered, the value is
adjusted to the closest value within the range.
