10.4 Data
<Voltage>, <Current>, <Resistance>,
<Temperature>, and <Time>
<Voltage>, <Current>, <Resistance>, <Temperature>,
and <Time> indicate decimal values that have physical
significance. A <Multiplier> or <Unit> can be attached
to the form that was described earlier. Use one of the
following syntaxes.
Syntax Example
<NRf><Multiplier><Unit>
5MV
<NRf><Unit>
5E-3V
<NRf><Multiplier>
5M
<NRf>
5E-3
<Multiplier>
Multipliers that you can use are indicated in the
following table.

<Unit>
Units that you can use are indicated in the following
table.
Symbol Word Meaning
V
Volt Voltage
A Ampere Current
OHM
Ohm Resistance
CEL
Celsius Temperature °C
FAR
Fahrenheit Temperature °F (only on models
with the -UF suffix code)
S Second Time
• <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.
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 Meaning
<Decimal> A value expressed in decimal notation
<Voltage><Current>
<Resistance>
<Temperature>
<Time> A physical value
(Example: Voltage range setting
->:SOURce:RANGe 30V
<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: Select the source function
-> :SOURce:FUNCtion {VOLTage|
CURRent}
)
<Boolean> Indicates on and off. Specify ON, OFF, or a
value.
(Example: Turn the output on.
->:OUTPut:STATe ON
)
<String Data> User-defined string
(Example: Ethernet IP address setting
-> :SYSTem:COMMunicate:ETHernet:
IP "192.168.0.1"
)
<Block Data> Data that contains 8-bit values
<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>
• The 2553A can receive decimal values that are sent
from the controller in any of the forms <NR1> to
<NR3>. This is expressed as <NRf>.
• The 2553A 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.
• If a value has more significant digits than are
available, the value will be rounded.
