3.4 Data
• If a value outside the setting 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.
<Voltage>, <Time>, <Frequency>, <Current>
<Voltage>, <Time>, <Frequency>, and <Current>
indicate decimal values that have physical significance.
A <Multiplier> or <Unit> can be attached to the <NRf>
form that was described earlier. The following types of
expressions are possible.
Form Example
<NRf><Multiplier><Unit>
5MV
<NRf><Unit>
5E-3V
<NRf><Multiplier>
5M
<NRf>
5E-3

• <Unit>
<Units> that you can use are indicated in the
following table.
Symbol Word Description
V Volt Voltage
S Second Time
HZ Hertz Frequency
MHZ Megahertz Frequency
A Ampere Current
• <Multiplier> and <Unit> are not case sensitive.
• “U”isusedtoindicatemicro(“μ”).
• “MA” is used for Mega to distinguish it from Milli.
Megahertz, which is expressed as “MHZ,” is an
exception. Therefore, “M (Milli)” cannot be used for
frequencies.
• If both <Multiplier> and <Unit> are omitted, the
default unit is used.
• Response messages are always expressed in the
<NR3> form. Response messages are returned using
the default unit without the <Multiplier> or <Unit>.
Data
Data contains conditions and values that are written
after the header. A space separates the data from the
header. Data is grouped as follows:
Data Description
<Decimal> A value expressed in decimal notation
Example: Probe attenuation for CH1
-> CHANnel1:PROBe 100
<Voltage><Time><Frequency><Current>
A physical value
Example: Time-axis range
-> TIMebase:TDIV 1US
<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 input coupling of CH1
-> CHANnel1:COUPling {AC|DC|
GND|TC}
<Boolean> Indicates on and off. Specify ON, OFF,
or a value
Example: Turn on the CH1 display
-> CHANnel1:DISPlay ON
<String data> User-defined string
Example: Comment attached to screen
data output
-> HCOPy:COMMent "ABCDEF"
<Filename> Indicates a file name.
Example: Save file name
-> FILE:SAVE:NAME "CASE1"
<Block data> Data that contains 8-bit values
Example: Response to acquired
waveform data
-> #800000010ABCDEFGHIJ
<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 Description Examples
<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 form from <NR1> to <NR3>
• The instrument can receive decimal values that are
sent from the controller in any form, from <NR1> to
<NR3>. This is expressed as <NRf>.
• The 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.
