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> A physical value
<Frequency> (Example: Time-axis range
-> TIMebase:TDIV 1US )
<Current>
<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|DC50|GND} )
<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
-> MATH1:UNIT:USERdefine "VOLT" )
<Filename> Indicates a file name.
(Example: Save file name
-> FILE:SAVE:WAVeform: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
<NR1> Integer
<NR2> Fixed point number
<NR3> Floating-point number
<NRf> Any form from <NR1> to <NR3>
• The DLM4000 can receive decimal values that are
sent from the controller in any form, from <NR1> to
<NR3>. This is expressed as <NRf>.
• The DLM4000 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 setting range is entered, the
value is adjusted to the closest value within the
range.
4-6
Example
125 -1 +1000
125.0 -.90 +001.
125.0E+0 -9E-1 +.1E4
• 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.
Format
<NRf><Multiplier><Unit>
<NRf><Unit>
<NRf>
<Multiplier>
<Multipliers> that you can use are indicated in the
following table.
Symbol Word
EX Exa
PE Peta
T Tera
G Giga
MA Mega
K Kilo
M Milli
U Micro
N Nano
P Pico
F Femto
A Atto
<Unit>
<Units> that you can use are indicated in the following
table.
Symbol Word
V Volt
S Second
HZ Hertz
MHZ Megahertz
A Ampere
• <Multiplier> and <Unit> are not case sensitive.
• "U" is used to indicate micro ("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>.
