3.4 Data

Data
A data section comes after the header. A space must
be included between the header and the data. The
data contains conditions and values. Data is classified
as below.
Data Description
<Decimal> Value expressed as a decimal number
(Example: The number of measurement
samples
-> :SAMPle:GATE:EVENtsize 100)
<Voltage><Time> Physical value
<Frequency> (Example: Gate time
-> :SAMPle:GATE:TIME 1US)
<Percentage>
<Register> Register value expressed as either binary,
octal, decimal or hexadecimal.
(Example: Extended event register value
-> :STATUS:EESE #HFE)
<Character data> Predefined character string (mnemonic).
Can be selected from { }
(Example: Gate mode selection ->
:SAMPle:GATE:MODE {EVENt|TIME|
EXTernal})
<Boolean> Indicates ON and OFF. Set to ON, OFF or
value
(Example: Turn ON panorama display
-> :DISPlay:PANorama:STATe ON)
<Character string data> Arbitrary character string
(Example: Name of the file to be deleted
-> :FILE:DELete:SETup "SETUP_1")
<Block data> Arbitrary 8-bit data
(Example: Response to acquired measured
data -> #6000010ABCDEFGHIJ)
<Decimal>
<Decimal> indicates a value expressed as a decimal
number, as shown in the table below. Decimal values are
given in the NR form as specified in the ANSI X3.42-1975.
Symbol Description
<NR1> Integer
<NR2> Fixed-point number
<NR3> Floating-point number
<NRf> Any of the forms <NR1> to <NR3> is allowed.
• The instrument can receive decimal values that are
sent from the controller in any of the forms, <NR1>
to <NR3>. This is represented by <NRf>.
• For response messages that the instrument returns
to the controller, the form (<NR1> to <NR3> to be
used) is determined by the query. The same form is
used regardless of the size of the value.
• In the case of <NR3>, the "+" after the "E" can be
omitted, but the "–" cannot.
• If a value outside the setting range is entered, the
value will be normalized so that it is just inside the
range.
• If a value has more significant digits than the
available resolution, the value is rounded.
IM 704510-17E
<Voltage>, <Time>, <Frequency>, <Percent>
<Voltage>, <Time>, <Frequency>, and <Percent>
indicate decimal values that have physical significance.
Except for <Percent>, a <Multiplier> or <Unit> can be
attached to <NRf>. They can be entered in any of the
following forms.
• <Multiplier>
• <Unit>
Example
• <Multiplier> and <Unit> are not case sensitive.
125 -1 +1000
125.0 -.90 +001. • "U" should be used in place of "µ" in the data.
125.0E+0 -9E-1 +.1E4
• "MA" is used for Mega to distinguish it from Milli.
• If both <Multiplier> and <Unit> are omitted, the
• Response messages are always expressed in the
Form Example
<NRf><Multiplier><Unit> 5MV
<NRf><Unit> 5E-3V
<NRf><Multiplier> 5M
<NRf> 5E-3
