SCPI Commands – an Introduction
62 Series N5700 User’s Guide
Parameter Types
Data programmed or queried from the power supply is ASCII. The
data may be numerical or character string.
Numeric Parameters
Symbol Response Formats
<NR1> Digits with an implied decimal point assumed at the right of the
least-significant digit. Examples: 273
<NR2> Digits with an explicit decimal point. Example: .0273
<NR3> Digits with an explicit decimal point and an exponent. Example:
2.73E+2
Parameter Formats
<NRf> Extended format that includes <NR1>, <NR2> and <NR3>.
Examples: 273 273. 2.73E2
<NRf+> Expanded decimal format that includes <NRf> and MIN
MAX. Examples: 273 273. 2.73E2 MAX.
MIN and MAX are the minimum and maximum limit values that
are implicit in the range specification for the parameter.
<Bool> Boolean Data. Example: 0 | 1 or ON | OFF
Discrete and String Parameters
Symbol Response Formats
None
Discrete parameters are used to program settings that have a limited
number of values (like RST, RCL0, BUS). You can mix upper- and
lower-case letters. Query responses will always return the short form
in all upper-case letters
“string”
String parameters can contain virtually any set of ASCII characters. A
string must begin and end with matching quotes; either with a single
quote or a double quote. You can include the quote delimiter as part of
the string by typing it twice without any characters in between.
