cannot be sent with a query. IEEE-488.2 commands do not have query counterparts
unless explicitly shown with a question mark appended.
7. Parameters for a command must be separated from the command itself using a
<space>
character (0h20).
8. IEEE-488.2 commands start with an asterisk ( * ) and are not case sensitive.
9. All numerical values are ASCII encoded decimal strings consisting of 1 or more ASCII
digits. 8 and 16 bit register values are binary weighted values represented by an ASCII
string of 1 or more decimal digits.
10. Multiple Commands and Queries as part of the same program message string are NOT
supported. The term 'program message' refers to a continuous string.
11. Multiple data parameter names and values must be separated by commas.
12. 'Multiple key word' messages may be sent without duplicating the first level SCPI
keyword (i.e., OUTPut).
e.g., OUTPut:COUNt_20;TINTerval_200 (space shown as “_”)
13. A keyword is a single word beginning with a colon (:).
14. Program Messages MUST be terminated with a Line Feed (0Ahex, 10dec) or a Carriage
Return (0h0D, 13dec) character. This is referred to as an end-of-string <eos>. Further
SCPI commands shall begin with a first level keyword (i.e.,:SOURce:).
15. All values shown in angle brackets <> are examples of real values used with commands
but labels are sometimes used to indicate a variable which is not known until actual
time of use.
16. Units shown after the angle bracketed value are not to be included inside the value, but
are shown as a reference to the units. The angle brackets are not part of the value.
17. Command strings may contain spaces.
18. The battery element tester interface accepts IEEE-488.2 NR1, NR2 and NR3 numeric
formats. Most query responses are NR1 or NR2 types. i.e., NR1=120, NR2=120.0,
NR3=1.2E+02.
