Communication Method
Data formats
The device uses character data and decimal numeric data depending on the command.
(1) Character data
Character data always begins with an alphabetic character, and subsequent characters may be
either alphabetic or numeric. Character data is not case-sensitive, although response messages
from the device are only upper case.
Like command syntax, the data can be in long or short form and can be received in either form.
Example:
:SYSTEM:MODULE:WIRE:MODE 1 WIRE2
(2) Decimal numeric data
Three formats are used for numeric data, identified as NR1, NR2, and NR3. Numeric values may
be signed or unsigned. Unsigned numeric values are handled as positive values.
Values exceeding the precision handled by the device are rounded to the nearest valid digit.
• NR1 integer data (example: +12, −23, 34)
• NR2 fixed-point data (example: +1.23, −23.45, 3.456)
• NR3 floating-point exponential representation data (example: +1.0E-2, −2.3E+4)
The term “NRf format” includes all three of the above numeric decimal formats.
The device accepts NRf format data.
The format of response data is specified for each command, and the data is sent in that format.
Example:
:STAT:QUES:ENAB 106
:IO:PULSE:TIME 0.001
