Overlapped Commands
Commands that require more time to execute than normal. The
command *WAI can be used after the overlapped command to tell
the calibrator to wait until the command finishes before executing the
next command. For example:
TRIG; *WAI
Triggers the pulse train. Once the pulse train has been triggered, the
calibrator can proceed to the next command.
Sequential Commands
Commands that are executed immediately after the are entered. This
type includes most of the commands.
7.3-2 Character Processing
The data entered into the calibrator is processed as follows:
• ASCII characters are discarded if their decimal equivalent is less
than 32 (space), except 10 (LF) and 13 (CR):
• Data is taken as 7-bit ASCII
• The most significant data bit is ignored.
• Upper or lower case is acceptable.
7.3-3 Response Data Types
The data returned by the calibrator can be divided into four types:
Integer
For most computers and controllers they are decimal numbers
ranging from -32768 to 32768. For example:
*ESE 140; *ESE? returns 140
Floating
Numbers that have up to 15 significant figures and exponents. For
example:
CPRT_COEFA? returns 3.908000E-03
Character Response Data (CRD)
Data returned as keywords. For example:
RTD_TYPE? returns PT385_10
