Appendix D - DS-100C Technical Specifications for details on measurement
ranges.
Multiple Current Ranges
The standard DS-100C includes two current ranges, 10 Amperes and 100
Amperes. Before a I-V curve is taken, you may select one of these two ranges
using IVPC. You will not damage the DS-100 by inadvertently selecting the low
range when the high range is required. However, the displayed I-V curve will not
include current values higher than 10 Amperes.
External Command Set
Typically the IVPC program controls the DS-100C, however you can write your
own program if necessary. Some users may want to write software to perform
custom tracer operations. This is possible using the following commands sent to
the DS-100C through its RS-232 serial or USB control ports.
The DS-100C sends a prompt character “>” when it is ready to receive a
command line. Commands should only be sent to the DS-Tracer after receiving
this prompt. Each command has a unique one character start code, indicating
the type of command, followed by comma-delineated parameters as required.
After receiving a command line, the DS-Tracer attempts to perform the
requested operation. If the command and its parameters can be decoded
properly, the DS-Tracer sends a “*” followed by a carriage return (ASCII 0DH) to
indicate that the command was accepted. If the command was not accepted, the
DS-Tracer will return an error line in place of the “*” line . It is this return line that
should be checked following all commands. Refer to Appendix B DS-Tracer
ERROR CODES for a list of error messages. Each command of the DS-Tracer is
described below with an example of a proper command line and responses from
the DS-Tracer.
Note: Optional parameters are shown with brackets [].
