if value is 0x8000000, error is in SCPI syntax or other errors relating to instrument setability .SCPI
error list is given in the SCPI Commands reference.
If value is larger than 0x8000000, look for problems in the communication with the PXA125. Most
probable cause for such errors is not invoking the Arb Detector program after you power up your
computer.
Description
The SendCommand() function is the main function you'll use for controlling instrument
functions and parameters. The PXA125 is using Standard Commands for Programmable
Instruments (SCPI). The following paragraphs describe SCPI syntax, structure and format. In
general, you can program the instrument by sending one command at a time. However, the
inbuf has a capacity to accept up to 256-character strings.
Using SCPI language should look familiar to programmers that use to program GPIB or VXI
