Using and Troubleshooting the GPIB-VXI/C

A16?

Purpose: Read word value from VXI A16 address space.

Query Syntax: A16? <A16 address>

Response: Program response:

<word value><CRLF>

Console response:

Value <hex word value> (<word value>) read from A16 address <A16 hex address> (<A16 address>)<CRLF>

where <word value> is in decimal integer format, <hex word value> is in C language hexadecimal format, <A16 hex address> is in C language hexadecimal format, and <A16 address> is in decimal integer format.

For example, if you want to read the ID register (configuration register) of logical address 19, you would have to specify the A16 address (RREG? Command requires only the offset).
