E5810 Operation Hangs

There are two additional network checks you may encounter: E5810 operation hangs or SICL timeout is set to 0 (infinite)

The E5810 has a single Remote IO Server servicing both GPIB and RS-232 interfaces. Thus, if either interface “hangs” in an operation where a timeout has been set to a long time period, there is no more communication on either interface (GPIB or RS-232) until the pending transaction completes (via normal completion, or a timeout). That is, a pending operation on the RS-232 interface will hang GPIB operations, and vice-versa.

To avoid this, set as short a timeout as possible for both the GPIB and RS-232 interfaces, so the E5810 is not left in a hung situation awaiting a pending I/O operation. For example, a detached (or loose) GPIB or RS-232 cable can cause an operation to hang if timeouts are set too high.

Setting long timeouts with the E5810 is not recommended. However, if a long timeout period is required for your programming application, you can set the timeout with:

VISA: viSetAttribute() and VI_ATTR_TMO_VALUE attribute

SICL: itimeout()

See the Agilent VISA User’s Guide for a description of the VISA command. See the Agilent SICL User’s Guide for Windows for a description of the SICL command.
