E5810B operation hangs

The E5810B has a single remote IO server servicing the

GPIB, USB, and RS- 232 interfaces. If one of the interface

hangs in an operation where a timeout has been set to a

long time period, there is no more communication on the

interface until the pending transaction completes (via normal

completion, or a timeout). That is, a pending operation on

the RS- 232 interface will stall the GPIB or USB operations,

and vice- versa.

To avoid this, set a short timeout for the GPIB, USB, and

RS- 232 interfaces, so that the E5810B is not left in a hung

situation awaiting a pending I/O operation. For example, a

detached or loose GPIB, USB, or RS- 232 cable can cause an

operation to stall if timeouts are set too high.

Setting long timeouts with the E5810B is not recommended.

However, if a long timeout period is required for your

programming application, you can set the timeout with these

commands:

VISA: viSetAttribute() and VI_ATTR_TMO_VALUE

attribute

SICL: itimeout()

Refer to the Keysight VISA User’s Guide and the Keysight

SICL User’s Guide for a description of the VISA command

and SICL command respectively.
