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.
