i am using the E3631A with labview.
the driver was plug and play driver download from NI.
the driver query syst:err? for almost all command it sent to the power supply.
that's not a problem if the communication was fast.
my problem now is that the E3631 takes ~1 second to response. (worst case)
normal communication takes less than 5ms.
and even syst:err? takes only less than 100ms.
but ocationally it takes ~1second.
is there a way to speed up the syst:err? query ?
or is there a driver that actually do not sent this after every command ?
