column, you can click the applicable button to perform these
actions for the device.

Read the Status Byte for IEEE-488.2 compliant devices (Read STB)
Return a System Error for SCPI compliant devices (SYST:ERR?)
In addition, you can clear the display on the screen by clicking the

button, set the timeout value (in seconds) by typing in the desired

Timeout (sec) dialog box, or clear all pending operations on
instruments connected to the E5810 by clicking the

NOTE
To program instruments using VISA, VISA COM, SICL, or Agilent VEE,
you must install and configure the Agilent IO Libraries Suite on your PC
(see Chapter 2 - Installing the E5810).
For VISA programming information, see the Agilent VISA User’s Guide. If
the Agilent IO Libraries Suite is installed, you can access an electronic
version of the manual by clicking the blue IO icon on the taskbar and then
clicking
Documentation | VISA Users Guide. The same Documentation
menu also includes VISA COM and SICL information.
NOTE
These buttons will work only if the selected instrument supports
IEEE 488.2 and/or SCPI command sets.
