Using E5810 Web Access
Finding and Querying Instruments
Button
Description
*IDN?
ID String.
Returns the ID string for the selected IEEE-488.2 compliant
instrument.
Device Clear
Device Clear.
Sometimes communication with an instrument may be
impeded. This can occur for a wide variety of reasons. Sending a
Device
Clear
to the instrument usually solves this problem and restores
proper communication with the instrument. If you encounter an error while
doing a Formatted I/O operation, you can send a
Device Clear
to ensure
proper instrument communication is restored.
Read STB
Read Status Byte.
Returns the decimal and hexadecimal value of the
IEEE-488.2 compliant instrument's Status Byte. Many instruments that
support Formatted I/O also have the ability to read the Status Byte. This
returns information on the status of the instrument, such as error status
and/or busy status. See your instrument manuals for status byte codes.
SYST:ERR?
System Error.
Returns a SCPI system error for a SCPI compliant
instrument. A“0 No errors” return is sent to show no system errors.
Clear History
Clear the Display
. Clears the (History) display of all previous queries.
Clear ALL
Pending
Operations
Clear All Pending Operations.
Clears all pending operations on instruments
connected to the E5810. This operation expires all existing timeouts on all
devices connected to the E5810. Taking this action may affect other users
currently using the E5810. A password dialog box will appear that asks you
if you really want to do this action.
Timeout
Change instrument Timeout.
A timeout value is used to limit the amount of
time for an I/O operation to complete. The I/O Timeout value, as set on the
Configuring your E5810 LAN/GPIB Gateway
page, may not be long enough
for some instrument activities to complete. Setting a longer timeout here
tells the E5810 to wait a longer time for the instrument to finish.
As an alternative, doing a separate
Send
and
Receive
may also work.
Also, if the configuration value is too long, you may force a shorter timeout
here for faster troubleshooting of instrument tests, etc. To set a different
timeout, enter a Timeout value in the
Timeout
text box. This value is used
for all commands issued to an instrument from this page. The valid timeout
range is 1 to 60 seconds.
