GPIB Interface
Each device on the GPIB (IEEE-488) interface must have a unique address.
You can set the instrument’s address to any value between 0 and 30.
The address is set to “9” when the instrument is shipped from the factory.
• Your computer’s GPIB interface card has its own address. Be sure to
avoid using the computer’s address for any instrument on the interface
bus.
• The GPIB address is stored in non-volatile memory, and does not
change when power has been off, after a Factory Reset (
*RST
command), or after an Instrument Preset (SYSTem:PRESet command).
Front Panel Operation: Utility > REMOTE I/O > GPIB > GPIB ADDRESS
To set the GPIB address, turn the knob (or use the number keypad)
to select the desired address.
Remote Interface Operation: SYSTem:COMMunicate:GPIB:ADDRess
USB Interface
For the USB interface, no configuration parameters are required to set up
the instrument. Connect your instrument to a USB port on your computer.
Note that it may take several seconds for the computer to recognize and
establish a connection to the instrument.
LAN Interface
By default, DHCP is enabled on the instrument, which may enable network
communication over the LAN interface. You may need to set several
configuration parameters as described in this section.
