Installation
3. Communicate with the instrument attached to
the adapter using the control program running
on your GPIB controller.
The following parameter assumptions are made:
GPIB secondary addressing is not supported.
The defau lt GPIB primary address is 1. The GPIB primary address can only be changed from a connected Tektronix
USBTMC-USB488 compliant instrument designed to support the TEK-USB-488 GPIB to USB Adapter, such as a DPO4000
Series oscilloscope.
The GPIB Program Message Terminator (PMT) is the GPIB end of input (EOI) line and is not configurable. Messages that
assert EOI concurren t with a new line (hexadecimal 0a) character as the last data byte a re supported. This means that both
EOI a nd EOI NL program message terminations are supported and that the NL-only termination is not suppo rted.
USB hubs are not supported. You can connect only one USBTMC-USB488 compliant instrument to the USB Host port
of th e adapter at any time.
The GPIB on/off state is online when there is an active USBTMC-USB488 connection. You cannot change the GPIB on/off
state after the connection is established.
