GPIB Operational Capabilities
On the network analyzer's rear panel, next to the GPIB connector, there is a list of GPIB
device subsets as defined by the IEEE 488.2 standard. The analyzer has the following
capabilities:
These codes are completely explained in the IEEE Std 488 documents, published by:

GPIB Status Indicators
When the analyzer is connected to other instruments over the GPIB, the GPIB status
indicators illuminate to display the current status of the analyzer. The GPIB status
indicators are located in the instrument-state function block on the front panel of the
network analyzer.
R = Remote Operation
L = Listen mode
T = Talk mode
S = Service request (SRQ) asserted by the analyzer
