Preventing GPIB Bus Lockup
GPIB bus lockup is a condition where the GPIB bus and the Active Controller handshake
are in a temporary holdoff state while the Active Controller waits to read the measurement
result from the Test Set.
This Test Set has a feature that allows the bus to be released automatically when a
measurement cycle is unsuccessful. It is called Indefinite Measurement and is
automatically ON when the Test Set is powered on and causes the Test Set to send the
number +1.7976931348623157 e+308 for real number measurements, and 2147483647
for integer number measurements.
