Status Reporting

Serial Poll

Serial Poll
The HP 16500B Logic Analysis System supports the IEEE 488.1 serial poll
feature. When a serial poll of the instrument is requested, the RQS bit is
returned on bit 6 of the status byte.
Using Serial Poll (HP-IB)
This example will show how to use the service request by conducting a serial
poll of all instruments on the HP-IB bus. In this example, assume that there
are two instruments on the bus: the logic analyzsis system at address 7 and a
printer at address 1.
The program command for serial poll using HP BASIC 6.2 is Stat =
SPOLL(707). The address 707 is the address of the logic analysis system in
the this example. The command for checking the printer is Stat =
SPOLL(701) because the address of that instrument is 01 on bus address 7.
This command reads the contents of the HP-IB Status Register into the
6–7
