GPIB & Remote Programming
The CP2020 features comprehensive GPIB control capabilities:
-
Talker/Listener Functions: Can send setting or instrument data over the bus (talker) and receive commands from a controller (listener)
-
IEEE Compliance: Conforms to IEEE488.1 and IEEE488.2 specifications
-
HS488 Capable: High-speed GPIB transmission up to 8 MB/s
-
Programmable GPIB Command Set: Command set can be modified to match other equipment, saving time in controller code changes
-
Compatibility Modes: Command set compatible with CP2020; emulation modes available for CP92, CP91, and CP82 control processors
-
GPIB Address: Factory default setting is 4 (restorable via Preset function)
The GPIB uses a party-line bus structure where up to 15 devices can be connected on one continuous bus . Every byte transferred undergoes a handshake to ensure valid data is received .
