GPIB Address Conflict Checker
Enter the known values and run the calculation.
Enter one instrument per line. Use instrument name, address if you want the exported map to stay readable, or enter just the numeric address when you only need a quick conflict check.
The output table calls out duplicates, out-of-range addresses, and valid entries. Export buttons give you a CSV file and a plain-text bench sheet.
Overview
Identify conflicting GPIB addresses before a multi-instrument setup goes on the bench.
This checker parses a rack or bench instrument list, validates each address against the allowed range, and flags duplicate addresses before the setup hits the bus.
It is built for older rack-and-stack systems, field benches, and mixed fleets where GPIB is still part of the daily workflow.
The math and how it's used
Use this to sanity-check a GPIB address plan before a rack build or bench integration session turns into needless troubleshooting.
It is intentionally practical: catch duplicate addresses, out-of-range values, and export a clean map so everyone on the system is working from the same assignment list.
What it does not do
This tool checks address planning only. It does not verify drivers, controller settings, cable integrity, bus timing, or remote-enable state.
If the address map is clean and the rack still misbehaves, the next step is usually manuals, driver support, or hardware service.
