103-0209-00
The Tektronix 103-0209-00 GPIB adapter is a standard accessory that came with the DF2.
It is a cable with a standard 24-pin GPIB connector on one end, and two pairs of standard P64xx input leads on the other that were intended to be connected to two P6451 probes, one for control signals, the second for data lines.
It connects GPIB DIO1..DIO8 to CH8..CH15, DAV to the CLOCK input, ATN to CH7, EOI to CH6, SRQ to CH5, and REN to CH4.
GPIB signals DAV, NRFD, NDAC and IFC are brought out to pins on the connector. CH3..0 are user defined inputs that can track any of these signals, or others as needed.
