Maximum Transfer Rates:
Data Settling Time:
HP·IB Address:
Medium/Slow-Speed:
High-Speed:
500 kbytes/second
980 kbytes/second
(Note: transfer rates are host-computer and software dependent)
Medium/Slow-Speed Operation: May exceed 500 ns (e.g. 2 pS)
High-Speed Operation:
350 ns minimum
Switch-selectable (set to 30 decimal when acting as the Controller-in-Charge of
the HP-IB).
HP·IB Signal Line Terminations:
Without the optional load resistor pack installed (the card configured for
medium/slow-speed operation), each of the 16 HP-IB signal lines is terminated
with a 2.3K ohm resistor to Vcc and a 4.7K ohm resist.or to common. With the
installation of the load resistor pack for high-speed operat.ion, signal line
termination values are changed except for the REN line, which is not affected.
Hp·IB Signal Line Drivers:
1-2
Each of the 16 HP-IB signal lines is driven with a circuit having the following
typical characteristics:
Type:
Output Voltage, Low State:
Output Voltage, High State:
Tri-state, open collector
< 0.5 V, 48 mA
> 2.5 V, -5.2 rnA
