HP-IB Logic Levels
C AU T I O N
HP products delivered now are equipped with connectors having ISO
metric-threaded lock screws and stud mounts (ISO M3.5
×
0.6) that are
black in color. Earlier connectors may have lock screws and stud
mounts with English-threaded lock screws and stud mounts (6-32 UNC)
that have a shiny nickel finish.

It is recommended that you do not stack more than three connectors,
one on top of the other.
Hand-tighten the connector lock screws. Do not use a screwdriver.
A.8 HP-IB Logic Levels
The instruemnt’s HP-IB lines use standard TTL logic, as follows:
•
True = Low = digital ground or 0 Vdc to 0.4 Vdc
•
False = High = open or 2.5 Vdc to 5 Vdc
All HP-IB lines have LOW assertion states. High states are held at
3.0 Vdc by pull-ups within the instrument. When a line functions as
an input, it requires approximately 3.2 mA to pull it low through a
closure to digital ground. When a line functions as an output, it will
sink up to 48 mA in the low state and approximately 0.6 mA in the
high state.
N OT E
The HP-IB line screens are not isolated from ground.
