Description
The HP 1650B is an 80-channel STATE/TIMING (35 MHz/100 MHz) logic
analyzer, selectable in 16-channel groupings. The HP 1651B is a 32-channel
STATE/TIMING (25 MHz/100 MHz) analyzer, also selectable in 16-channel
groupings. The user interface for both models consists of a panel keyboard with an
RPG knob and a 9-inch, white-phosphor, high-resolution CRT for information
display. A 3.5-inch Sony disk drive, for setup storage and information retrieval, is
integral to the analyzers. An RS-232-C port, HP-IB port, and external arming
trigger are available on the rear panel. The RS-232-C and HP-IB ports are used
for printer hardcopy or for logic analyzer control via a controller. Either port can
be used for hardcopy or control.
The following items are other main features of the logic analyzers.
Simultaneous state/state, or simultaneous state/timing analysis.
Time interval; number of states; pattern search; minimum, maximum, and
average time interval statistics.
Transitional timing to store data only when there is a transition.
Clock qualifiers, storage qualification, time and number of state tagging, and
prestore.
Small lightweight, passive probing.
