The Gould/Biomation Model K450B
is a precision, high-performance test and development
instrument. The K450B
monitors and records digital input
logic signals generated by the user’s external target
system. The K450B
provides 80 input channels at 100MHz, 40
input channels at 200MHz, and 20 input channels at400MHz.
The 400MHz capability requires the use of an optional 400MHz
described in Appendix C. The optional 100 MHz State
is described in Appendix E.
provides 10 ns resolution at 100 MHz, 5 ns
resolution at 200 MHz, and 2.5 ns resolution at 400MHz. The
also provides sophisticated trigger schemes, a
versaiiie ciock scheme, and a variety of data options. The
user can rapidly examine and record addresses, data and
control signals of ECL based systems, gate arrays, bit-slice
processors and other high-speed microprocessors.
control logic performs measurements on the input
signals to correlate data/timing characteristics, accomplish
comparisons, and capture data samples; the results are then
recorded in memory. The measurement operations are
screen-driven by resident firmware which is controlled by
manipulating various keys on the Keyboard Panel. The screens
allow the user to set up test conditions, capture the
results of binary logic states via trace control for
data-domain analysis and display pulse-train waveforms for
time-domain analysis. The display screen presents the
results of analysis for examination or modification by the user.
The user-friendly control firmware generates the screens for
selecting acquisition parameters and allows direct control
over the acquisition process; furthermore, the control
firmware displays and interprets the acquired data, and
informs the user of current system status. Because the
control firmware of the K450B
is simple to use and
versatile, the instrument is suitable for a variety of uses
including laboratory Software
and hardware development, test
engineering, and field-services testing.
offers the user a screen-guided Trace Control*
that is simple to use, and powerful. Trace levels can be
rapidly set up using either the Auto Setup* feature or
display menus and front panel keys. The flexibility of Trace
Control is enhanced by a selection of commands that allow
the user to select information to record.
Data may be displayed in hexadecimal, octal, binary, ASCII,
and EBCDIC format, or a user specified format.
The Auto Setup* feature identifies all active inputs and
configures the Logic Analyzer
to record and display circuit
activity. Pressing the SHIFT key then the CLOCK key executes
the Auto Setup, reducing setup time and simplifying operation.
to the user's system via rear panel
connectors that provide IEEE-488 (GPIB)or RS-232-C
communication linkages. The I/O Setup Screen allows the user
to set up parameters and initiate transfer operations.
The GPIB Interface
allows parallel transfer to setups and
data between the K450B
and the user's system. The
communications parameters are programmable by the user to
set up the following communication modes for the GPIB link.
Talk Only Mode Listen Only Mode Talk and Listen Mode
Transmit data and commands to a user's system.
Receive data and commands from a user's system.
Perform interactive two-way dialogue between the K450B
The RS-232-C Interface
allows serial transfer of setups and
data between the K450B
and a user's device, such as printer,
personal computer, or terminal. The I/O Setup Screen allows
the user to specify conditions, such as baud rate, protocol,
or word length, that are used to control the I/O communication.
