E. Configure Board Menu
This command accesses a menu called the BOARD,
INTERFACE MENU. The BOARD, INTERFACE MENU is
used to select among several board configure command
options, including configure channel 1, configure channel 2,
configure channel 3, configure channel 4, or configure all
modulator channels.
D. Test Menu
This command accesses a menu called the TEST MENU.
The TEST MENU is used to select among several “run”
options, including reset the board, write to a location while
reset, read to a location while reset, write to a location while
running, or read from a location while running.
For a detailed listing of every Menu screen, with selection
item definitions, refer to Appendix G - Descriptive File List.
Configuration/Test Headers
Fifteen dual row test headers located on the evaluation circuit
board are used to monitor signals and set control pins. The
pin assignments for each of these headers are found in
Appendix D - Test Header Pin Assignments.
Typical Evaluation Configuration
Figure 2 identifies the configuration of a typical performance
evaluation setup. A test PRBS data pattern is created via a
stimulus file and used by a modulator to generate a
modulated IF signal. Noise and other signal impairment
stimulus files can be used with additional channels to create
a cascaded/summed composite IF signal that is routed to a
D/A converter (DAC), generating an output analog signal.
The digitized IF signal is also routed out of the circuit board
allowing multiple boards to be cascaded together. To check
out a complete communication systems, the modulator
output can be routed to a demodulator, whose baseband
output is connected to a Bit Error Rate Tester (BERT) for
measuring the Bit Error Rate (BER) performance.
Getting Started
Evaluation Circuit Board Configuration and Set Up
1. ___ Power down the host PC and remove the cover to al-
low access to the motherboard empty slots.
2. ___ Review the jumper configuration of the
HSP50215EVAL Board to verify that the jumpers are
properly set for the configuration desired. Appendices
B (especially the jumper diagram at the end of the ap-
pendix), D and E will be helpful in this verification.
3. ___ Install the HSP50215EVAL into one of the empty ISA
slots on the host PC motherboard. Make sure that a
good connection is made with the motherboard and
that the connectors fit in the slots in the rear of the PC
chassis properly. Record the oscillator frequency for
future reference: ____ ____ ____Hz
4. ___ Re-install the PC chassis cover and power up the
computer.
The circuit board is ready for use.
Requirements for the Control Software Program
In order to properly operate the HSP50215EVAL Control
Software Program included in the evaluation kit, the PC must
meet the following requirements:
PC/XT/AT or 100% compatible with a minimum of 640K of
RAM
DOS Version 3.0 or higher.
One parallel port with 25 pin connector.
Installing the Software
The instructions that follow will load both the
HSP50215EVAL software onto the “C” drive of the computer.
If you do not wish to run the software from the “C” drive,
consult your computer user’s manual for operation from
another drive. It is “good practice” to backup original disks
prior to installing the software on your computer.
1. ___ Insert the HSP50215EVAL distribution disk in Drive A
and copy the contents of the distribution diskette to the
target directory on Drive C. Note: This must be done in such
a way as to retain the file structure of the distribution disk.
