MENU

14. ___ Repeat Steps 12 and 13 for MAIN MENU items (2),

(3), and (4). These submenus control Modulator

Channels 2 through 4. These submenus are identical

to those found under MAIN MENU (1) with the excep-

tion of the Channel Number and the names of the co-

efficient file, and stimulus file.

15. ___ Select MAIN MENU item (6) by typing 6 <Enter>.

This will save the edited configuration file. You are

prompted for a file name for your new configuration.

WARNING: Failure to change the .cfg file name may result in

overwriting of an example file with an edited version of that file.

16. ___ Select MAIN MENU item (7) by typing 7<Enter>. This

will compute the configuration register values and

generate the .1, .2, .3, and .4 files. (Filter and stimulus

files with .imp file extensions must be created prior to

running the HSP50215EVAL software - See Appen-

dix G - Descriptive File List) Note that MAIN MENU

items 1 through 7 can be executed without the evalu-

ation circuit board installed.

17. ___ Select MAIN MENU item (8) by typing 8 <Enter>. The

Board Interface Menu will appear as shown in Figure 7.

18. ___ If you have identified more than one channel for oper-

ation, selection of menu item (5) will load all the chan-

nels with one command. See step 25 for this action.

In testing, there are times when most of the channels

will remain the same and one channel or one channel

input will change. Menu items (1) through (4) are for

selective channel or channel input configuration. Se-

lect the menu item (1), CONFIGURE CHANNEL 1

MENU, of the BOARD INTERFACE MENU by typing

1<Enter>. A menu will appear with three execution

options, as shown in Figure 8. This is the same menu

that will appear when BOARD INTERFACE MENU

items (2) through (5) are selected.
