echo off cls echo. echo. echo Hewlett-Packard Applications Computer Aided Design program (AppCAD) is echo a collection of software tools (or modules) which aid in the design of echo RF and Microwave circuits and systems. AppCAD also includes a part echo selection guide for Hewlett-Packard RF and Microwave semiconductors. echo. echo The following modules are included in the program: echo. echo Transistor Design Data echo Mixer Spurious Search echo Microwave Calculator echo Microwave Path Calculations echo Transmission Lines echo Two-port Circuit Analysis echo Spiral Inductor Design echo Impedance Matching echo PIN Attenuator and Switch Design echo Schottky Detector Calculations echo Transistor Bias Circuits echo NoiseCalc echo. pause cls echo. echo. echo Module list continued: echo. echo Thermal Analysis echo Product Selection Guide echo Literature Request echo Sample Request echo Register for Updates echo For More Information echo. echo HARDWARE REQUIREMENTS echo --------------------- echo. echo AppCAD is designed to work on all Hewlett-Packard Vectras or IBM PC/XT/AT echo and compatible computers. A hard disk MUST be used to install and run the echo program . MS-DOS(R) versions 2.0 or higher should be used. The recommended echo minimum memory size is 512 Kbytes. All printed outputs are directed to echo parallel port LPT1. Printing graphic screens require an Epson compatible echo printer. echo. echo. pause cls echo. echo. echo COPYING AND DISTRIBUTION echo ------------------------ echo. echo AppCAD may be copied and distributed freely as long as no fee echo is charged. All AppCAD files must be included and not modified. echo Hewlett-Packard Co., 1990.

On your hard disk create a directory AppCAD using the DOS MKDIR echo command . Also, create a sub-directory AppCAD\SPARA. echo. echo 2. Copy from Disk 1 the files README.BAT and PKUNZIP.EXE into the AppCAD echo directory using the DOS copy command. From the AppCAD directory type: echo. echo PKUNZIP A:\APPCAD1.ZIP C:\APPCAD echo. echo Wait until PKUNZIP is finished then insert disk 2 into drive A and type: echo. echo PKUNZIP A:\APPCAD2.ZIP C:\APPCAD echo. echo Wait until PKUNZIP is finished then insert disk 3 into drive A and type: echo. echo PKUNZIP A:\SPARA.ZIP C:\APPCAD\SPARA after PKUNZIP is finished AppCAD echo is installed. echo. echo. pause cls echo. echo. echo STARTING THE PROGRAM echo --------------------- echo Type AppCAD echo. echo This assumes you are already in the AppCAD directory. echo. echo. echo Vectra users can run AppCAD from PAM with the following setup: echo. echo Path: C:\AppCAD (Drive C is for this example. Use the drive you echo loaded AppCAD onto.) echo. echo Applic Title: AppCAD echo. echo Run Command: AppCAD echo. echo. pause cls echo. echo. echo PROGRAM STATUS AND ERROR MESSAGES echo ---------------------------------- echo. echo Watch for messages on the bottom of the screen (the 25th text echo line). These messages can help guide you through the program echo by indicating what data the program expects or which keys are echo active. Error messages such as : " Value out of range " may appear echo after a calculation. This indicates that a calculated value is echo too large to display properly in its designated output field, and echo is an error with displaying the number not a calculation error. echo. echo Memory resident programs such as DOS shells, and pop-up calendars echo or spreadsheets may leave too little room for AppCAD to load or echo function. An error message "program is too big to fit in memory" echo may indicate such a problem . In this case, run AppCAD without echo the resident program(s) installed. echo. pause cls echo. echo. echo HELP SCREENS echo ------------ echo On line help screens are available and should be read before using a echo program module. The help screens contain useful information on each echo of the program modules. echo. pause cls echo S-Parameters echo ------------ echo S-parameters for Hewlett-Packard's RF and Microwave transistors and echo monolithic amplifiers are included with AppCAD. These files are echo are in Touchstone text file format and are located in the subdirectory echo X:\AppCAD\SPARA (X is the drive selected by the user when AppCAD is echo installed). The s-parameter files can be accessed from both the echo Transistor Design Data and Two-Port Circuit Analysis modules. Refer echo to the help screens of these two modules for further details. echo. echo The s-parameter files are also located on disk 3 in a non-compressed echo form . echo. echo Some transistor file names are slightly different than their actual echo part number. As an example: echo. echo XTR3615B.S2P corresponds to HXTR3615 and echo SMX3131A.S2P corresponds to HSMX3131. echo. echo This was done to conform to DOS's limit of eight characters for the echo filename. The letter subscripts are used to denote different bias echo conditions. echo. echo. pause cls echo. echo MS-DOS is a U.S. registered trademark of Microsoft Corporation. echo.
