7.1Quick Start Guide

This guide will show you how to download and generate SINE.FLT, an example waveform in floating point format. This file is on the supplied compact disk in the disc 4070A\arb\examples directory.

1. Connect a serial port on you PC to the serial port connector on the rear of the 4070A. You may temporarily detach your serial mouse if needed to free up a serial port. (Mouse operation will be restored after the download).

If your computer has a 9-pin connector, use a cable that is wired 1:1 or “straight through.” If you computer has a 25-pin serial port connector, install a 25 to 9-pin adapter (available at most computer stores) and then the 1:1 wired cable. If you wish to build your own cable, wire it as follows:

9 pin - 9-pin cable:

9 pin - 25 pin cable adapter:

2.Apply power to the 4070A. After a display of the hardware and software versions and serial number, the unit enters the Basic Sinewave mode of operation.

3.Run the program WAVELOAD.EXE. It could be found on enclosed compact disk. You may run this program on Windows 95/98/Me/NT4.0

START -RUN menu or from the DOS prompt.

The program will ask you which serial COM port the 4070A is attached to:

Please select a serial port:

1.COM1

2.COM2

3.COM3

4.COM4

Enter selection (1,2,3,4) >

After you enter a com port number, the program will next ask you for the type of data you are sending to the 4070A:

Please select a file type:

F Floating Point

T Time & Value Floating Point (.CSV, .PRN)

D Digital

H Hexadecimal

I Integer

B Binary

N Do not send a header

Enter selection: (F,H,I,B,N) >

Enter F to indicate a floating-point file.

Next you will be asked for the filename:

Enter filename (ESC to exit) >

Enter A:\ARB\EXAMPLES \SINE.FLT and hit the ENTER key.

NOTE: A quicker way to do the above is to enter all parameters on the command line. For example, if COM port is 2:

WAVELOAD /COM2 /F \arb\examples\sine.flt

For further details on how to use WAVELOAD.EXE, see the chapter 7.7

4.Press the ARBITRARY One Touch Mode Selection key to switch to Arbitrary Waveform mode. The 4070A will then generate the waveform at the selected clock rate and output level.
