   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. 

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: 

  

 

 

 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.  

  

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: 

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

Enter 

 to indicate a floating-point file. 

Next you will be asked for the filename: 

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:
