Creating and Downloading E443xB Waveform Data Using HP Basic for UNIX

On the documentation CD, this programming example’s name is “e443xb_hpbasicUx2.txt.”

The following program shows you how to download waveforms using HP BASIC for UNIX. It is similar to the previous program example. The difference is the way the formatting for the most significant bit (MSB) on lines is handled.

First, the I waveform data is put into an array of integers called Iwfm_data and the Q waveform data is put into an array of integers called Qwfm_data. The variable Nbytes is set to equal the number of bytes in the I waveform data. This should be twice the number of integers in Iwfm_data, since an integer is represented 2 bytes. Input integers must be between 0 and 16383.

In the Output commands, USING “#,K” formats the data. The pound symbol (#) suppresses the automatic EOL (End of Line) output. This allows multiple output commands to be concatenated as if they were a single output. The “K” instructs HP BASIC to output the following numbers or strings in the default format.

10! RE-SAVE "ARB_IQ_file"

20Num_points=200

30ALLOCATE INTEGER Iwfm_data(1:Num_points),Qwfm_data(1:Num_points)

40DEG

50FOR I=1 TO Num_points

60 Iwfm_data(I)=INT(8191*(SIN(I*360/Num_points))+8192)

70Qwfm_data(I)=INT(8191*(COS(I*360/Num_points))+8192)

80NEXT I

90PRINT "Data Generated"

100Nbytes=2*Num_points

110ASSIGN @Esg TO 719;FORMAT ON

120ASSIGN @Esgb TO 719;FORMAT OFF
