Creating and Downloading Waveform Files

Programming Examples

As discussed at the beginning of this section, I and Q waveform data is interleaved into one file in

2’s compliment form and a marker file is associated with this I/Q waveform file.

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 "BASIC_Win_file"

20 Num_points=200

30 ALLOCATE INTEGER Int_array(1:Num_points*2)

40 DEG

50 FOR I=1 TO Num_points*2 STEP 2

60 Int_array(I)=INT(32767*(SIN(I*360/Num_points)))

70 NEXT I

80 FOR I=2 TO Num_points*2 STEP 2

90 Int_array(I)=INT(32767*(COS(I*360/Num_points)))

100 NEXT I

110 PRINT "Data Generated"

120 Nbytes=4*Num_points

130 ASSIGN @PSG TO 719

140 ASSIGN @PSGb TO 719;FORMAT MSB FIRST

150 Nbytes$=VAL$(Nbytes)

160 Ndigits=LEN(Nbytes$)

170 Ndigits$=VAL$(Ndigits)

180 WAIT 1

190 OUTPUT @PSG USING "#,K";":MMEM:DATA ""WFM1:data_file"",#"

200 OUTPUT @PSG USING "#,K";Ndigits$

210 OUTPUT @PSG USING "#,K";Nbytes$

220 WAIT 1

230 OUTPUT @PSGb;Int_array(*)

240 OUTPUT @PSG;END

250 ASSIGN @PSG TO *

260 ASSIGN @PSGb TO *

270 PRINT

280 PRINT "*END*"

290 END
