Get #FileHandle, index + 1, data '(index+1) is the record number
iq_data(index) = data
Next index
Close #FileHandle 'Close the file
'Write the command to the Header string. NOTE: syntax
Header = "MEM:DATA ""/USER/WAVEFORM/IQ_DataVB"","
'Now write the data to the signal generator's non-volatile memory (NVWFM)
SigGen.WriteIEEEBlock Header, iq_data

Creating and Downloading Waveform Data Using HP BASIC for Windows®
On the documentation CD, this programming example’s name is “hpbasicWin.txt.”
The following program will download a waveform using HP Basic for Windows into volatile ARB
memory. The waveform generated by this program is the same as the default SINE_TEST_WFM
waveform file available in the signal generator’s waveform memory. This code is similar to the code
shown for BASIC for UNIX but there is a formatting difference in line 130 and line 140.
To download into non-volatile memory, replace line 190 with:
190 OUTPUT @PSG USING "#,K";":MMEM:DATA ""NVWFM:testfile"", #"
