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 . 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"", #"
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.
