The received data is stored in the following folder:
ADPROOT/examples_perseus6010/perseus6010_adac250_record_playback/bin/record_data.bin.
To visualize the received data using Matlab, proceed to step 17.

Playback Test Result
The following window shows a successful PicoDigitizer250 playback test. Select the continuous playback option for the
playback module to continuously output the generated sine signal loaded in memory. When the playback has started, the
oscilloscope should display a sine wave at 977 kHz.

Plotting Recorded Data using Matlab
In Matlab, change the current folder to
ADPROOT\examples_perseus6010\ perseus6010_adac250_record_playback\bin.
Run this command: bintofft(‘filename’, num_of_channels_to_plot, 'int16', number_of_samples, acquisition_frequency);
For example:
bintofft(
'
record.bin
'
, 2,
'int16'
, 1024, 250000000);
Matlab will plot the received data and the FFT for each channel.
In the figures above, we clearly see the 10MHz tone in the time spectrum plot and the frequency spectrum FFT plot.
