Keysight M8131A 16/32 GSa/s Digitizer User's Guide
This example program (Capture.sln) demonstrates how to set up the
M8131A digitizer for capturing a test signal.
In the example, channel 1 of the digitizer is used. Data acquisition is done
in direct mode with decimation factor 4. The program works with 16GSa/s
and 32GSa/s ADC sample rate. The sample rate must be set before
starting the program.
•
Analog input channel 1 - receives the test signal to be digitized
Before starting the example program, start the M8131A and prepare the
signal source to capture. If needed, change the sample rate in the
M8131A.
The program uses "TCPIP0::localhost::hislip0::INSTR" to access the
M8131A, and it assumes that an analog signal is connected to channel 1.
It can be started with command line parameters to use other VISA
resource strings for M8131A and another input channel.
Command line: Capture digitizer-resource channel
Example call: Capture "TCPIP0::localhost::hislip2::INSTR" 2
In each step after each SCPI command is sent to the digitizer, the
execution status is read, and errors displayed.
1
Set the digitizer to Direct mode.
2
Set the trigger level on the input channel.
3
Set trigger source to the input channel.
4
Set sweep mode to Triggered.
5
Set the number of samples to capture.
6
Set up capture on the digitizer.
7
Set the decimation factor.
8
Start capturing data.
9
Wait until the acquisition is completed.
10 Set binary data upload format to big-endian.
