发帖数: 737 | 1 I'm designing a measurement, which need record many consecutive signals for
later processing.
My pulser-receiver works at 2KHz recurrence frequency (500 micro second
interval). I want to record the first 100 micro seconds of received signal
for 200 consecutive echoes. Each of them stored separately.
Anybody know what kind of instrument can do it? I hvae a LeCroy WaveSurfer
42Xs digital oscilloscope. Never know it has capability to do such job.
Thanks |

发帖数: 858 | 2 You can read the data over GPIB port. Just buy an GPIB card and write a
program in C to communicate the oscilloscope.
I use the Agilent oscilloscope. |

发帖数: 737 | 5 I know very little about GPIB communication. Does the program write the
received signals to HDD files or just stored in memory variables? Do you
have a sample program to share with me? Thanks!
Which model of Agilent are you using?

发帖数: 858 | 8 Read the datasheet or the programming guide of your oscilloscope. I use the
Agilient 54622D mixed signal oscilloscope. The latest model would be more
powerful.
The GPIB protocol is pretty simple. You might purchase a GPIB card with USB
port connection. Then install the driver and invoke visa functions.
The received data can be read by the GPIB port and stored wherever you want.
You can get more information from agilent website.

发帖数: 737 | 10 Thank you. Just talk with LeCroy supoort. The scope has autosave function,
which will store the signal into file each time it is triggered. Exactly
what I want. I have been thinking about this function for almost 2 years and
this scope was bought about 6 months ago. Just never know it can work so
far. Shame for me!
