用的是dell 700m，前两天好像有病毒，老是一些不明的对话框弹出，
今天一下子就蓝屏了，重启后蓝屏显示了一些error的代码，
按照网上搜的提示，按着Fn启动电脑，进行诊断，发现有以下两个
错误信息：
DST short status test
Unit 4:Drive Self Fail 1000-0142
Test failed status byte=79
Error code: 0F00:136C
Msg: IDE device failed: Blank m,edia or no media is present
in optical drive.
Test requires media with digital data(Resoource Cd,
installation CD)
请告诉一下应该怎么办。。。多谢！！！

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

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.

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?

肯定是有的,关键是这样的仪器你有没有.现在很多数字示波器都能把数据存下来.

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.

You can download the sample program from Agilent.

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!
