Set oscilloscope trigger back to auto

[Qlong]

Hi,

I am running Labview 8.2.1 to control Wavesurfer 64xs oscilloscope viaTCP/IP. The drivers are downloaded from NI http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=14665.

The oscilloscope acquires signals in bursts, and I need to use average (~10) to reduce the noise. The signals are controlled to change immediately after the previous data being read and stored. But the program "Read Signle Waveform.vi" can only wait 1 single trigger and stop, which I found is beacuse the subprogram "Initiate.vi" will write the buffer code "*CLS;ARM;" to the oscilloscope. So I am not be able to do averaging on the oscilloscope now.

I am wondering how can I set it back to auto trigger aftering reading the waveform, or alternative methods to realize averaging.

Thanks so much...

I believe the command you want is

TRG_MODE AUTO

Acording to the Lecroy Remote control manual the trigger mode is set this way.

The TRIG_MODE command specifies the trigger mode

The TRIG_MODE? query returns the current trigger mode

Command Syntax TRIG_MODE <mode>

<mode> = {AUTO, NORM, SINGLE, STOP}

Hi Qlong,

Alan from LeCroy Tech Support here... The driver has a function for this: "Configure Continuous Acquisition".  This VI allows you to configure the STOP, AUTO and NORM trigger modes.  Use Initiate for single triggering.

Dear Alan and Qlong,

I am using a lecroy Waveform 64XS oscilloscope, but scope starts to give an error in windows.

I need to re install xp embedded, but i have no xp image for this scope.

Would you help me how to install xp embedded or give me the image of software from your scopes.

I can download image from rapidshare or other upload sites.

Please help, thanks

Hi spear,

The scope has a hidden partition with a recovery image.  See the Getting Started manual for info on performing a system recovery: http://www.lecroy.com/tm/library/manuals/WSXS/GettingStarted/WSXS-GS_RevC.pdf

Best Regards,

Alan

Dear Alanjb, Thanks for quick reply in forums.ni about recovery of 64xs.We tried to apply the recovery steps in the datasheet, but we didn’t enter the recovery part of the scope by using F4.How can you help us?  Do you have any suggestion? Thanks a lot.
