content: Hi,i've tried to install the latest XStream Software (7.9.0.1) on a fresh Windows XP installation. However, that doesn't seem to work. There are no drivers installed for the XStream PCI device. Does anyone know what the latest supported version on the WavePro 7300a is?Thanks

content: Quote from: dxl on May 04, 2016, 09:02:00 amThe latest supported version is 7.9.0.1, the download for the WP7kA can be found here:http://teledynelecroy.com/support/softwaredownload/documents.aspx?sc=11Make sure that the DSO drivers are selected for installation.Also, make sure to update XP to SP2 or later (ideally SP3) before installing the software.

content: I tried that, but it seems like the 7.9 doesn't provide the DSO driver for the so called 'Aladdin' Acquistion. In the drivers folder only 'Magelan' drivers are present. I've tried the 6.8 Version, and that worked. Maybe i'll try to install 7.9 now that 6.8 is installed, maybe that way works. Still have to figure out how lecroy finds their calibration data as i copied the whole userdata partition from the old harddisk.

content: Installing Xstream 7.9 after 6.8 worked. Just need to get the calibration data back in place and install minor stuff like chipset + touchscreen driver

I've done a few fresh installs (although none with 7.9) and it was pretty much just installing Windows with updates and graphics/network drivers, and then installing the latest X-Stream version.Strange.

content: I don't know why the touchscreen driver wasn't installed automatically. I've reinstalled everything today, still the same. Installed the touchscreen driver later manually, and everything is fine now. Also got the calibration data back in place.Most annoying thing right now is that everytime you change horizontal time/div in large steps (like from 1ms to 100ns), it recalibrates which takes about 10s. I already disabled the temperature auto calibration, but that didn't change anything. Any hints?Thanks

content: Quote from: dxl on May 07, 2016, 08:06:05 pmAside from the fact that it's changes to the vertical scale which triggers the recalibration cycle, that's normal. All LeCroy high-end scopes do this if a vertical change results in changes to the signal path (which contains RF relays) to make sure the path and ADC remain within specs.In addition, the scope does a recalibration when the internal temperature changes to a certain extend. There's a setting to disable that so that a critical measurement is not interrupted, but that will be reset during the next power-up. I would leave it on, as thermal recalibrations will only occur during the warm-up phase (10-15min) and, provided your room temperature doesn't change' will pretty much disappear.This is different from other scope manufacturers' scopes which only self-calibrate quickly at power-up and don't compensate for temperature shift or multiple vertical settings, and where a more thorough calibration has to be started manually.The time for the calibration variies depending on what WavePro you have. The older non-A variants took the longest to recalibrate, the 'A' models reduced the time for the calibration at vertical changes, and the later models (i.e. manufactured at end of 2007) have noticably reduced calibration cycles (ie. 2 - 3 seconds).

content: I confirm this... just installed 8.x on a blank XP SP3 for a WaveSurfer XS-A, and the drivers for the interface & acquisition boards are NOT included... (or at least the installation scripts for those are not triggered...), I needed to install something prior to 7.9.x...Didn't re-upgrade so far, but I assume this will be OK...

content: Beating a dead horse but I have also observed the same with my WR6050. Firmware 6.5.0.5 appears to have the drivers but 8.1.0.1 does not.
