10.1.9 Trace File Name & Path
Trace File Name & Path is the location for saving your trace file. The default recording
file name is data.usb for Low, Full, and High Speed recordings. If you are recording on
both channels, then the system creates two files: data_0.usb for Channel 0, and
data_1.usb for Channel 1.
• Click Trace File Name & Path.
Click Change Default Location to display a Save As… window in which to enter the
recording file name *.usb for all subsequent recordings.
Note : Due to restrictions on where files can be written by users in Windows™ Vista and
Windows 7, the USB Protocol Suite software may implicitly change a directory from the
Program Files path
x:\Program Files\Lecroy\…
to the user's data path
x:\Users\Public\Documents\Lecroy\…
This is done (for example) when the desired Trace File Name & Path has such a
reference in the Recording Options file. Note that when the opposite situation occurs (a
Windows Vista or Windows 7 path is referenced), no implicit directory changes are made,
since the Windows Vista/Windows 7 path is legal on an XP system. See “Notes on Vista
and Windows 7 Directory Protections” on page 68 for more information.
Important : Make sure that you do not attempt to save traces on a network drive on which
you do not have create or write permissions. Such an operation is not supported in the
current software.
10.1.10 Power
You can control power settings:
• Keep VBus Power on after Generation/Exerciser completes: Check if you want
to keep the Host VBus on at completion of a 2.0 or 3.0 Trainer/Exerciser script.
• Capture M3i Power Measurements (Voltage and Current): Record voltage and
current.
