Teledyne LeCroy USB2-HSIC Decoder - Manual (Page 8)

USB2/USB2-HSIC Decode and Trigger
Setting Up the Decoder
The main Serial Decode dialog allows you to preset up-to-four, independent decoders, Decode 1 to Decode
4. Each decoder can use different (or the same) protocols and data sources, or have other variations, giving
you maximum flexibility to compare different signals or view the same signal from multiple perspectives.
TIP: After completing setup for one decoder using the procedure below, you can quickly start setup for the
other decoders by using the Decode # buttons at the left of the Decode Setup dialog. You don't have to step
back to the Serial Decode dialog to start the setup. Controls with the same label on either dialog share the
same function.
1. Touch the Front Panel Serial Decode button (if available on your oscilloscope), or choose Analysis >
Serial Decode from the oscilloscope menu bar to access the Serial Decode dialog.
2. On the same row as the Decode # (shown below):
l
Check On to enable the decoder now. This will let you view the decoding on screen as soon as
there is an acquisition, which helps to begin tuning. You can if you wish wait until all settings are
complete to enable the decoder.
l
Select the desired Protocol to use. The selections will depend on the software options installed on
your instrument.
l
Select the (Source) Data to be decoded. This can be any signal input channel (Cx), memory (Mx), or
math function (Fx).
l
For HSIC decoders, enter the Strobe source channel under Clock.
3. Optionally, check Link To Trigger On to tie the decoder setup to an additional serial trigger setup.
NOTE: This checkbox will only appear if the oscilloscope is equipped with an activated a TD or TDM
package and any required serial trigger hardware.
4. Touch the Setup button (next to Search) to open the Decode Setup dialog. If you use this method rather
than the tab, your settings will be correctly pre-selected on the Decode Setup dialog.
5. Go on to complete the required USB2/USB2-HSIC settings on the right-hand dialogs next to the Decode
Setup dialog.
