PCIE-1X1 - One Lane Either Upstream or Downstream

When selected, PCIE-1X1 shows Lane 0. Now, select a Source for Lane 0's Upstream or Downstream packets.

Tip: Quickly change PCIEbus D protocols using the Protocol field on the Decode Setup dialog.

Now, use the right-hand dialog to set Initial Bit Rate, Level Type, Level in Percent (percent or absolute, based on

type selection), and Scrambling on (if no TS2) checkbox for your PCIEbus D lane information as desired.

 Initial Bit Rate - Adjust the initial bit rate value here to match the initial bit rate on the bus to which you

are connected.

LeCroy's PCIEbus Decode follows speed changes. It detects the request, and the subsequent Electrical Idle

Ordered Set (EIOS) triggers the speed change to the highest agreed upon supported rate. On the Setup

dialog for PCI Express decode, the user must enter the Initial Bit Rate, that is, the bit rate at the beginning

of the waveform.

Use the arrows to move through standard bit rates (2.5, 5, or 8 GT/s) and make a selection.

Touch the field twice (with a finger, or using a mouse) and provide a value using the slider bar, pop-up

keypad button (or keyboard), or the Default button.
