P77DESKEW Fixture Instructions

For P77STFLXA or P77STCABL tips, connect the tips to the

xture as

follows:

Locate the Port1 plastic clamp on the

xture and press down on the

spring-loaded clamp. Insert one of the probe tips in the direction shown in
the following

gure, and release the clamp so that the tip locks in place.

Figure 2: Connecting the probe tip to the deskew

xture

A green LED lights up under the probe tip clamp when the tip is properly
inserted.

Repeat the above step for inserting the second probe tip into the Port2
plastic clamp.

Verify that the green LEDs under both probe tips are on. If not,
double-check your connections.

For P77BRWSR browser accessory, there are several pads on the deskew

xture that can be contacted by the browser tips. Using these pads, two probes

with browser accessories or one probe with a solder tip and one probe with a
browser can be deskewed relative to one another.

The pads on the

xture provide access to the same signals routed to the

clamps used to connect the solder tips. There are also ground pads located in
the same area for use when deskewing using a single-ended signal.

NOTE.

The signals routed to the pads are delayed by 30 ps relative to the signal

output at the solder tip clamps. There is a 5.7 ps time difference between the

rst row of pads and the second row.
