This page provides answers on some of the more common questions regarding our DisplayPort Analysis Probes.

Q. What is DisplayPort?

A. DisplayPort is a digital display interface standard (approved May 2006, current version 1.1a approved on Jan 11, 2008) put forth by the Video Electronics Standards Association (VESA). It defines a new license-free, royalty-free, state-of-the-art digital audio/video interconnect, intended to be used primarily between a computer and it's display monitor, or a computer and a home-theater system.

Q. What software is included with the FS4430 DisplayPort Analysis Probe?

A. Files are included that automatically set up the Agilent logic analyzer for protocol disassembly mode and label all the signal names. Another file contains two protocol disassemblers, which translate the data into DisplayPort protocol during state analysis. One dissambler decodes the Main Link and the other decodes the Auxiliary Channel. Finally, the Probe Manager software is included. This allows you to change and store the probe configuration, pixel recognizer and filter settings in the FS4430 via a USB interface.

Q. What is the difference between the FS4430 and FS4432?

A. The FS4430 includes the capability of simultaneously analyzing traffic on both the Main Link and Aux Channel. The FS4432 only includes the capability of analyzing the Aux Channel, and is thus more economical. The FS4432 can be upgraded to the FS4430; contact FuturePlus for details.

Q. What target cable adapters does the FS4430 include to connect to my target system?

A. Because there are several different ways that customers may need to connect to their Main Link, we do not include any target cable adapters with the FS4430. You must choose at least one target cable adapter with your FS4430 order. Click here to see the various target cable adapters available. Auxiliary Channel and HPD cables are included with the FS4430 and connect to user-supplied stake pins on the target.

Q. Does your analysis probe get its power from my system?

A. No. All necessary power is supplied by an external supply (provided).

Q. How much LA memory is need to capture one frame of data?

A. Here's a simple trace depth calculation for 1 frame @ 60 Hz refresh rate (frame rate is 16.6667ms).  At 2.7 GTs and each symbol 10 bits, you get (16.6667ms) X (2.7e9) / 10 = 4.5M states.

Q. What do the LED's on the FS4430 signify?

A. These are Quad-state LEDs. Green indicates the link is OK. Orange indicates invalid or unaligned data. Red indicates a receiver fault. Dark indicates a loss of signal.
