This page provides answers on some of the more common questions we receive regarding our AGP3.0 Analysis probes. For answers to questions on our FS2220 AGP 2X and FS2221 AGP 4X analysis probes, click here.

Q. What is the difference between your three AGP analysis probes, the FS2220, the FS2221, and the FS2229?

A. The FS2220 is for timing analysis only. It supports AGP speeds of 66 MHz (1X) and 133 MHZ (2X). The FS2221 is for state analysis only. It supports AGP speeds of 133 MHz (2X) and 266 MHz (4X). The FS2229 is also for state analysis only. It supports AGP speeds of 532 MHz (8X).

Q. Does the FS2229 also support AGP 4X?

A. No.

Q. Why do I need the FS2229 to probe an AGP3.0? Isn't the 16753A-756A family of cards fast enough to probe it directly?

A. The AGP3.0 transfers data at 533 MT/s ; the minimum data valid window required by a probe is 400 ps. The 16753A-16756A family minimum data valid window is 800 ps. The FS2229 can acquire the data correctly with a 400 ps data valid window. It also samples the data on both the rising and falling edges, in effect slowing it down so it meets the input requirements of the logic analyzer module you are using.
