PHY Timing

You must manually set the correct delay values for the PHY on the probed MPI. You can
typically find these values on the PHY datasheet:

SyncDelay (ns): Delay from the end of the last symbol of the Frame Synchroniza-
tion Sequence of the preamble waveform in the local antenna to the time when the
PHY asserts PHY_ACTIVE, in nanoseconds.

PhyActiveDelay (ns): Delay from the end of the last symbol of the frame received
in the local antenna and PHY_ACTIVE de-assertion, in nanoseconds.

Note: For RF, you do not need to set the PHY Timing parameters because the

software knows these values for the UWBTracer/Trainer PHY module.

Encrypted/Decrypted Recording

You can show secured decrypted traffic, original (secured or not secured) traffic only, or
both types of traffic:

Decrypted (Secured) + Non-Secured Traffic Only: Records all non-secure
frames; records secure frames, and stores decrypted payload.

Original (Secured or Non-Secured) Traffic only: Records all non-secure and
secure frames unchanged.

Both: Interleaves Decrypted and Original Traffic.

For information about setting decryption connection contexts and temporal keys, see
Section 9.7, “Device List” on page 131.

(For information about encryption keys, association data, and 4-way handshakes, see
Section 11.5, “Secured Traffic” on page 171.)
