4.6.2 Timing Calculations
This menu item (enabled only for files recorded with Idle state) opens the following “calculator”
display, permitting computation of the time difference between any two packets in the file:
Entering relevant packet numbers and selecting the “Calculate” button results in a display of the
packet-to-packet time (measured from start of Sync to start of Sync) in both microseconds (or
milliseconds), and bit times. If no packet numbers are entered, the computation is performed over
the entire range of packets in the currently displayed file. An appropriate error message is
provided if either of the selected packets does not contain a Sync field (i.e., SUSPEND or
RESET sequences).
If additional check boxes are marked, further information will be calculated and displayed (note
that bus usage computation can take a noticeable amount of time, depending on the range of
packets selected). Usage will also be computed for specific addresses (and optionally, endpoints;
if ENDP is left blank, all endpoints for the specified address will be included).
