Specifications
Version
04.00
May
2007
Specifications apply under the following conditions: 30 minutes warm-up time at ambient temperature, specified environmental
conditions met, calibration cycle adhered to, and all internal adjustments performed. Data designated "overrange" or "underrange" and
data without tolerance limits is not binding.
EMC specifications are tested with sufficiently shielded cables and accessories (e.g. mouse and keypad). To prevent degradation of
these specifications, the user is responsible for using appropriate equipment.
In compliance with the 3GPP standard, chip rates are specified in Mcps (million chips per second), whereas bit rates and symbol rates
are specified in kbps (thousand bits per second) or ksps (thousand symbol per second). Mcps, kbps, and ksps are not SI units.

Triggering
In internal clock mode, a trigger event
restarts the clock generation. The clock
phase is then synchronous with the trigger
(with a certain timing uncertainty).
In external clock mode the trigger event is
synchronized to the symbol clock.
