Real-time EDGE 3 personality
(Option 202, ESG-DP and ESG-D series only)
Description
Option 202 is a firmware personality built upon the internal
real-time I/Q baseband generator (Option UN8). This option will
simulate both uplink and downlink EDGE signals. Data can be gen-
erated internally or externally with continuous data, or bursted and
framed signals. Use custom filtering and framing to keep pace
with the evolving definition of EDGE.
Modulation 3 π/8-rotating 8PSK (per EDGE
specifications) user-selectable (see
Modulation under Option UN8)
Filter “Linearized” Gaussian (per EDGE
specifications) user-selectable (see
Filter under Option UN8)
Symbol rate
User-adjustable (see Symbol rate under
Option UN8) 270.833 kHz (default)
Burst Shape Defaults to EDGE standard power vs.
time mask with user definable rise and
fall time. Alternatively, upload externally
defined burst shape waveforms.
Data structure Time slots may be configured as normal
or custom. The data field of a time slot
can accept a user file, PRBS (PN9 or
PN15), a fixed sequence or external
data. All other fields in a timeslot are
editable.

1. All specifications apply at 23 ± 5 °C.
2. With ALC OFF, specifications apply after the execution of power search.
With ALC ON, specifications apply for pulse repetition rates ≤ 10 kHz
and pulse widths ≥ 5 µs.
3. EDGE and IS-136HS traffic channels have the same physical layer. This EDGE signal
can be used to simulate an IS-136HS trafffic channel for component tests.
