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.

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 generated 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.

Amplitude is settled within 0.5 dB in 20 µsecs, +4 to –136 dBm at 23 ± 5 °C

Modulation

π/8-rotating 8PSK (per EDGE specifications) user-selectable (see

Filter

Option UN8) 270.833 kHz (default)

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.
