Real-time EDGE 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 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.

Modulation 3π/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.

Improved ACP performance for TETRA, CDMA

and W-CDMA

(Option H99, ESG-D and ESG-DP series only)

ACP improvements for TETRA, CDMA and W-CDMA are

listed in the appropriate heading under Options 100, 101,

UN8, UN5, and H98 respectively. Specifications that are

changes from the standard are listed below.

Output power

250 kHz to 3 GHz + 10 dBm to –136 dBm

>3 GHz + 4 dBm to –136 dBm

Level accuracy Specifications degrade by 0.2 dB

Spectral purity

Nonharmonics >3 GHz specifications apply at

< +4 dBm output power

Amplitude modulation 500 kHz to 3 GHz specification is

typical

>3 GHz not specified

Pulse modulation

On/Off ratio

<250 MHz >60 dB

Level accuracy with digital modulation

<3 GHz specifications apply at <+7 dBm output power

>3 GHz specifications apply at <+4 dBm output power

Alternate time slot power level control

(Option UNA, ESG-DP and ESG-D series only)

Amplitude is settled within 0.5 dB in 20 µsecs, +4 to –136 dBm

at 23° C ±5° C
