ESG Family Signal Generators Using Functions

Option 200 3GPP W-CDMA User Equipment Performance Tests

Required Equipment

The following equipment must be calibrated and must perform within the limits of its

published specifications.

• two ESG signal generators configured as a dual-output, two-ESG W-CDMA mobile test

solution

• E4406A VSA Series W-CDMA transmitter tester

• function generator (with an external frequency reference input) capable of providing an

external ESG data clock input with the following characteristics:

— wave type: square

— amplitude: 2.5 V

rms

— frequency: 3.84 MHz

— DC offset: +1.25 V

• 83712B synthesized CW generator (or another signal source capable of providing CW at

an amplitude range of

−

46 dBm to

−

15 dBm with an RF output frequency range of

2.11 GHz to 12.75 GHz)

• a UE test mode designed to allow the controller to assign the UE a dedicated physical

channel on which to receive and demodulate the transmitted data

• A system controller and software capable of providing control data to the UE

• software and/or hardware (a BER test platform) capable of measuring, calculating and

storing the UE’s bit error ratio (BER) while exposed to the test stimulus

• microwave frequency combiner

• BNC cables, tee splitters and adapters

• adapters and antennae as required by the UE

NOTE All ESG signal parameters are specified at the front panel RF OUTPUT

connector. Losses due to cabling and signal combining must be considered

when performing the tests.

1. The signal generator does not receive nor act upon uplink data from the UE.
