The Marconi 2026Q is designed to produce a fully calibrated combined RF output containing any mix of internally generated interference signals from its two RF sources, together with a calibrated signal path for a radio test set transmit output. A return path from the transceiver back to the radio test set receiver input is also provided through the instrument. This allows a CDMA receiver to be tested for sensitivity in the presence of single or dual tone interference. The interfering signals are combined without the need for any RF switching mechanism that would otherwise affect the test result.
Features:
Two tone interference generation for AMPS/CDMA receiver testing in accordance with IS-97-A/IS-98-A
Option for providing GSM signals for receiver and amplifier testing
Combiner output frequency range from 800 MHz to 2.0 GHz
Provides single calibrated point of reference for the transceiver under test
Excellent phase noise and spectral purity (low residual FM of typically 3 Hz and typical sideband noise of -121 dBc/Hz at 20 kHz offset from 1 GHz
