The Model 2891-IQ Upconverter enables complete testing of a transceiver by processing analog I and Q baseband signals for the transmitter and processing analog I and Q output signals from the receiver. The Model 2891-IQ takes single-ended baseband, analog I and Q signals from a signal generator and converts the signals to differential output signals to provide a signal for transmitter testing. On the receiver side, the Model 2891-IQ converts the down converted differential I and Q signals into a modulated, up converted signal for receiver performance testing by an RF signal analyzer. |
