Abstract:
A test apparatus and method of testing a DUT are described. The apparatus includes a receiver and transmitter path each having a pair of switches that switch between a bypass position and a direct position. The bypass position is used for low frequency signals communicated through the apparatus. The direct position allows higher frequency signals to be double converted by upconversion to an IF signal and bandpass filtered before being downconverted to a predetermined frequency. Both variable and fixed LO signals are used to convert the double converted signals so that the same IF may be used independent of the higher frequency signal received or transmitted. Bandpass filtering is applied before and after amplification of the IF signal. Lowpass filtering before and after the double conversion use LPFs of different cutoff frequencies.

Claim (Index 2):
The apparatus of  claim 1 , wherein:\n the receiver path further comprises receiver front end amplification circuitry, an analog-to-digital converter (ADC) and first and second receiver lowpass filters (LPFs), the first receiver LPF connected between a first of the receiver pair of switches and the DUT, the second receiver LPF connected between a second of the receiver pair of switches and the ADC, the first of the receiver pair of switches more proximate than the second of the receiver pair of switches to the receiver front end amplification circuitry, and the transmitter path further comprises transmitter front end amplification circuitry, a digital-to-analog converter (DAC) and first and second transmitter LPFs, the first transmitter LPF connected between a first of the transmitter pair of switches and the DUT, the second transmitter LPF connected between a second of the transmitter pair of switches and the DAC, the first of the transmitter pair of switches more proximate than the transmitter of the receiver pair of switches to the transmitter front end amplification circuitry.
