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 7):
The apparatus of  claim 1 , wherein:\n the signal of the first predetermined frequency is supplied to the second of the receiver and transmitter switches, each of the first and second double conversion circuitry comprises a pair of mixers and a pair of bandpass filters (BPFs) connected between the pair of mixers and an amplifier connected between the pair of BPFs, the pair of mixers in the first double conversion circuitry is configured to upconvert the signal of more than the first predetermined frequency to a second predetermined frequency and downconvert the signal of the second predetermined frequency to a third predetermined frequency, and the pair of mixers in the second double conversion circuitry is configured to upconvert the signal of the third first predetermined frequency to the second predetermined frequency and downconvert the signal of the second predetermined frequency to the more than the first predetermined frequency.
