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 20):
The medium of  claim 18 , wherein the instructions further configure the apparatus to:\n in the testing device reception mode and testing device transmission mode, bandpass filter the IF signal prior to and after amplification of the IF signal using bandpass filters having a same center frequency and bandwidth; and use a variable local oscillation (LO) signal that has a frequency dependent on the more than the first predetermined frequency to, in the testing device reception mode, upconvert the DUT signal to the IF signal and, in the testing device transmission mode, downconvert the IF signal to the testing device signal, such that an IF is maintained independent of the more than the first predetermined frequency, and use a fixed LO signal to, in the testing device reception mode, downconvert the IF signal to the signal of the first predetermined frequency and, in the testing device transmission mode, upconvert the signal of the first predetermined frequency to the IF signal.
