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 18):
At least one machine-readable medium containing instructions for operating an apparatus of a testing device that configure the apparatus to:\n control a device under test (DUT) to transmit a DUT signal in a testing device reception mode and, in a testing device transmission mode, to receive a testing device signal from the testing device; switch reception between a receiver bypass mode when the DUT or testing device signal has at most a first predetermined frequency and a receiver direct mode when the DUT or testing device signal has more than the first predetermined frequency; double convert the DUT or testing device signal of more than the first predetermined frequency by:\n in the testing device reception mode, upconversion of the DUT signal to an intermediate frequency (IF) signal before downconversion of the IF signal to a signal of the first predetermined frequency; and \n in the testing device transmission mode, upconversion of the signal of the first predetermined frequency to the IF signal before downconversion of the IF signal to the testing device signal; and \n bypass double conversion of the DUT or testing device signal when the DUT or testing device signal has at most the first predetermined frequency.
