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 12):
A method for operating a testing apparatus, the method comprising:\n controlling, using a controller in the testing apparatus, a device under test (DUT) to transmit a signal; switching reception between a receiver bypass position used when the signal has at most a first predetermined frequency and a receiver direct position when the signal has more than the first predetermined frequency: double converting the signal of more than the first predetermined frequency by upconverting the signal to an intermediate frequency (IF) signal before downconverting the IF signal to a signal of the first predetermined frequency, bypassing double conversion of the signal when the signal has at most the first predetermined frequency; and supplying to an analog-to-digital converter (ADC) the signal of the first predetermined frequency or the signal of at most the first converted frequency, depending on whether the receiver bypass position or receiver direct position is being used, the signal from the ADC used to evaluate the DUT.
