UXA — N9041B
This test measures the Total Amplitude Accuracy of RF Input 2 from 75 GHz to 110 GHz. A source extender is used to multiply the frequency of the PSG-D signal generator by six. The E8257DV10 source extender typically outputs approximately +10 dBm over the frequency range. A 20 dB fixed waveguide attenuator is connected to the source extender output so that the DUT input power will be approximately –10 dBm. A power meter is used to characterize the source extender output power at various test frequencies. The source extender is then connected to the DUT and the power is measured at the same test frequencies. The Total Amplitude Accuracy (in dB) is the amplitude difference between the power meter reading and the DUT reading.
The picture below shows the gold-colored waveguide adapter attached to the fixed attenuator which is attached to the output port of the source frequency extender.
The cable from the power sensor will attach to the adapter on the fixed attenuator. It is recommended that the power sensor and cable be kept level with the attenuator using an appropriate support (e.g. foam pad) as shown in the picture below.
