Connections for a High Dynamic Range Swept IF Conversion Loss Measurement
14. To set the frequency offset mode LO frequency, press:
15. To select the converter type and low-side measurement configuration, press:
In this low-side down converter measurement, the analyzer’s source frequency range
be offset higher than the receiver frequency range. The source frequency range can be
determined from the following equation:
receiver frequency range (100 1000 MHz) + frequency (1500 MHz) 1.6-2.5
16. view the conversion loss in the best vertical resolution, press:
3-13 shows the conversion loss of this low-side mixer with output filtering.
Notice that the dynamic range from the pass baud to the noise floor is above the
dynamic range of the R Channel. If the mixer under test contained amplification,
then this dynamic range would have been even greater due to the conversion gain of the
mixer.
