The components that must be removed and replaced as a set because of factory calibration are the VM2164 2 channel TIC, 2 VM2601 14-bit digitizers, and the SMP1200-S-11267 attenuator. This means that all three of these components need to be replaced together in order to maintain the factory calibration of the advanced digital test station.

The signal required by the microwave signal conditioner (MSC) when making a biphase measurement are biphase modulaterd RF,
- LO1, LO2, and LRU 50 MHz REF
- LO1, LO2 and LRU 75 MHz REF
- AM REF, LO1 and LRU 50 MHz REF
- AM REF, LO1, and LRU 75 MHz REF
Correct Answer

A. LO1, LO2, and LRU 50 MHz REF

Explanation

The correct answer is LO1, LO2, and LRU 50 MHz REF. This is because the microwave signal conditioner (MSC) requires three signals for making a biphase measurement: LO1, LO2, and LRU 50 MHz REF. These signals are necessary for the modulation and referencing of the microwave signal to accurately measure the biphase modulation. The other options do not include all three required signals or include signals that are not necessary for biphase measurement.
