“…The TCA is compatible with transmitter systems that use frequency diversity, complex modulations, phase coding, and multiple PRFs; Figure 2 shows the TCA measuring a high power amplifier (HPA) in‐system. Samples of the HPA's input and output RF signals are coupled off and routed to the 2–18 GHz dual‐channel receiver (Mitsdarffer et al 2005). The dual‐channel receiver uses a patented (Mitsdarffer et al 2006) technique to convert frequency‐agile RF signals to a fixed IF frequency without a tunable local oscillator.…”

The development of a 2-18 GHz instrument for radar and electronic warfare (EW) transmitter test and measurement is reported. The transmitter component analyzer was developed by NSWC Crane to measure critical performance parameters of the AN/SPY-1 radar's components. Typical measurements include clutter attenuation, clutter improvement factor, intrapulse noise, moving target indicator residues, random pulse jitter, systematic pulse jitter, phase noise, and amplitude noise.
