2. How have Anritsu’s instruments and tools evolved in response to the needs of the defence and military sectors? Our products are specifi cally designed to enable defence teams to transition rapidly from simulation to testbed to systems in the fi eld. Ka-band mixer design and especially multichannel microwave downconverters are here to stay. For mixers used in radar or phased- array applications, it is very important to understand the magnitude and phase response of the frequency converter module, and whether this is linear or not under various circumstances (diff erent phase shiſt er settings, multiple LO paths of diff erent length, etc.). We off er various measurements with our VectorStar and ShockLine families of VNAs, and we are constantly working on innovating these instruments for off ering best-in class active device testing. Radar transmitter mandates the design

and verifi cation of high-power amplifi ers (HPAs) that should be thoroughly tested under pulsed RF conditions. For example, solid-state radars can detect targets at both long and short ranges, by transmitting a combination of long and short pulses. Having a VNA capable of modulating the sinusoidal signal with a train of diff erent pulse widths is of key importance for testing under realistic situations. Anritsu’s VectorStar VNA can generate various types of pulses thanks to the fl exibility of its PulseView soſt ware; see Figure 6. R&D engineers can then measure
the response of the HPA under this complex pulse stimulus with the best time resolution available in the industry (2.5ns) and the largest internal memory – up to 2.5s at full resolution; see Figure 7. We are constantly updating Anritsu’s

family of handheld VNAs and spectrum and signal analyzers, for matching the continuously evolving needs of the customer. T is means organising the product life-cycle of these instruments in a harmonised way, with major fi rmware releases planned every year with a selected schedule. Every new release incorporates key feedbacks received from our customers during sales visits, and
