How to Test Radar and Defense Systems with Narrow RF Pulses

Reproduce Controlled Narrow-Pulse RF Conditions

Pulsed RF testing requires a signal source configured for the carrier frequency, RF level, pulse width, and pulse repetition frequency (PRF) appropriate for the radar or electromagnetic spectrum operations (EMSO) subsystem. Pulse repetition interval is the time between corresponding points on successive pulses, while PRF is its reciprocal. Together with pulse width, these parameters establish the duty cycle of a repetitive pulse train.

Apply the pulsed RF stimulus to the component or subsystem and observe its response under the selected conditions. For repetitive pulses, duty cycle relates pulse width to pulse repetition interval and determines average RF power. Maintain the required pulse RF level while controlling frequency, pulse timing, attenuation, cabling, and other conditions that influence the stimulus reaching the device under test.

Narrow-Pulse Radar And EMSO Test Solution

Testing radar and EMSO systems with narrow RF pulses requires a signal source that can generate precise pulse widths, repetition rates, carrier frequencies, and RF levels while maintaining consistent pulse amplitude. The solution supports instrument-leveled pulses down to 40 ns, enabling engineers to apply controlled narrow-pulse stimuli to radar and EMSO components, receivers, and subsystems. Accurate pulse leveling helps maintain the intended RF level during each pulse, including low-duty-cycle conditions where peak pulse power can be much higher than average power. Engineers can configure pulse timing and RF parameters to match the operating conditions and limits of the device under test.
