Wideband Radar Receiver Calibration

Wideband radar receivers are used extensively in ES (Electronic Warfare Support), EA (Electronic Attack), and EP (Electronic Protection) systems. The test and calibration of these wideband receivers require the generation of a large number of calibration frequency points across their operational bands. As thousands of calibration points need to be established across many GHz of frequency, the ability to tune, settle and measure at very high speeds is highly advantageous.

The Spanawave/Giga-tronics 2500B is ideal for these data-intensive applications, providing fast frequency switching speed with no compromise in phase noise or haronmics performance.  The 2500B can step frequency in less than 200 µs for frequency increments up to 10 MHz.

Power level accuracy can be increased by using a power meter to measure the test signal amplitude. A fast reading power meter is needed to avoid significantly reducing the speed of the testing. Fast reading power meters with diode power sensors can achieve CW measurement speeds of about 600 µs per reading.

Time for stepping from 2 GHz to 18 GHz with frequency and amplitude changes at each step.
