The FSWT fulfills the requirements for a TEMPEST measuring receiver. The intuitive, straightforward operating concept permits users to accomplish measurement tasks quickly and easily.<br><br>The FSWT is the right T&M instrument for applications that require checking the information content of even the smallest signals. With two equivalent, switchable RF inputs, up to 500 MHz measurement and analysis bandwidth and two independently settable analog outputs for video voltage and demodulators, it fits perfectly into the typical test setup and easily replaces older instruments. The FSWT can optionally be equipped with preselection and preamplifier in the base unit (5HU). Twenty-one switchable filters with very low insertion loss suppress even strong out-of-band signals. With preamplifier, the noise figure at 100MHz is only 1.5dB. The test receiver measures and demodulates even weak signals reliably.
