Saelig has introduced its new JRE TVK isolation tester, designed to help verify the proper shielding isolation of radiofrequency (RF) enclosure test set-ups. The testing consists of a sensitive, handheld spectrum analyzer and a high power 2.45 GHz test signal source that can measure enclosure isolation down to less than -100dB. The isolation tester also requires no adjustment, eliminating complicated spectrum analyzer adjustment or erroneous readings.
