WESTEK Electronics has released the Bantam Instruments model 401B personal spectrum analyser. It is suitable for EMC precompliance testing for a range of radio frequency applications including wireless LANs and modems and paging systems.
Field strength measurements are made in dBV/m. The user selects the EMC standard specification appropriate to the task from the stored testing protocols. These protocols include CISPR 11-EN55011 Class A and B and CISPR 22-EN55022 Class A and B. The acquired spectrum is displayed together with limit lines for the relevant standard.
The 401B has four measurement accessories: an active E-field probe, a H-field probe, an active antenna and a preamplifier. The probes have a frequency range from 30MHz to 1.024GHz.
