The E7402A: In-House EMI Pre-Compliance Without the Lab Delay. For engineering teams facing tight certification deadlines, the E7402A is the instrument that moves EMI testing from a bottleneck to a routine. It covers 9 kHz to 3.0 GHz with automatic EMI measurement capability, a built-in preamplifier, and optional tracking generator — all in a 14.9 kg portable chassis. Business case in one line: One avoided re-spin pays for the analyzer. Early detection of radiated or conducted emissions — before PCB layout is frozen — is the single highest-leverage cost control in EMC compliance.
