Transient limiters protect EMI receivers and spectrum analyzers from transients, or random surges of energy. EMI receivers and similar electromagnetic susceptibility devices are routinely injected with bursts of energy as part of EMC testing, and as a result, may experience damage via intense feedback. A transient limiter is an accessory which limits the power traveling to the EMI receiver, safeguarding it against destructive levels of EMI. The limiter effectively creates a low pass filter which halts too high of voltage. EMC testing in industries like the military, aerospace, medical, automotive, semiconductor, and many other fields rely on transient limiters to protect their equipment.
