Frequency range 9kHz - 3GHz
Gain (typically) 20dB
Flatness ±3dB
Max linear output power 10dBm
1. Summary
EM5020A/B preamplifier can be used with EM5030 near field probe to amplify the small signal from probe. The frequency range of EM5020A/B is 9kHz - 3GHz with a fixed gain of 20dB (EM5020A) / 30dB (EM5020B). It can greatly improve the sensitivity of system testing. The EM5020A/B can be powered by a standard USB power adapter (Standard Accessories) which is very easy to obtained, and it also can be very conveniently powered by the USB port of the spectrum analyzer or receiver. It can help the engineer to debug the electromagnetic disturbance source quickly and accurately with the EM5030 of CYBERTEK.
