1.Summary
EM5030/EM5030LF series probe set contains 7 probes specially designed for testing magnetic
field. These probes are used to locating the interference source in EMI pre-compliance debugging
and can effectively shield the interference from electric field. EM5030’s frequency range is
between 30MHz~3GHz, and it has 4 types of probe head shapes.EM5030LF’s frequency range is
9kHz~50MHz, with 3 types of probe head shapes.
EM5030E series probe set contains two probes specially designed for testing electric field,
with frequency range from 30MHz to 3GHz. They are mainly used for locating the electric field
interference source, and the rest of the probe body is shielding design.
The probe is directly connected to the spectrum analyzer or oscilloscope with 50Ω BNC cable.
When the radiation or the conduction disturbance of the product surpass the standard, users can
use the near field probe to search for the certain component or circuit generating the interference
of certain frequency by measuring the coupling channel between the module and the signal shifting
speed, RF voltage of the evaluating system. When the interference signal is relatively weak, users
can improve the system sensitivity with the EM5020A(20dB attenuation) or EM5020B(30dB attenuation)
pre-amplifier.

1. Summary
EM5020A/B pre-amplifier 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.

5. Using Steps
Connect the output interface of the pre-amplifier to receiver or spectrum analyzer
Connect pre-amplifier power supply
Connect input signal (Please be sure that the input signal power doesn’t exceed the max input power of the
amplifier)
6. Caution
Connect the pre-amplifier before plug power cable in.
Do not connect the pre-amplifier if you do not know the max level of the signal. Max Input power of the
EM5020A is 13dBm, EM5020A is 15dBm. I t may be damaged if the input level exceed the Max Input
