EMC pre-compliance testing with the TBTC0/1/2/3- radiated emissions

Terminate any of the two ports of the TEM cell with the 50Ω load, connect the DC-Block to the other port and connect it to the input of the spectrum analyzer or test receiver. Place the DUT under the septum and power it on. Reduce the input attenuation of the analyzer to 0dB and if available turn on the pre-amplifier to increase the dynamic range of the measurement. Reduce the resolution bandwidth to 9 kHz or whatever specified in the corresponding standard. Set the trace to max hold and let the analyzer run as many sweeps as may be necessary to catch pulsed or sporadic signals from your DUT.
