- Page 4 “low“, they do not go off completely, instead they become dimmer. The power for the active circuits of the UBB27 is supplied by the RF analyser (HFE35C or HF59B) through the antenna socket. The power consumed by the UBB27 alone is higher than that of the instrument itself.

Page 5: How To Perform Measurements
Power densities of horizontally polarized sources in the horizontal plane will be displayed as lower values by up to – 10 dB. To better analyze a horizontally polarized TV transmitter, turn the UBB27 hori- zontally with the ground plane in the direction of the transmitter (like a wheel rolling towards the source to be measured). - Page 6 The external attenuator DG20_G3, may be used with the UBB27 plus either HFE35C or HF59B. Accuracy By itself, the UBB27 inaccuracy range of +/- 3 dB extends from ap- prox. 85 MHz up to 3.3 GHz. The antenna continues to work beyond that, but with increasing attenuation.
- Page 7 Frequencies below 27 MHz are damped out by an internal, extremely steep high pass filter. NOTE: The UBB27 causes a noise of up to 5 μW/m² in the ”Min” range. With the HF59B this can be reduced significantly by using the “Pulse”...
