Made in Germany Functions and Controls The HF component of the meter is shielded against interfer- ence by an internal metal box at the antenna input (shielding factor approx. 35 – 40 dB) © Gigahertz Solutions GmbH... - Page 5 (Push and hold for 2 seconds or until the reading no longer drops) For HF58B-r and HF59B only: Switch for selection of the Video Bandwidth. Standard setting: “VBW Standard” Switches for rarely used functions are recessed in the casing of the instrument.

“overnight”. Major changes in exposure levels can, for instance, al- ready be caused by a transponder only being tilted down by a few degrees (e.g. during installation or repair works on cellular phone transmitters). In particular, however, the worldwide extremely rapid © Gigahertz Solutions GmbH... - Page 8 The supplied logarithmic-periodic antenna (or aerial), has excep- tional directionality. Thus it becomes possible to reliably locate or “target” specific emission sources in order to determine their con- tribution to the total HF radiation level – a fundamental prerequisite for effective shielding. © Gigahertz Solutions GmbH...
- Page 9 In order to avoid measurement values to be falsified by radiation sources from frequencies below 800 MHz when measuring with the LogPer antenna, the HF58B and the HF58B-r are equipped with an internal high pass filter at 800 MHz. As the HF59B picks up frequencies below 800 MHz, it has no inte- grated high pass filter.

Since there is no need to look at the display during an overview measurement, but only to listen to the audio signal, you can easily © Gigahertz Solutions GmbH... - Page 11 There is a factor of 100 between “med” and “max” thus allowing to display as large power flux densities as possible withouth having to apply an attenuator. For technical reasons the highest tolerances must be expected here. © Gigahertz Solutions GmbH...

- Page 15 As the standard please set the instrument to “Peak hold” and “VBW standard ” (default in the HF58B). The displays of the meters of this series show the sum of the total power density within the frequency range of the most common dig- ital radio services.

- Page 17 For the HF58B it is helpful to use the “-” (“minus”) setting for Peak hold to catch the short bursts. The HF58B-r and HF59B have a patented circuitry that allows for the exact measurement of the extra fast rise times of the bursts even in the “+”-setting for Peak hold.
