Manual
High Frequency attenuator with a signal reduction of 20 dB
in the frequency range of 10 MHz - 10000 MHz. For attenua-
tion of field strength above the upper limit of the HF-Analy-
ser.
Attenuator 20dB with DC-Passthrough
This attenuator increases the upper field strength measurement range of the
HF-Analysers by a factor of 100 i.e.(Decreases the signal strength 100 times). If
the measurement range is set to maximum and the display indicates ("1..."), this
attenuator will allow the HF-Analyzer to accurately display the higher signal
strength. It is compatible with the following HF Analyzers HFE35C, HFW35C,
HF58B, HF58B-r, HF59B, HFW59B and HFE59B (here incl.). This attenuator is
recommended to be used on the least sensitive measurement range.
Assembly:
The preamplifier is screwed between the antenna cable and the antenna jack of
your HF-Analyser. If necessary use our snap-on tightening aid MZU0076. CAUTI-
ON: Tools SHOULD NOT be used for tightening the connections because over
tightening can damage the threads. The filter is usually attached directly to the
antenna jack. If required it can also be assembled on a 90 degree angle with an
optional available SMA elbow connector. (CAUTION: Do not fold the antenna
cables!)
The HF-Analyser supplies the amplifier with power. A green light-emitting diode
illuminates through the attenuator symbol on the filter.
on the HF-Analyzer's display is not on. The light-emitting diode still glows even if power supply is not sufficient for
proper function!
Interpreting the Displayed Measurements
HF58B, HF58B-r, HF59B, HFW59B and HFE59B:

When the attenuator is connected, set the "Adapter"
switch of the HF-Analyzer to "Attenuator -20 dB" (See pic-
ture on left). This activates the integrated automatic con-
version feature of the HF-Analyzer. The true signal
strength value can be read from the display without any
manipulation. The vertical line on the left side of the dis-
play indicates the correct measuring unit.
