The RF component of the testing instrument
is shielded against interference by an inter-
nal metal box at the antenna input (shielding
factor ca. 35 - 40 dB).
1) Volume control of the speaker for the
audio analysis. While using the signal
patterns
. - whose sound levels are
directly proportional to their field
strength – for analysis, the volume con-
trol should be turned completely to the
left.
2) Switch for selecting signal assessment.
Default setting: Peak value
3) Connector socket for antenna cable.
The antenna itself can be fit vertically
into a slot at the top end of the RF ana-
lyzer.
4) Switch for selecting measurement
ranges
fine = 19.99 mW/m²
medium = 199.9 µW/m²
coarse = 1999 µW/m²
The factory setting is in uW/m² (indicated through
a little bar at the bottom of the display) Amplifier
and attenuator available (each factor 100 ) Please
contact us.
5) On/Off Switch. At the uppermost posi-
tion
. a signal proportional to the
field strength is added. At the middle po-
sition
. the audio analysis is enabled
(1).
6) The RF analyzer is equipped with an
Auto-Power-Off-Function in order to pre-
vent unintended discharging of the bat-
tery.
