RF Spectrum Analyser
These instructions are intended for users with basic
knowledge in RF technology. Please read the instruc-
tions carefully prior to operation and keep them for
later reference.
1 Safety Notes
The unit corresponds to all relevant directives of the EU
and is therefore marked with
.
Caution with high EM radiation
The RF EXPLORER allows to measure very
small signals down to −120 dBm. Therefore,
the antenna inputs are very sensitive and may be dam-
aged by an excessive radiation even with the unit
switched off. The maximum input level of +5 dBm must
not be exceeded. This level results e. g. at a distance of
approx. 1 m to a micro wave oven or at a distance of
approx. 10 cm to a mobile phone.
It is also absolutely necessary to prevent static dis-
charging via the antennas. For instance, firmly seize the
metal housing by one hand prior to attaching or touch-
ing an antenna by the other hand.
– For storage or transport, keep the unit in a metal box
and / or remove the antennas.
– In areas of very high RF radiation, connect one SMA
plug each with a 50 Ω terminating resistor to the
antenna jacks (e. g. the item SMA-150AW from
MONACOR).
•
The unit is suitable for indoor use only. Protect it against
dripping water, splash water and high air humidity. The
admissible ambient temperature range is 0 – 40 °C.
•
For cleaning only use a dry, soft cloth, never use chem-
icals or water.
•
No guarantee claims for the unit and no liability for
any resulting personal damage or material damage will
be accepted if the unit is used for other purposes than
originally intended, if it is not correctly operated or not
repaired in an expert way.

If the unit is to be put out of operation defini-
tively, take it to a local recycling plant for a dis-
posal which is not harmful to the environment.
Do not put defective rechargeable batteries into the
household waste but take them to a special waste dis-
posal (e. g. collective container at your retailer).
2 Overview
The RF EXPLORER has been designed to be intuitive and
easy to use. There is no need to read comprehensive user
manuals to take full advantage of its advanced function-
ality. Most of the complexity inherent to the spectrum
analyser is simplified by the firmware. For instance, you
do not need to adjust the resolution bandwidth (RBW)
each time you select a different frequency span. Actually,
you do not even need to know what RBW is.

Fig. 3 Spectrum display
The display shows an X axis and a Y axis,
X for the frequency in MHz and
Y for power in dBm.
Fig. 3 shows the frequency range from 2.408 GHz to
2.458 GHz and the amplitude (dynamic range) from
−10 dBm to −120 dBm.
Configuration settings such as amplitude reference
and frequency span are preserved between sessions. The
display shows a small marker
which indicates the peak
amplitude in the current frequency span. The first value
states the frequency at this point and the second value
the amplitude.
The display also shows a symbol
for the USB
USB
port (in case of connection to a PC) or a battery symbol
(when the on / off switch is set to ON). To recharge
the internal battery, connect the RF-EXPLORER / 6 to a
USB port; the on / off switch (2) must be in the position
ON! Then the USB symbol and the battery symbol are
displayed alternately.
