beregnet for instrumentene HFE35C, HF59B og HFE59B. båndbredde fra 27 MHZ – 3,3
GHz
# Ultra broadband
antenna for RF-Analysers UBB27_G3 suitable for: HFE35C, HF59B, HFE59B. The
outstanding parameters with regard to the frequency linearity and the
responsivity render this antenna a very useful equipment for broadband
measuring devices for the definition of the total exposure to high frequency
radiation.
* From 27 MHz to far beyond 3.3 GHz*: For the
measurement of the primary high frequency ranges: CB and amateur radio,
directional radio, TV and radio (digital and analogue), TETRA, GSM, radar,
DECT, UMTS, WLAN, and more.
* Overall (non-directional) reception:
Horizontal isotropic directional pattern – a fundamental feature for long-term
measurements.
* Compact construction: Identifies so-called
hot spots.
* To be attached directly onto the HFE35C or
the HF59B. *
* Limited in real terms by the frequency
response and specifications of the respective HF analyser.

Frekvensfilter FF3
FF3 er et bånpass filter tilpasset instrumentene HF35C og HF38B. Med dette filteret er det enkelt å finne hvilke strålingskilder som er dominerende. Ved hjelp av en glidebryter velger du den kilden du er interessert i (f. eks. DECT) og avleser på instrume.
Til HF 35 C, HF 38 B, HF 58 B, HF 59 B.
#Service-specific frequency filter FF3 Recommended for: HF35C, HF38B. The service specific filters always only show the preset radio service, and suppress all other frequencies.
Evaluates each radio service separately
* To be connected between the antenna cable and the antenna input socket of the measurement device (by the operator).
* Cascadable with all amplifiers and attenuators.
* Also allows a broadband measurement without additional transmission loss, which means the filter can remain attached to the measurement device.
* Comprises the most common sources of radiation.Very good selection of the chosen radio services.
* Possible exposures to sheath currents on the cable behind the filter can be additionally suppressed with the help of a free of charge modification of your HF-device. Please do not hesitate to contact us.
Frequency Range: ALL / GSM9 / GSM18 / DECT / UMTS / WLAN
Accuracy: Typical suppression of unwanted frequencies : > 25-30 dB, GSM1800 vs. DECT eff. 20-30 dB.
Power supply: 9 V battery

Engl. Info:
Evaluates each radio service separately.
Additional features as compared to the FF6: The 50-60 dB suppression of unwanted frequencies is unequalled in this product segment. It allows for a precise analysis of the selected frequency ranges.
With its additional filters for TETRA-BOS, DVB-T, as well as high and low pass combinations applied at 1100 MHz this filter is especially suited for our E-type measuring devices (as from 27 MHz).
To be connected between the antenna cable and the antenna input socket of the measuring device (by the operator). Cascadable with all amplifiers and attenuators.
Also allows for a broadband measurement without additional transmission loss, which means the filter can remain attached to the device.
Perfectly shielded against interferences.
Possible exposures to sheath currents on the cable behind the filter can be additionally suppressed with the help of a free of charge modification of your HF-device.
