Info Engl. Evaluates each radio service separately
Additional features as compared to the FF3: * 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. * An additional high pass filter applied at 1100 MHz helps differentiating in areas with high levels in the TV bands. * 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.
Variable frequency filter (trap) VF2 convenient for any HF-Analyser from HF35C. For what-if analysis prior to shielding measures
* This filter allows the HF-Series of meters to determine the dominating frequency of the total pollution by suppressing the signal in question by a factor 100 (= 20 dB) * Full text is currently only available in German
Skittenstrømfilterene demper støy fre det elektriske anlegget ved at den fjerner uheldige frekvenser som rir på de rene sinusfrekvensene i strømnettet. Det er særlig sparepærer, lysstoffrør og alt av elektronisk utstyr som lager disse frekvensene. Skittenstrømen måles med en skittenstrømmonitor som puttes i vegguttaket. Man legger til filtere i den sammme kretsen til den ønskede effekten er oppnådd.
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
