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

Høypass filter HP800_G3
High-pass filter suitable for: HFE35C, HF59B, HFE59B.#
The HP800 increases the measuring accuracy when measuring with the log.-per. antenna in combination with the extremely broad band devices HFE35C and HF59B(Filter included in the scope of supply of the HFE59B).
Why?
The log.-per. antennae are sensitive also for individual frequencies below the specified frequency range. These can be successfully suppressed with the filter, which in turn allows a significantly improved analysis of the measurements with a log.-per. antenna, as the measurements are not impaired by unidentified interference signals.
– This filter helps suppress the lower frequencies. It reaches an attenuation of more than 50 dB (= factor 100,000) below 600 MHz.
– All Gigahertz analysers specified above 800 MHz already come with a similar filter integrated in the basic device. This integration naturally makes no sense for the HFE-types.
– Adaptor plug to be connected to the antenna input socket.
Technical data:
– Accuracy: Attenuation: 10 MHz – 600 MHz < – 50 dB
– Pass band: 0 Hz, 800 MHz – 3000 MHz = -1 dB +/- 0.5 dB
– Return loss: > 12 dB
– Further Questions: Two years warranty
