On this CD the manuals are available in different languages Seite 3 von 53 Seiten 1.BASICS The family of electronic inclination measuring instruments is very well suited for all kind of precision measurement. Two configurations are possible I.Communication from the measuring instrument to the external display unit via cable Using this conventional configuration the data transmission between the measuring instruments (MINILEVEL NT und LEVELTRONIC NT) are connected to the external display unit (LEVELMETER 2000 or Levelmeter C25 (analogue model)) with cables II.Communication from the measuring instrument to the external display unit via radio module Using the configuration „wireless transmission“ the data will be transmitted via radio transmission to the external display unit (possible with LEVELMETER 2000 only) IMPORTANT:The MINILEVEL NT still can be used as stand alone instruments as well Depending on the country in which the units are used the respective available free to use frequencies are 433MHz or 902 MHz.

TheMINILEVELis equipped with anintegrated displayand can be used as a stand-alone instrument. It is however possible to connect it to a Levelmeter (E.g. LEVELMETER 2000) to receive remote display or to use it together with another instrument for differential measurement. Picture right: MINILEVEL NT with integrated radio transmission module MINILEVEL NTwith integrated radio transmission module TheLEVELTRONICinstruments are not equipped with an internal display and require therefore the connection to anexternal display unit.

Lagorce 1. Local Oscillator (LO) Realized with a VCO, a frequency synthesizer, a loop filter and a 100 MHz quartz (frequency stability between 0...50 °C, +/- 20ppm) as reference. Aim is that the VCO is subject to the quartz oscillator. To do this, the 10 MHz reference frequency and the VCO frequency are divided down to 100 KHz. These two frequencies supply a phase comparator which delivers cyclic pulses proportional to the phase difference of the two input signals. These pulses passing through a low pass filter are integrted and produce a DC voltage to control VCO. The quotient from the frequency divider connected to the VCO is programmable by I2C bus. The output frequency may be adjusted by steps of 100 KHz. The VCO consists of an integrated oscillator (SA621) with the loead of an adapted circuit, a/4 line coupled with a varicap. The applied voltage over the varicap fixed the output frequency of the VCO. 2. Transmission The LO is hooked up on the transmission frequency (906.7...910.3 MHz). The micro-controller delivers two square wave signals (Output Txdata). 9600 Hz when a Low is to be transmitted or 15000 Hz when a High is to be transmitted. To reduce the spectrum of the harmonics, the square wave signal has first to pass through a low pass filter. This attenuated signal (rounded edges) is injected on the varicap from the VCO and modulates so the frequency from the LO. The HF signal is strongly amplified (+25dB) by an integrated amplifier with filter in SWA technique (high attenuation of the harmonics) 3. Receiver An integrated Low Noise Amplifier (LNA) SA621 permits to extract the signal from the noise. This HF signal is mixed up with a signal generated by the LO to receive a signal of 10.7 MHz (FO) which can easily be filtered and amplified. Seite 3 von 3 Seiten The intermediate Frequency (FI) is filtered by two ceramic filters. The selectivity of the receiver depends on these filters (BP: -20 dB / 400 KHz). This filtered signal is strongly amplified and demodulated by an integrated circuit (SA626). The disadvantage of this technology is a generated second signal (mirror frequency) with a frequency value within the band of the FI-filters. The filters cannot reject this signal. The second function of the SAW filter behind the antenna is, to suppress the mirror frequency (rejection -30 dB). 4. Annex The antenna switch permits to branch the antenna to the transmitter or to the receiver. The micro-controller permits the interface with the serial In- and Outputs, to program the LO and to manage the power modes.
