The SZB-190 generates the requiredvoltage/tone signals for the selection of H/V polarisation and high/low frequency sub-band.• Double Side Band. Mono Audio.• Microprocessor controlled. Access to adjustments and programmingcan be easily achieved through the SPI-300 programming-unit.• Designed to deliver a very low broadband noise floor so severalSZB-400’s can be simply combined together through the two directionalRF output ports provided, then fed into a broadband amplifieras the final driver. Only 1 channel gap required.• One single channel RF output from each modulator, or one multichannelRF output by installing the concentration line. The freeoutput ports need to be terminated using a 75Ω terminator. F femalevideo connector; RCA female audio connector.The SZB-190 may be used with anuniversal 1 output LNB. Power andvoltage/tone signalsfor polarity/bandselection are provided by the modulefrom its IF-Sat input port.Using a smallscrewdriver, place properlyeach microswitch 1 to 6 as indicated inthe table below :Voltage / Tone+13 VDC / 0 kHz+13 VDC / 22 kHz+18 VDC / 0 kHz+18 VDC / 22 kHzMicroswitch1 2 3 4 5 638CATALOGUE 2013 · IKUSI
