Contact the Peak Communications support department and request a Return Material Authorisation (RMA) number. 2. You will be required to provide to our support representative the model number, serial number and a detailed description of the problem.
  • Page 4 To ensure safety of operator the P7xxxR series of converters have been designed to comply with the following safety standard; EN 60950: Safety of information technology equipment, including electrical business machines Operation of the equipment in a non standard manner will invalidate compliance to this standard.
  • Page 5 This manual covers the installation and operation of the P7xxxR Up and Down frequency converters. A sample specification and review of generic specification parameters is incorporated in this manual, but is not guaranteed to be the latest specification or to represent all products covered by this manual, so please visit our website www.peakcom.co.uk for exact up to date specifications of the unit in question.
  • Page 6 1.2 Functional description The P7xxxR series will UpConvert a 70 ±18MHz (optionally 140MHz ±36MHz) signal to a frequency within the L-Band range of 950-1750 MHz or S-Band range of 2.025- 2.120GHz) and will DownConvert signals within the L-Band range of 950-2150MHz or S-Band range of 2.2-2.3GHz to 70 ±18MHz (optionally 140MHz ±36MHz).

Typical depending on model At 100Hz away from the carrier the average relative intensity of the carrier in CW mode at that point is 75dB lower than the centre frequency...
  • Page 8 Gain; +30dB ±1dB Attenuation; 0-30dB, stepped 0.1dB The gain of the converter can be set to have no gain (0dB) at maximum attenuation or a gain of 30dB at minimum attenuation. The finite gain set is specified to be within 2dB of the setting and the step size is 0.1dB. 1.3.10 Gain flatness ±1.5dB full band, ±0.5dB, across any 36MHz in band The slope and variation of power across the L/ S-Band should be within 2dB top...
  • Page 9 mixing with the input to give an interfering signal (4.9-3.4=1.5). A 5.15GHz LO is therefore used to avoid this problem and consequently the L-Band to 70MHz converter (P7xxxR) has to have INVERT enabled to preserve the spectrum. It is not normal to transmit inverted. 1.3.14 Auxiliary DC output.

  • Page 11 Operation Remote control is available from the front face connections in RS232/RS485 or with optional ethernet control. All internal oscillators are fed from a single internal reference, which can also be locked to an externally provided 10MHz reference frequency to ensure the system is stable and the changeover from one converter to another, minimizes traffic interruption.
