  • Page 55 Instrument Design and Functional Description R&S FSH Tracking generator (Model 1145.5850.13/23/26 only) The LO frequency of the 1st mixer is routed via isolation amplifiers to the TG mixer. The other input of the mixer is a fixed frequency of 4031.25 MHz generated with a VCO locked to the TCXO frequency. The resulting IF signal is routed to the generator output connector.
  • Page 56 R&S FSH Instrument Design and Functional Description Processing of measured data detectors The measured data is processed in two dedicated ICs to reduce the sample rate of the input signal to a value that can be handled by the hardware. The DDC converts the digital IF signal to I/Q base band and filters the base band signals using low pass filters with programmable bandwidth.
  • Page 57 Instrument Design and Functional Description R&S FSH Detectors The R&S FSH uses a detector for the positive peak and the negative peak value. In the “sample” mode the measured value is routed directly to the display. In the RMS“ mode the detector determines the rms value of the input signal for one specific point in the display during the measured time.
