3. The LS 22 SE is populated with either one two or three channels Each channel implements either a spectral display centered at 70MHZ or a digital oscilloscope For each channel a Xilinx FPGA controls these functions and interfaces them to the local address and data bus of a PLX Technologies PCI9080 PCI interface chip The 9080 is the primary interface between the LS 22 SE and the computer system it is installed in The first channel 19 always populated and performs some additional functions not found in the other two channels LS 40 interface for example 2 2 Spectrum Analyzer Functionality To obtain a spectral plot a Numerically Controlled Oscillator NCO is initially programmed to run at a frequency that 1s equal to 59 3 MHz minus one half of the sweep range The NCO output has many extraneous frequencies that are knocked down by a passive LC filter The filtered signal drives the IF input of a mixer The other input of the mixer is a 70M Hz nominal IF output from a receiver or combiner and is brought in and amplified prior to mixing The mixer output 1s buffered and then passed through two 10 7 MHz ceramic bandpass filters The 10 7 MHz result is monitored by a LOGAmp The leveled output of the LOGAmp is not used but its VLOG output is conditioned and sampled by a LTC1199 10 Bit 500ksps A D converter During the acquisition of the spectral samples the controlling application issues commands that initializes the NCO to begin runn
