DSP The following conditions can assert the FAULT LED from the DSP circuitry m Over temperature 2 5 V supply m Over temperature 3 3 V supply If any of these are in fault condition the front panel FAULT light will be lit and the local red LED DS550 will be lit Over temperature faults are reported in the diagnostic log so you can look there to see if the DSP is asserting the line and which supply is the root cause WVR6100 and WVR7100 Waveform Rasterizers Service Manual General Maintenance If the system is not running then check the voltage on the 2 5 V and 3 3 V supplies If these are good then check the temperature of the regulators U50 and U60 If they are hot to touch then they are overloaded or defective replace the main board Additionally there are LEDs DS260 DS261 and DS262 on the Power Good lines from each of the DSP secondary supplies If the supply has fallen out of regulation then the Power Good LED will not be lit Audio In 1 generation boards the audio fault LED is DS360 on the component side and DS0460 on the back of the audio board The back side of the board faces up when it is installed in the instrument The 219 generation board does not have a fault light instead it has one watch dog LED for each processor and one LED for the FPGA The LED for DSPO DS0310 blinks at 1Hz and the LED for DSP1 DS420 blinks at 0 5 Hz The LED for the FPGA DS0820 is dim if the FPGA is not programmed an
