f) python: pg.PrintStatus() should display "Channel x output: enabled" and "Channel 1: running" (!-> channel configuration)
g) LED OUT x is on (!-> channel configuration)
h) there is/are pulse(s) on the OUT x output
To isolate output stage (optical switch and fuse) error, you can use front panel LEMO connectors. When channel output is disabled (schematic: OUT_EN_x, python: CHx_OE), output is redirected from front panel connector to FMC feedback loop back to FPGA (schematic CAL_OUT_2). These signal are connected to the SVEC front panel LEMO connectors with this mapping:
