Front Panel
Power button: Turns NetSDR on/off
Clip LED: Shows the analog to digital converter clipping state. When on, the ADC is experiencing a
signal higher than the capture range. It is advisable to increase the input attenuation until clipping
condition stops. It is perfectly normal for the clipping light to sporadically activate with impulse noise.
Busy LED: Shows connection status and operating mode:
Steady blinking indicates the active capture of radio signals using the ext. 10 MHz reference (optional).
Four blink pattern indicates radio operation with the internal reference oscillator.
Steady yellow indicates a TCP/IP socket is connected and radio is in idle state.
A 25 Hz pattern indicates an PLL error in the REF LOCK unit.
ON LED: Shows NetSDR power status.
