D. Measurement referred to high gain jumper setting, with limited environmental noise,
inputs and outputs terminated, output signals disabled, PCB grounded through SMA
ground. The specified noise floor measurement is calculated from the standard deviation
of 16k contiguous samples at full rate. (Typically full bandwidth std(Vn) < 2 mV). Noise
floor specification does not treat separately spurious spectral components and
represents time domain noise average referred to a 1 Hz bandwidth. In presence of
spurious components the actual noise floor would result lower.

S. Valid for low frequency signals. For input signals that contain frequency components
beyond 1 kHz, the full scale value defines the maximum admissible input voltage.
T. Jumper settings are limited to the positions described in the user manual. Any other
configuration or use of different jumper type may damage the product.
U. SMA connectors on the cables connected to Red Pitaya must correspond to the
standard MILC39012. It’s Important that central pin is of suitable length, otherwise the
SMA connector installed in Red Pitaya will mechanically damage the SMA connector.
Central pin of the SMA connector on Red Pitaya will loose contact to the board and the
board will not be possible to repair due to the mechanical damage (separation of the pad
