int board conﬁguration

Describes the schematic conﬁguration of the board.

int adc resolution

Number of bits of the ADC, set to 0 if unknown. Should be 14.

double nominal sample rate

Maximum sample rate. 2.5e8 = 250Msps for the Ndigo250M and 1.25e8 = 125Msps for the

Ndigo125M.

double analog bandwidth

1.25e8 for 125MHz.

int chip id

16 bit factory ID of the ADC chip

int board serial

Serial number with the year minus 2000 in the highest 8 bits of the integer and a running number

in the lower 24 bits. This number is identical with the one on the label on the board.

int ﬂash serial low

int ﬂash serial high

64 bit manufacturer serial number of the ﬂash chip.

int ﬂash valid

If not 0 the driver found valid calibration data in the ﬂash on the board and is using it.

ndigo bool t dc coupled

Returns true for the Ndigo250M.

int subversion revision

A number to track builds of the ﬁrmware in more detail than the ﬁrmware revision. It changes

with every change in the ﬁrmware, even if there is no visible eﬀect for the user.

char calibration date[20]

DIN EN ISO 8601 string YYYY-MM-DD HH:DD describing the time when the card was cali-
