6.4.18.8 Query ADC Hardware Gain Settings — AIOgetHWADCchanGain

Gets the hardware gain settings for a group of ADC channels. This is only supported on

certain cards.

SUPPORTED IN VERSION 4.10 ONWARDS.

i = AIOgetHWADCchanGain (h, Group, pGains)

where h short: board handle as issued by the

registerBoardEx function.

Group short: ADC channel group.

pGains pointer to unsigned long: pointer to unsigned

long variable which will be set to channel gains

value which depends on the card type.

For PCI230 and PCI260:

bits 1 – 0: gain for channels 0 and 1

bits 3 – 2: gain for channels 2 and 3

bits 5 – 4: gain for channels 4 and 5

bits 7 – 6: gain for channels 6 and 7

bits 9 – 8: gain for channels 8 and 9

bits 11 –10: gain for channels 10 and 11

bits 13 – 12: gain for channels 12 and 13

bits 15 – 14: gain for channels 15 and 14

Value Unipolar range Bipolar range

0 0 – 20V* ±10V

1 0 – 10V ±5V

2 0 – 5V ±2.5V

3 0 – 2.5V ±1.25V

E. . Saturates at about 12V.
