USBRIO-7845R. Analog Output settling time

[Naveed_16]

hi.

i am using USBRIO-7845.

i have confussion about it ANALOG OUTPUT SETTLING TIME. According to data sheet, changing of LSB, its settling time cab be vary from 7us to 1.5us for 20V step.

in software, how i can change this LSB stuff. the settling time which i am achiveing is nearly 10us. i can compromise on accouracy but cant on Settling time

Regards

Hello Naveed_16,

The settling time specification in the user manual for the USB-7845R defines how much time it takes for a signal in a specific range with a specific step size to be accurate within +-16\+-4\+-2 least significant bits. For a signal with a +-10V range and +-20V step size it will take 1.50us for the reading to achieve +-16 LSB of accuracy, 4.00us to achieve +-4 LSB of accuracy, and 7.00us to achieve +-2 LSB of accuracy. This specification is defined by the hardware and cannot be changed in software. Your only option is to change the range and\or step size to decrease the setting time.

How did you determine that you are achieving 10us settling time?
