Programmable Gain on DAQCard 1200

[cvanloon]

Hello,

I am new to this stuff, so if I show ignorance, I appologize. I would like to adjust the programmable gain on the DAQCard 1200. How can I do this. I have labview  6i. Is there something I have to edit with the card properties in the "measurement and automation" program. I was reading the users manual and it gave a table of gain settings I could set it to. I would like to set it to gain setting 5.

Thanks for any help you can provide,

Chris

The DAQmx driver automatically selects the gain for an acquisition when the input range is specified.

In other words : the gain is defined indirectly by the range (max and min) of the signal. See here for examples and more details.

I forget to mention that you will find the device gain - range table on page A-1 of the DAQCard-1200 user manual.

JB's absolutely right that it is set based on the input range you specify in software.  For example if a card has a maximum input of 10V, and you specify a maximum signal of 5V, it will automatically choose the 2x gain (if it exists for that card) so it can have the most precise measurements.
