NI-9262 as a DAC module?

[hnchu]

Hi everyone,

I need some advice about the DAC module for my testing process. I designed an RF circuit (vector modulator) and I have to provide 5 bias voltages (V1~V5) to make it work! The testing scenario is described as follows. The DAC is controlled by computer with the input digital should be a random sequence (PRBS or so) while the analog output should be 5 voltages (V1~V5) in the range from 0~10V. The DAC should be programmable with a predefined lookup table (as demonstrated in the picture). I have some questions:

- I'm considering buying NI-9262 for this test but I'm just wondering whether NI-9262 can fulfill this test or not since I'm a newbie in NI equipment.
- Does NI-9262 come with Labview or any kind of free programming language since the budget is quite limited so far?

I really appreciate your help!

1. You will need a cDAQ chassis/carrier for your 9262.

2. You will program the 9262 using DAQmx.  In that driver, you just set the output voltage(s).  So I'm not sure where that fits in with your random bit sequences.

Dear crossrulz,

Thanks for your reply!

1. So NI-9262 is a module only and I need a cDAQ chassis/carrier (cDAQ-9171 or cDAQ-9174 since I prefer USB connection). => Solved!

2. The output voltages should be changed according to the input random bit sequence with a pre-defined lookup table. So is this possible to program (or create) that lookup table for NI-9262 (or NI-9262 installed in cDAQ chassis)? And the random bit sequence could come from PC or could be generated by any kind of block in DAQmx?
