Here is an application note about how to turn PWM outputs to analog outputs.
AN538 – Using PWM to generate analog output
The free iDAQTest&Log is a standalone ready-to-run software that can be used to test the
iUSBDAQ device and log analog input’s data and read back logged data for basic analysis. With
this software, user can browser through all the features in iUSBDAQ, such as read single analog
channel, multiple analog channels, streaming analog input data continuously for display and log
into file with or without external trigger, set DIO (digital I/O) directions and read/write DIO states,
program PWM output frequency and duty cycle, read counter etc. It's ideal for people who do not
want to write their own software. The newest version has added the offset and scale capabilities,
user defined X and Y graph units.  This allows the multiple graph display not only in voltage units,
but can also display in the real world units for sensors.
More information please check out the iUSBDAQ User's Guide. Below are some screenshot of iDAQTest&Log
software. All drivers, software can be downloaded here. We have also setup the iUSBDAQ FAQ (frequently asked
questions) for support.

For users who are looking for higher speed streaming throughput or add video into their data acquisition system
or looking for a standalone USB flash drive data logger, our new U1208LOG model will suit all these
requirements. Please check out
