Issue Details

I'm using a PXIe-5451 and I would like to configure the channels as single ended mode in LabWindows™/CVI™. 
How to do it?


 

Solution

Based on the PXIe-5451 specifications, you will need to configure it in main path in order to use it as single ended.

In order to configure it as Single Ended you will need to configure the analog output path as main path using the function:
niFgen_SetAttributeViInt32 (vi, "0,1", NIFGEN_ATTR_ANALOG_PATH, NIFGEN_VAL_MAIN_ANALOG_PATH);

Then, you will need to configure the channel as single ended using the function
niFgen_SetAttributeViInt32 (vi, "0,1", NIFGEN_ATTR_TERMINAL_CONFIGURATION, NIFGEN_VAL_SINGLE_ENDED);

and you will need to enable the signal generator as following:
niFgen_ConfigureOutputEnabled (vi, "0,1", VI_TRUE);


 

Additional Information

Note.- The maximum output levels from these connectors depend on the type of load termination. You will need to take care on the impedance when configure it as single ended.
Please look at the following documentation for more explanation:
