Is it save to use digital output as a digital input signal for another channel

[Hongkun]

Hi all,

I know this is a stupid question, but I do not have other signal generator by hand. So what I want to know is, can I use the digital output signal of my USB-6001 as an input signal for the same device but on other digital port? I did not try out directly because I do not want to burn the device down......

Thanks

Done all of the time. No problems.

I do loop backs all the time, especially in my test systems as a way of making sure my signal is making it to the UUT pin.  I typically throw in a 10k resistor just in case, but I have never had an issue.
