USB WLAN adapter on a PNA?

Now, this might sound like a bad idea on the surface, but has anyone tried and seen any problems with using a USB wireless network adapter on their PNA? - such as one of those stick-like types?

It would seem to be a convenient way to make printouts to networked printers from the PNA, but having a 2.4 GHz source might not be wise.

Anyone have any experience with this to see if this would be an acceptable scenario?

Thanks.

I never turn off my cell phone when using my PNA, and I haven't seen any ill effects (although it's not plugged into the USB port). The narrow tuning of the PNA and strong CW signal tends to prevent this. However, I have seen wireless data signals leaking into PSA measurements where the component was acting as a receiving antenna. If you are testing isolation of a component at 2.4 GHz be careful. We don't allow cell phones or other wireless devices in our manufacturing areas where sensitive testing is done.

A quick test would be to hook up a component, measure, plug in the wireless adapter, remeasure and look for any differences, especially around 2.4 GHz and harmonics.
