Notice: 2/14/2023

It has come to our attention that a required National Instruments GPIB VISA Driver that was distributed at no charge is now fee based.
APT is determining if this product can be written around this driver dependency.
If this or any driver is required, the client is responsible to obtaining through NI (National Instruments) Sales Channels.

Until this is resolved, APT will place on hold any purchases (not processing any payments received) until further notice.

Thank you for your interest in American Probe & Technoloiges products.
