easyMap Tools™ -- How to Get the Free Registration Key for maps sources from Google Maps
easyMap allows you to create maps that pan and zoom on Anritsu handheld spectrum analyzers. This makes it easier to have the right map with you in the field. To fully utilize easyMap, a Registration Key, also called an API key, is required. With an API key, easyMap allows you to create maps with up to 7 zoom levels. This level of detail can be a great help when hunting interference, as it allows great detail at the tightest zoom levels, yet can cover a large geographic area. easyMap API keys may be obtained from either Google or MapQuest. For larger free downloads, they ensure that the terms of service are met.
This tutorial will show you how to obtain a Google API key.
