UPDATED:
Matt provided a great link on how to add emulators for all Samsung devices.
OLD:
To get the official Samsung Galaxy Tab emulator do the following:
- Open the Android SDK and AVD Manager
- Click on Available packages
- Expand the Third party Add-ons. There you will see Samsung Electronics add-ons.
- Once the add-on is installed create a new emulator. Under Target you will see the new Samsung Tab settings, select that.
That’s it!
