# My SAP Stream is Not Being Watermarked

### Scope

This document covers how to enable watermarking on your SAP (Secondary Audio Program) feed on AERO.100 and AERO.2000 processors.

### Configuration

In both the AERO.100 and AERO.2000 processors, the most common configuration is 5.1+2+2, which allows the processing of a 5.1 program (in output channels 1-6) and two stereo programs (in output channels 7/8 and 9/10).

Channels 1-6 are used for a station's main programming, while 7/8 are used for an SAP program.

### Watermarking SAP Program

Each of these outputs has a separate Nielsen encoder. While outputs 1-6 are for the main program, the 7/8 encoder inserts Nielson codes on the SAP program.

To activate:

1. Select **Instance 1**
2. Select **Nielsen Watermark**
3. Select **Channel 7/8**.
4. Enter the **SID** and **Check Digits**.

> [!NOTE]
> If inserting CBET (Critical Band Encoding Technology), the **CBET ID** and **CBET Check Digits** also need to be entered.
5. Click **Enable**.

When all of the information is valid and entered correctly, the encoder status shows it is running and it is inserting Nielsen codes in the output.
