General Approach

The order of your interaction with the decoder software in many ways mirrors the order of the
algorithms. You will:

Assign a protocol/encoding scheme, an input source, and a clock source (if necessary) to one of
the four decoder panels using the Serial Data and Decode Setup dialogs.

Complete the remaining dialogs required by your protocol/encoding scheme to decode
Transitions, Bits and Words.

Work with the decoded waveform and result table to analyze the decoded data.

While not required, we recommend the following general approach to decoding:

1. Set up the decoder.

2. Acquire a single burst of relevant data, then run the decoder.

NOTE: If the sampling rate (SR) is insufficient to resolve the signal adequately based on the bit rate
(BR) setup or clock frequency, the protocol decoding is turned OFF to protect you from incorrect
data. The minimum SR:BR ratio required is 4:1. It is suggested that you use a slightly higher SR:BR
ratio if possible, and use significantly higher SR:BR ratios if you want to also view perturbations or
other anomalies on your serial data analog signal.

3. Use the various analysis tools to verify that transitions are being correctly decoded. Tune the

decoder settings as needed.

4. Run the decoder on acquisitions of the desired length.

You can disable/enable the decoder as desired without having to repeat the set up and tuning
provided the basic signal characteristics do not change.
