Output Circuit and Output Waveform. Figure A-13 shows a diagram of the output circuit. After passing through an output resistance of 50 W, the buffer output proceeds to the output connectors. The AWG2021 can be used without terminating the receiving (user) side with a resistance of 50 W, but when waveform distortion is great the 50 W termination is required.

The skew of the data output is held to ±2 ns between same channel, and is held to ±4 ns between CH1 and CH2. See Figure A-14. This figure shows the specifications for the waveform at the output connector when a cable is not being used.
