Data and Clock Position

Your NI digital waveform generator/analyzer allows you to configure the subperiod time at which each waveform sample is generated or acquired. This subperiod time selection is referred to as the data position. You can also configure the position of the exported Sample clock (clock position).

Configuring data and clock positions allows you to use your NI digital waveform generator analyzer for many common applications including, among others, measuring set-up and hold times, measuring propagation delays, and maximizing the timing margins among high-speed data transfers.

Some NI digital waveform generator/analyzers also support data deskew which allows you to specify the timing delay after the Sample clock rising edge when the device generates or acquires a new data sample. Data deskew is applied at all times, regardless of the value of the data or clock position, and it is expressed as an absolute time (in seconds). Refer to the data deskew topic for your device for information about valid values.
