High-Speed Analog Input Mode
On the UDAS unit, the rate generator is able to provide rates from 0.477 conversions per second to 100,000 conversions per second. These conversions are either performed on a single input channel, or performed on a range of input channels by using the channel scanner (described below).
When the conversion is complete on the current channel, the channel scanner automatically selects the next channel. The term
Starting and Stopping the High-Speed Analog Input Mode
There are several methods to start and stop conversions available on the UDAS:
•Start with trigger, Stop with software
•Start with trigger, Stop after N samples
•Start with software, Stop N samples after trigger
•Start with software, Stop with software
•Start with software, Stop after N samples
Starting Conversions
To start the conversions, use either a trigger or a software command. The trigger can be an external digital TTL level input, or an analog input. For an external TTL signal, the slope (rising edge or falling edge) must be specified. Use the external input pin to provide this input.
