3 Terms and Definitions

The terms and definitions defined in ISO 5577, ISO 22232-1 and ISO 23243 and the following apply to this document.

3.1

The maximum number of channels that can be used for transmit and/or receive in one trigger.

Note 1.A phased array ultrasonic detector whose maximum number of channels (see 3.1) can be activated simultaneously is equal to the number of instrument channels is represented as a parallel phased array ultrasonic detector.

3.2

Phased-array ultrasonic testing with a maximum number of simultaneously active channels less than the number of instrument channels and controlled by an internal multiplexing device meter.

Example. A 16/64 multiplexing phased array detector, the maximum number of channels that can be activated at the same time is 16, and the total number of available channels is 64.see picture 1.
