Architecture and SignallingΒΆ

The UHFQA contains a number of functional blocks for signal generation and acquisition:

Many of these blocks can operate independently and can be synchronized with external signals via the trigger inputs and outputs. In order to control the relative timing of the signal processing in these different blocks, internal trigger signals are used. Namely, the Arbitrary Waveform Generator can issue trigger signals in order to start the integration units, the input monitor, or the internal oscillator. The following block diagram gives an overview of the interconnection of these different blocks and illustrates the function of key user interface settings found in the user interface tabs listed above.
