Loop back routes from one AWG pin to another.
•
The SYNC CLK pin is also called the trigger pin. SYNC_DATA is
currently not used.
For details about these routes, see "Pin Connections with an
Analog Module's Multiplexer" on page 99.
Output Amplifier
2
The output amplifier adds the DC offset voltage to the signal from
the attenuator, and generates the inverse signal that is required
for differential output.
Attenuator
3
The attenuator adjusts the amplitude of the signal generated by
the digital-to-analog converter.
Filter
4
The filter is a low pass filter for smoothing the waveforms. This
filter removes harmonics from the signal. There are several filters
with different cut-off frequencies.
Digital-to-Analog Converter (DAC)
5
The DAC converts the digital waveform data transferred from the
waveform memory to the analog signal. The conversion is
synchronized to the data that is sent to the DAC by the conversion
clock provided by the timing generator.
Timing Generator
6
The master clock and trigger signal are input to the timing
generator. After receiving the trigger signal, the timing generator
starts to generate the conversion clock by dividing the master
clock and feeds the conversion clock to the DAC. The timing
generator also sends the start signal to the sequencer. The timing
generator stops to generate the conversion clock when the
sequencer is halted.
Sequencer and Waveform Memory
7
The sequencer controls the output sequence of the waveform data
stored in the waveform memory. The output sequence of the
waveform data is specified in the sequencer program that is
contained in the sequencer memory.
