Free running oscillator
The free running oscillator is an autonomous asynchronous trigger source described in detail in the
. Setting of the input multiplexers can be done using the serial RS485 or Ethernet
interfaces.
12.4. Pulse generator
There are sixteen pulse generators. Each of them is characterized by two parameters: pulse delay and
pulse width. The pulse delay can range from 0 µs to 1,023,000 µs with variable resolution. The pulse
width can range from 1 µs to 1,023,000 µs with variable resolution.
The diagram in
Figure 6: time diagram of pulse generator
describes the relationship between input
and output. As depicted, the rising edge of the input signal triggers the generator, while the falling
edge has no special meaning and can happen anywhere in time.

Setting of the pulse generators can be done using the serial RS485 or Ethernet interfaces.
12.5. Output multiplexers
The output multiplexers are used to send the inner signals to the output stages. There are sixteen
output multiplexers organized in a 24x16 routing matrix.
Each multiplexer can have its output selected from one of the following sources:
•
No selection
