Type (amplitude modulation)
Selects the amplitude modulating waveform generated by the system controller.
Select either Sinusoidal, Triangle, Sawtooth or Inverse sawtooth.
Frequency (amplitude modulation)
The frequency of the internal generator amplitude modulation signal can be
adjusted. The range of frequency adjustment depends on the signal type:
•
Sinusoidal or Triangle – from 0.008 to 100000 Hz
•
Sawtooth or Inverse Sawtooth – from 0.001 to 200 Hz
To adjust the frequency, use either the slider or the text input field at the upper
right corner of the slider.
Max Power
Use the slider or text input field to set the modulation signal’s power level in
percent.
Modulation depth
Use this slider or text input field to set the maximum deviation in percent that the
modulation signal affects the optical output power. A lower value reduces the
modulation achievable and vice versa for a higher percentage.
Ethernet
Configures the network settings of the system when using an Ethernet
management connection. Configure the settings in this panel first (over USB)
before setting up a network connection in CONTROL following
Procedure 3 on
page 45 .

System IP address
Enter the IP address assigned to the ACOUSTIK system. Note that the IP address
must be reachable from the subnet that the PC with the CONTROL application is
connected to.
System port
The System port sets the port address the ACOUSTIK uses for reception of TCP
or UDP packets. The System Port address set in the network connection of
CONTROL must match this address – default: 10001.
