CONTROL settings
68
Frequency (internal generator - internal only)
When the wavelength modulation source of the ACOUSTIK controller is set to
Internal , the frequency of the internal generator 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.
Narrow and Wide modulation gain (internal source only)
You can use this slider to increase the gain of an external modulation signal input
applied to the Wav/- pins. Increasing the gain will directly increase the
wavelength modulation achievable with the signal (modulation depth).
Level (internal generator power - internal source only)
You can set the output power level of the internal function generator to between
0 and 100%. Use the slider or the text input field in the upper right corner of the
Level slider to adjust the modulation level.
Offset (internal generator - internal source only)
The offset of the internal modulation signal can be adjusted between -100 and
+100% depending on the modulation level. For example, if the modulation level is
set to 40%, the offset can be adjusted between -60 and +60%. The sum of the
modulation level and the absolute offset can be a maximum of 100%.
Phase shift compensation
Turning this setting ON, extends the modulation bandwidth when the Range
setting is set to narrow modulation gain.
Integrating Update Interval
The integrating update interval sets the update interval for a software integrating
function. The function is only available on X15 type BASIK modules with
Coupling
configured as DC and Range set to Narrow .
Signal output (module only)
Set this parameter to Enable to output a BASIK module’s internal generator
signal to the system backplane. Ensure the ACOUSTIK system is not supplying
the modulation signal and only one module has the parameter enabled.
Turning ON wavelength modulation on inserted BASIK modules
To enable wavelength modulation for all modules with the function, select the
ACOUSTIK system in the Device selector and in the status panel lower left click
the WL mod button. The indicator next to the button turns ON green. Clicking the
button one more time, turns off wavelength modulation on all inserted modules
(that have the function).
