4.7. Amplitude Control
The amplitude control allows the user to adjust the ramp amplitude from 1 to 30 V
peak to peak using a 10-turn trim pot. Note, the ramp signal is added to the DC
offset. This means that when the offset is set to 0V, the ramp will start a 0V and
increase to the amplitude limit setting. The amplitude is used to determine how far
the mirror will be scanned, or to set the spectral range of the optical head.
4.8. Rise Time Control
The rise time control allows the user to continuously adjust the scan rate from 0.01
to 0.1 s using a 10-turn trim pot. Note the rise time setting may be scaled by the
sweep expansion setting. For example: If the scan rate is set to 0.05 s and the
sweep expansion is adjusted from 1x to 100x then the scan rate will adjust to 5 s.
The scaling error is typically less than ±0.5%, providing excellent measurement
capabilities.
