 Two numbers control the offset frequency of the ICE-OPL1: The divider setting N and the reference frequency. The divider setting N can be set to N=8,16,32 or 64. The reference frequency can be generated internally with a range from 50 - 240 MHz. A sequence of frequencies and frequency ramps can be programmed using OPL1's DDS Queue. Alternatively, an external frequency reference can be provided (external frequency must be from 32 MHz - 240 MHz). The offset frequency of the laser is given by the following formula: Two numbers control the offset frequency of the ICE-OPL1: The divider setting N and the reference frequency.
