The PPEB076 is a control board for a coherent receiver (ICR), following the MSA configuration. The pinout of the board is designed to work with the PPEB08x RF boards, but through customer customization can be made to work with any micro-ICR evaluation board. 

The control board can be controlled through a USB port , which installs as a serial interface. Simple serial commands are used to modify the device settings. Higher level controls are available through our GUI and our CLI (available for free download).

The functionality included on the board includes 4 TIA power supplies, VOA control voltage, 9 photodiode detectors, digital controls for MGC/AGC, shutdown and Bandwidth Control and 8 analog inputs for amplitude control. Several lower level inputs are available for LVTLL serial control and direct access to the photodiode outputs.
