Product Manual  

– PPEB700 

 

 

The PPEB700 evaluation board is a convenient tool to control tunable lasers in the ITLA 
and micro-ITLA form-factor. It provides the following functionality: 

  Mechanical base for mounting an ITLA (1 position) or micro-ITLA (2 positions) 

  Fan with on/off switch to cool the mechanical base 

  +3.3V, -5.2V and +1.8V internally generated voltages 

  Switches to select between internal and external voltage supply 

  Wire terminal input for external power supplies and TxTrace 

  Selectable Micro-USB and RS-232 communications interface 

  LED indicators to monitor power supplies 

  LED indicators to monitor hardware lines (SRQ, DIS, RST, MS) 

  Switch to control hardware lines (MS, DIS, RST) 

  Wire terminal output for hardware lines
