FPA Sub-type Identifier: (Bits 4 – 7) 

Range Reticle Enable: (Bit 8) 

Reserved: (Bits 9 – 14) 

Lock Memory Mirror Bit: (Bit 15) 

The following enumerations are used for the type and subtype codes: 

/* Fpa Type Enumerations */ 
enum 
{ 
 

FPA_NONE = 0,  

 

 

/* No FPA */ 

 FPA_DRS_U3000A, 
 FPA_SOFRADIR, 

  /* 

Ulis 

*/ 

 FPA_RESERVED, 
 FPA_INDIGO_9705, 
 FPA_INDIGO_9809, 
 FPA_INDIGO_0202, 
 
 

FPA_UNDEFINED 

 

 

/* x to 15 Reserved */ 

}; 
 
/* Fpa Sub-Type Enumerations */ 
enum 
{ 
 

FPA_9809_INSB = 0, 

 FPA_9809_INGAAS, 
 
 FPA_9809_UNDEFINED 
}; 

Type: UWord16 

Size: 4 Words  

Description:  Each word contains a filtered result of a corresponding ADC channel on the DSP.  Read 
only data member.  These filtered values have been shifted up one bit location for precision/rounding 
purposes.  It is necessary to divide the value by 65535 to get a properly scaled value to use in 
voltage/temperature equations. 

Index [0]: DSP Channel A0
