Command Name

Query Attenuation

 

 

 

 

 

 

 

Command Format

81h

 

 

 

 

 

 

Description

The Query Attenuation command returns the current attenuation value as a 2-byte (16-

 

 

bit) value.

 

 

 

 

 

Example

The following example shows how to translate the HIGH_BYTE-LOW_BYTE

 

 

returned value into a dB attenuation value:

 

 

1.

0Dh & 6Fh = 0D6Fh

HIGH_BYTE and LOW_BYTE value to

 

 

 

 

hexadecimal value.

 

 

2.

0D6Fh = 3439

Convert hexadecimal value to an integer

 

 

 

 

decimal value.

 

 

3.

3439 / 100 = 34.39

Divide by 100 to convert to dB value.
