Bird 4421 RF Power Meter

Range

(Rxx)

Function

Selects a measurement range list ed in F igu r e 29.

Remarks

If the selected range is outside the range of the connected power sensor, the
command is ignored.

Terminators

(Yx)

Function

Selects the characters that follow the end of a data string. Set x to:

return(CR) and a line feed(LF).

a carriage return(CR).

Remarks

Many controllers use the terminator sequence to recognize the end of an input
string. Using incorrect terminators can lock the bus.
