 -

 Shows the negative component of the RF signal but displays it in a positive orientation.

•

POS HALFWAVE

 -

 Shows the positive component of the RF signal.

•

FULLWAVE

 -

 Shows the positive and negative halves of the RF wave, but both are oriented in the positive direction.

•

RF

 -

 Shows the echo with no rectification.

3.

Press the function toggle or move the joystick (

) to select the desired rectification method.

4.

After completing your selection, move the joystick up or down (

) to navigate away from this function.
