Analog voltage for the echo amplitude (echo in the monitor gate)

a) Rectified echoes

0 volt:	no echo in the gate;
	echo amplitude = 0% screen HT
2.5 volts:	echo amplitude = 128% screen HT

b) RF mode

-1.25 volts: echo amplitude = -64% screen HT

+1.25 volts: echo amplitude = +64% screen HT

Analog voltage for the sound path of an echo

a) MEASURE = 0 TO 1st

0 volt:	sound path = a-START;
	echo is exactly at gate start

1.25volts: sound path = a-START +0.5 a-WIDTH; echo is exactly at gate center

2.5 volts:	sound path = a-START + a-WIDTH;
	echo is exactly at gate end
2.5 volts:	no echo in the gate

b) MEASURE = MULTECHO

The output voltage corresponds to the ratio of the mea- sured wall thickness to the gate width. If there is no echo in the gate, the output voltage is 2.5 volts.
