/TR+
Control signal which switches on and off the Transfer Bias
voltage applied to the BTR. The Transfer Bias voltage is not
applied when this signal is High and applied when Low.
/TR-
Signal which switches the polarity of the Transfer Bias voltage.
The Transfer Bias voltage is positive when this signal is Low
and negative when High.
/DTS
Control signal which switches on and off the voltage to the
Detack Saw. The voltage is not applied when this signal is Low
and applied when High.
TR A/D
Monitoring signal which indicates the Transfer Bias current to
the BTR (Analog signal)
TR D/A
Control signal which determines the value of the Transfer Bias
current.
