Note	These values are approximate. For more accuracy use age1439_data_scale_get.
rangePtr	points to the current value of the range parameter for the selected signalPath. For the AGE1439_
	BB_PATH signalPath the returned range is always AGE1439_RANGE_15.
signal	determines whether or not the input signal is connected to the input amplifier.
	AGE1439_SIGNAL_ON attaches the input signal to the 50 Ohm buffer amplifier.
	AGE1439_SIGNAL_OFF redirects the input signal to a dummy 50 Ohm load, and feeds the
	buffer amplifier from an internally grounded 50 Ohm source resistance. The signal OFF setting is
	useful for making reference measurements without the signal applied. When using ac coupling the
	0.2 µF capacitor remains between the input connector and its 50 Ohm termination.
signalPtr	points to the current value of the signal parameter.
signalPath	Selects baseband AGE1439_BB_PATH or IF signal path AGE1439_IF_PATH. The IF path passes
	frequencies between 52 and 88 MHz. The range values above only apply to the IF signal path.
signalPathPtr	points to the current value of signalPath
