FUNCTIONAL DESCRIPTION

	The 1509and 1509J-series devices are mechanically variable, passive delay	IN	Signal Input
	lines. The signal input (IN) is reproduced at the tap output (TAP), shifted by an
		TAP	Variable Output
	amount which can be adjusted between 0 and TD, where TD is the device dash
		OUT	Fixed Output
	number. The fixed output (OUT) reproduces the input, delayed by TD, and must
		GND	Ground

be terminated to match the characteristic impedance of the line, which is given

by the letter code that follows the dash number (See Table). The tap output is unbuffered. The 3dB bandwidth of the line is given by 3.5 / TR, where TR is the rise time of the line (See Table).
