Point

131 ATTENUATOR Set the function generator to an output of 1 kHz, 100 mV p-p sinewave centered at @vdc as seen on the oscilloscope. Connect the function

				generator’s output to Channel A of the counter. Set the counter’s
				LEVEL A and B to PRESET. HP5328AF/096/H42 trigger lights should
				be blinking.
	2			When the 9825A CONTINUE key is pressed, verify that the
				counter trigger lights stop blinking.
14	3	SEPARATE/		With function generator connected to Channel A of counter,
		COMMON		when CONTINUE key of 9825A is pressed, verify counter readout
		NORMAL/		as 1.000.
	4	INVERTED		With function generator connected to Channel B of counter, when
				CONTINUE key of 9325A is pressed, counter should display
				approximately 1.00 kHz (frequency of function generator).
15	5	COUPLING		Set the function generator to a triangular pulse output of 1 kHz at
				300 mV p-p with a +0.4 vdc offset (Figure 5-9).Connect signal to
				counter’s Channel A input. Counter’s Channel A and B trigger lights
				should be blinking.
	6			When the 9825A CONTINUE key is pressed, observe the counter’s
				trigger lights stop blinking.
16	7	SLOPE/		Set the function generator to a triangular pulse output of 1 kHz at
		TRIGGER		300 mV p-p with a +0.4 vdc offset (Figure 5-9).Connect the function
		LEVEL		generator’s output to Channel A of the counter. Set the counter’s
				LEVEL A and B to PRESET.
	8			When the 9825A CONTINUE key is pressed, observe Channel A
				and B trigger lights commence blinking.
	9	Channel	B	When the 9825A CONTINUE key is pressed, counter should
		+ SLOPE		display approximately 150µsec±75µsec (wide tolerance).
	10	Channel	B	When the 9825A CONTINUE key is pressed, counter should
		- SLOPE		display approximately 400µsec±100µsec (wide tolerance).
	11	Channel	A	When the 9825A CONTINUE key is pressed, counter should
		+ SLOPE		display approximately 400µsec±100µsec (wide tolerance).
	12	Channel	A	When the 9825A CONTINUE key is pressed, counter should
		- SLOPE		display approximately 150µsec±75µsec (wide tolerance).
