Counter Display Readout
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.
When the 9825A
CONTINUE
key is pressed, verify that the
counter trigger lights stop blinking.
With function generator connected to Channel A of counter,
when
CONTINUE
key of 9825A is pressed, verify counter readout
as 1.000.
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).
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.
When the 9825A
CONTINUE
key is pressed, observe the counter’s
trigger lights stop blinking.
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 the function
generator’s output to Channel A of the counter. Set the counter’s
LEVEL A and B to PRESET.
When the 9825A
CONTINUE
key is pressed, observe Channel A
and B trigger lights commence blinking.
When the 9825A
CONTINUE
key is pressed, counter should
display approximately 150µsec±75µsec (wide tolerance).
When the 9825A
CONTINUE
key is pressed, counter should
display approximately 400µsec±100µsec (wide tolerance).
When the 9825A
CONTINUE
key is pressed, counter should
display approximately 400µsec±100µsec (wide tolerance).
When the 9825A
CONTINUE
key is pressed, counter should
display approximately 150µsec±75µsec (wide tolerance).
