TTL signal to analog waveform
I want to read the signal from a photomultiplier (TTL signal 3V, 9ns
wide pulses) and convert the reading into an analog waveform
proportional to the intensity of the light incident on the
photomultiplier.
The number of pulses given by the photomultiplier unit is directly
proportional to the intensity of the incident light (which varies more
or less sinusoidal with a frequency of about 50kHz).
I have a DAQ PCI-MIO-16E-1, and
labview 5.1.
I assume I have to use a counter input, to count the number of pulses,
but I don't know how to convert the output of the counter.vi into an
analog waveform.
Anybody has a clue?
Than you in advance.
