Any counter inside 5133

[alex.]

We are trying to use USB DAQ 5133 to collect some pulse waveform.

Beside the single pulse waveform, we also need to record the starting time phase of the pulse according to a 50Hz time reference.

Originally, we do like below 

- CH1, random single pulse input, record pulse waveform, trigger by voltage level.

- CH2  a standard reference 50Hz waveform as attached.

-When triggered by CH1, it will record data for both channel. From CH2, we can get the amplitude value, then we can convert it to the phase time as the drawing.

Now we want to improve the system,  can we use the PF1 for trigger and somehow use a counter in 5133 to count the pulse's arriving time, then CH2 will be saved. We do not want to collect every 20ms data, since 5133 transfer back slowly through USB and may not be able to collect 20ms cycles continouesly.

Any suggestion?

I think you can use a "62" series.

The 5133 has 100M sampling rate. It can record sharp pulse shape. Also the USB is easy to integrate. That is why we really want to use 5133.

According to the datasheet of the 5133 there's no counter in that device

Why do you want/need to improve the system? Do you miss some pulses or what?

Becasue now the time reference ocuppy 1CH, actually 2 channels for data collecting at same time is needed.

If I can use the PF1 for trigger and use some counter inside, then I can use the both 2 channels for data collection.
