Hi,
Recently I had to collect some data from a two way serial bus. Not going into specific details I had four signals,
clock (1MHz) and TX and RX sent with this clock and one big enable signal when the transaction occurs.
I have MSO 4104 (5 GS/s and 10M points buffer) and using logic probes I was able to trigger on enable signal.
I found out that when using my horizontal setting and getting actually 5 MS/s i was able to get rather correctly clock and TX, RX (everything lower was getting rather bad results on pulse width of clock and data).
Problem here is that transaction takes about 5s and time acquired with this setting is less (2-3 s - can't rember exactly).
This means that I am not able to get and save whole TX,RX transaction.
Is it possible to somehow overcome this issue ? I wasn't able to figure out if it's possible to put a logic probe sample every 1 MHz clock cycle (trigger directly on the clock and save every sample to a buffer - can't really say if digital scopes can work like that - although it seems pretty simple).
Thanks in advance for any suggestions,
Best,
