Hi All,
I have few questions on Agilent Oscilloscope (MSO6104A).
I need to capture 20 single ended I/O lines at 1.2V CMOS logic level,
toggling at 220 MHz from a test board. I want to use the logic analyzer in
MSO6104A (16 digital + 4 analog ) to capture the data lines continuously.
For this, I am using the IntuiLink Data Capture tool in Microsoft excel to
capture this data via a USB interface from MSO. But in MSO6104, at one time
I can capture only 50,000 points of what is present on the screen of MSO.
I request you to address my following queries:-
1. How I should use the MSO to capture more number of points when
compared to 50000. Is there a way to continuous capture of data in excel
sheet through which, I can capture the 220MHz signal for a time period of
50msec. I require this so that I have more data to analyze offline in
Matlab. At present 50000 samples is very less for analysis.
2. How do I change the digital capture for 1.2V CMOS logic level?
Because, I see the trigger is for TTL signals.
3. Is there any application note describing the above scenario.
Thanks in advance,
Regards
Nirmale G
