I made a simply test about HISTORY function on my SDS2102, software version 1.1.1.26.2, hardware version 2-2.
Time Base Re-arm time
1ns 123us
2ns 60us
5ns 32us
10ns 24us
20ns 28us
50ns 9us
100ns 17us
200ns 33us
500ns 59us
1us 118us
2us 220us
5us 526us
Hi Herman, can we get the death time of the scope from this?
If there are 10 div on horizontal display, when the time base is 1ns, the death time is 123us/(1ns*10+123us)=99.9919%
2ns 60us/(2ns*10+60us)=99.9667%
5ns 32us/(5ns*10+32us)=99.8440%
10ns 24us/(10ns*10+24us)=99.5851%
20ns 28us/(20ns*10+28us)=99.2908%
50ns 9us/(50ns*10+9us)=94.7368%
100ns 17us/(100ns*10+17us)=94.4444%
200ns 33us/(200ns*10+33us)=94.2857%
500ns 59us/(500ns*10+59us)=92.1875%
1us 118us/(1us*10+118us)=92.1875%
2us 220us/(2us*10+220)=91.6666%
5us 526us/(5us*10+526)=91.3194%
It shows that the SDS2102 has the shortest death time at 5us time base, not 50ns? Or just in History mode?
