BUG in latest f/w, 02.01
Delayed sweep malfunctions.
To reproduce:
Ch2 must be enabled, Ch1 optional
acquire: 7M samples, normal
trigger: ch1 or not important, Auto or Normal seems to have no effect
main timebase 500us/div, delayed t.b. 100 us/div or something
Then when you move the delayed t.b. towards 1 ns/div all seems well until you select 1 ns/div..
It locks up for about 10 seconds, no waveform update, no response to keys.
Then it comes good and lets you go back to 2ns/div
Of course this DS2072 is using the latest enable everything serial codes.
