Title: Question of The Day 2
Post by Tom Roberts on Jan 28^th, 2008 at 4:50pm

When you are recording with PicoScope, what is the longest history that you can record?

Using PicoScope 6 and a 3000 series automotive scope:

33 minutes and 20 seconds of continuous data with a sample about every 1/1000 of a second. 17 and 3/4 hours into the scrolling buffer. At this long of a time base, during that 17 and 3/4 hours, you will collect 99.9% of the total data losing only .1% between the screens in the scrolling buffer.

Tom

Would we have to turn off a screen saver to use scrolling buffer captures that long? Then there is a sleep mode setting somewhere right?

Mick,

Yeah, you wouldn't want the PC to go to sleep but the screen saver shouldn't disrupt it. Just to be safe though, you could turn that off too. I have mine set up so it doesn't sleep if it's on AC power.

is this scrolling buffer being written to the hd? I would think hd activity would reset any sleep mode timer ..... unless sleep mode depends on user input.....

Quix,

With a program running and actively acquiring data, sleep mode will probably be skipped. Not sure in all cases though.

The scrolling buffer is using RAM.
