Calculate how much they need to up sample so have enough points on screen - n. Insert n-1 zeros in between each original sample points and then filter with sinc filter (approximation of it )(ideal brick wall fs/2 in frequency domain) and the result is 1400 bytes shown on screen. 
Of course if we have sampled data on the current screen more then 1400 bytes no need to sinc interpolate.

Actually, the waveform display area is only 700x400 pixels on screen; the 1400 bytes are endpoints of vectors.

Yes - the same one as here.

Firmware upgrade of Agilent DSOX2000 series is much more simple... http://www.home.agilent.com/agilent/software.jspx?ckey=2014479&lc=eng&cc=CZ&nid=-33575.970747&id=2014479

--- Quote --- To update your oscilloscope's firmware, do one of the following:

    Place the file on a USB flash drive, connect it to the oscilloscope, press [Utility] > File Explorer, select the file; then, press Load File.
    If your oscilloscope is on the network: you can place the file on your computer, access the oscilloscope's Web Interface (see the User's Guide for details), click Instrument Utilities, select Firmware Version, browse to select the file; then, click Install.

After your oscilloscope's firmware is updated, check the calibration status: press [Utility] > Service > User Cal Status. If "Results: OK" is displayed, you do not need to recalibrate. If calibration is required, press the Start User Cal softkey.

There is even no talk about the uninterruptible power supply. No instrument damage warning. Probably Agilent uses an advanced firmware protection or something.
