Specifications and Characteristics
Operating Characteristics
Infinite Persistence Waveform data is allowed to continuously
accumulate on the screen, and remains until display is cleared.
Oversampling Filter On time/division settings when less than 500
points are acquired across the screen, a built-in digital filter
automatically reconstructs the data. This filter is a combination between
a (Sin X)/X and a Gaussian filter (also known as interpolation).
Time Base in Sequential Single-Shot
Used to view previously captured segments as defined in the time base menu.
You can exclude, select, or view individual segment numbers from any
channel. Viewing options include:
Normal Selection and viewing of any or all previously captured
segments.
Average Averages and displays previously captured segments into a
composite waveform.
Envelope Displays the minimum and maximum voltages of all
previously captured segments.
Dual voltage and time markers are available. You can independently assign
voltage markers to channels, memories, or functions.
Four independent functions are provided for waveform math. The operators
are +, —, x, vs, magnify, inv (invert), int (integrate), and diff (differentiate),
and FFT. You can use the vertical channels or any of the waveform memories
for waveform math. Sensitivity and offset for these functions are adjusted
independently.
