Digital Storage Oscilloscope 61
HR Reduce random or uncorrelated noise in signal
display. The number of averages is selectable.
Disp Mode
YT
XY
Roll
YT format shows the vertical voltage in relation to
time (horizontal scale); XY format displays a dot
between CH1 and CH2 each time when a sample
is acquired, where the voltage or current of CH1
determines the X coordinate of the dot (horizontal)
and the voltage or current of CH2 determines the
Y coordinate (vertical). For detailed information,
refer to descriptions on XY format in the following
text.

Normal: For the oscilloscope model with the bandwidth of 100MHz, the maximum
sample rate is 1GS/s. For time base with insufficient sample rate, you may use the Sine
Interpolation Algorithm to interpolate points between sampled points to produce a
complete waveform record (4K by default).
Peak Detect: Use this mode to detect glitches within 10ns and to limit the possibility of
aliasing. This mode is valid at the SEC/DIV setting of 4µs/div or slower. Once you set
the SEC/DIV setting to 4µs/div or faster, the acquisition mode will change to Normal
because the sample rate is fast enough that Peak Detect is unnecessary. The
