- Specifications -
Synchr oniz ed sam plin g is pos sibl e
for external signals (up to 10MS/s).
Furthermore, external trigger input and
output signals are also available.
The time axis can be modified by turning
a dial. Modifying the time axis alters the
sampling rate.
Use the jog shuttle knob like the one used
on video equipment to scroll or change
the settings of the waveform being
observed. The jog shuttle knob puts
smooth waveform scrolling right at your
fingertips.
