Roll mode
The instrument switches to roll mode display when the trigger mode is set to Auto, Auto Level, or
Single for the following time scale ranges. For details on the trigger modes, see “Trigger modes” in
section 6.2, “Triggering Section.”

Waveform Acquisition and Display
Item
Specifications
Acquisition modes
Normal, Envelope, and Averaging are available.
Normal:
Normal sampling without special processing.
Envelope: From the data sampled at the maximum real-time sample rate, the instrument
acquires the maximum and minimum values for each memory acquisition interval.
Average:
Averages normally sampled data over multiple acquisitions. Exponential averaging
is performed when the trigger mode is set to Auto, Auto Level, or Normal, and linear
averaging is performed when the trigger mode is set to Single. The trigger mode
is handled as Normal when N Single is specified. The attenuation constant for
exponential averaging and the linear average count can be set to a value from 2 to
1024 in 2
n
steps. Averaging cannot be used on logic waveforms. For details on the
trigger modes, see “Trigger modes” in section 6.2, “"Triggering Section.”
Sampling mode
Select from three sampling modes: real-time, repetitive, and interpolation. When you use a short
time scale that would cause the sample rate to exceed the real-time sampling maximum sample
rate with the specified record length kept constant, the instrument operates as follows:
For the maximum sample rates, see “Maximum sample rate” in section 6.1, “Signal Input Section.”
RealTime:
Achieves the required time scale by reducing the display record length.
Interpolation:
Performs interpolation sampling. If you decrease the time scale further and
the upper limit of the interpolation sampling rate is exceeded, the instrument
reduces the display record length to achieve the required time scale.
Repetitive:
Performs repetitive sampling. If you decrease the time scale further and the
upper limit of the repetitive sampling rate is exceeded, the instrument reduces
the display record length to achieve the required time scale.
High resolution mode
Improves the analog waveform S/N ratio by combining the high resolution mode and the digital
filter.
Improves the vertical resolution up to 12 bits.
