Signal Acquisition and Screen Display
Item Specifications
Acquisition modes Serectable from Normal, Envelope, and Averaging.
Normal:: Normal sampling without special processing.
Envelope:: From the data sampled at the maximum real-time sample rate, the DL6000/
DLM6000 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 set to Normal for N Single. The attenuation
constant for exponential averaging and the linear average count can be set
to a value from 2 to 1024 in 2n steps. Averaging cannot be used on logic
waveforms. For details on the trigger modes, see "Trigger modes" in section
18.2, "Triggering Section."
Sampling modes You can select real-time, interpolation, or repetitive sampling mode. 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 DL6000/DLM6000 operates
as follows:
For the maximum sample rates, see "Maximum sample rate" in section 18.1, "Signal Input
Section."
RealTime:: Achieves the desired 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 DL6000/
DLM6000 reduces the display record length to achieve the desired 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 DL6000/DLM6000
reduces the display record length to achieve the desired 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.
Interleave mode Analog signal
input:
The DL6000/DLM6000 can double its maximum real-time sampling rate by
sampling using two A/D converters (even-numbered channels are turned off).
Logic signal
input:
(DLM6000)
The DL6000/DLM6000 can double its maximum real-time sampling rate by
sampling a single input signal with two logic signal converters.
Record lengths 2.5k Points/6.25k Points/12.5k Points/25k Points/62.5k Points/125k Points/250k Points/
625k Points/1.25M Points/2.5M Points/6.25M Points
History feature Automatically saves history waveforms (past waveforms that have been acquired using the
same acquisition conditions).
The maximum number of acquisitions that can be held is as follows:
2500 acquisitions (when the record length is set to 2.5 k points)
1600 acquisitions (when the record length is set to 2.5 k points, the trigger mode is set to
N-Single)
Replay: History waveforms are replayed automatically.
History accumulation (half tone, intensity, color grade)
History averaging: Acquired history waveforms are linearly averaged and displayed.
