6.5 Features
Waveform Acquisition and Display
Item
Specifications
Acquisition mode
Normal:
Normal waveform acquisition
Envelope:
The peak values are held at the maximum sample rate regardless of the
Time/div setting.
Averaging:
The number of times to average can be set to 2 to 65536 in 2
n
steps.
Box average:
Increases the A/D resolution by up to 4 bits (16 bits max.).
Record length
1 kpoint, 2.5 kpoint, 5 kpoint, 10 kpoint, 25 kpoint, 50 kpoint, 100 kpoint, 250 kpoint, 500 kpoint, 1
Mpoint, 2.5 Mpoint, 5 Mpoint, 10 Mpoint, 25 Mpoint, 50 Mpoint, 100 Mpoint, 250 Mpoint, 500 Mpoint
(on models with the /M1 or /M2 option), 1000 Mpoint (on models with the /M1 or /M2 option), 2000
Mpoint (on models with the /M2 option)
Zoom
The displayed waveform is expanded along the time axis (up to two locations can be zoomed at
separate zoom factors).
Auto scrolling:
The DL850/DL850V automatically scrolls to the zoom position.
Display format
1, 2, 3, 4, 6, 8, 12, 16 analog waveform windows
Maximum number of
displayed traces
64 traces per display group. You can switch between four display groups.
Display interpolation
Sampled points can be displayed through the use of dots (OFF), sine interpolation, linear
interpolation, or pulse interpolation.
Graticule
Three graticule types to choose from
Auxiliary display on/off
Scale values, waveform labels, the extra window, the level indicator, and the numeric display can
be turned on and off.
X-Y display
The X and Y axes can be selected from CHn and MATHn (Max. four traces × two windows).
Accumulation
Persistence mode
Snapshot
The currently displayed waveforms can be retained on the screen.
Snapshot waveforms can be saved and loaded.
Clear trace
The displayed waveform is cleared.
Dual capturing
The data of a single waveform can be acquired at two different sample rates.
Main waveform
Maximum sample rate: 100 kS/s (roll mode area)
Captured waveform
Maximum sample rate: 100 MS/s

Hard disk recording
(when the /HD0 or /HD1
option is installed)
Maximum sample rate: Depends on the number of channels being used. 1 MS/s when 1 channel
is being used. 100 kS/s when 16 channels are being used.
Capacity:
Depends on the amount of free space on the HDD
Operation overview:
When waveform acquisition occurs according to the specified trigger
mode, the DL850/DL850V stores the data to an internal hard disk or an
external hard disk that supports eSATA.
* 10 MS/s when the High-Speed 100 MS/s, 12-Bit Isolation Module (720210) is not installed
Vertical and Horizontal Control
Item
Specifications
Channel on/off
CHn and MATHn can be turned on and off separately.
ALL CH menu
You configure the settings of all channels while displaying waveforms.
You can use a USB keyboard or mouse.
Vertical axis zooming
×0.1 to ×100 (varies depending on the module)
You set the scale using upper and lower limits or switch between different scales.
Vertical position setting
Waveforms can be moved in the range of ±5 div from the center of the waveform display frame.
Linear scaling
The linear scaling mode can be set separately for each channel (only for voltage, stress, and
frequency). It can be set to AX+B or P1-P2.
Roll mode
Roll mode is enabled automatically when the trigger mode is set to Auto, Auto Level, Single, or On
Start, and the time axis setting is greater than or equal to 100 ms/div.
