Specifications
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
Box average: Increases the A/D resolution by up to 4 bits (16 bits max.).
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)
The displayed waveform is expanded along the time axis (up to two locations can be zoomed at
separate zoom factors).
Auto scrolling: The DL850E/DL850EV automatically scrolls to the zoom position.
1, 2, 3, 4, 5, 6, 8, 12, 16 analog waveform windows
64 traces per display group. You can switch between four display groups.
Sampled points can be displayed through the use of dots (OFF), sine interpolation, linear
interpolation, or pulse interpolation.
Three graticule types to choose from
Scale values, waveform labels, the extra window, the level indicator, and the numeric display can
be turned on and off.
The X and Y axes can be selected from CHn and MATHn (Max. four traces × two windows).
Persistence mode
The currently displayed waveforms can be retained on the screen.
Snapshot waveforms can be saved and loaded.
The displayed waveform is cleared.
The data of a single waveform can be acquired at two different sample rates.
Maximum sample rate: 100 kS/s (roll mode area)
Maximum sample rate: 100 MS/s
Record length: 5 kpoint, 10 kpoint, 25 kpoint, 50 kpoint, 100 kpoint, 250 kpoint, 500 kpoint
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 DL850E/DL850EV stores the data to an internal hard disk or an
external hard disk that supports eSATA. Note that hard disks that can be
used are those whose disk partition style is MBR and the format is FAT32.
Specifications
CHn and MATHn can be turned on and off separately.
You configure the settings of all channels while displaying waveforms.
You can use a USB keyboard or mouse.
×0.1 to ×100 (varies depending on the module)
You set the scale using upper and lower limits or switch between different scales.
Waveforms can be moved in the range of ±5 div from the center of the waveform display frame.
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 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.
