DL708 (701810)

370 × 260 × 183mm 6.8kg

(14-5/8 × 10-1/4 × 7-1/4" 15.0 lbs)

The DL708 is designed for measuring multi-channel iso­lated physical signals. The DL708 has the same ease of op­eration and superb portability of the DL1500 series digital
oscilloscope with the addition of a large color display. The
modular inputs provide flexibility for various applications.
The new DL708 provides data acquisition and recording
technology to measure signals ranging from slow changing
temperature to high-speed MHz signals. One instrument
will provide a wide range of measurements.

FUNCTIONS

■ WAVEFORM CAPTURING FUNCTIONS

Capture signals with a conventional oscilloscope func­tions. You can set the time axis, voltage axis and trigger
while observing a waveform.

● Capturing Signals with Long Memory

You can capture signals using either the standard 400 k
words of memory or the optional long memory of up to
16 M words. This long memory lets you record wave­forms over a long period of time without having to reduce
the sampling speed. You can home in on the details of
the captured signals by using the zoom function or the
long copy function.
You can easily save the captured signals to a large capac­ity medium such as the internal 1.2 GB HDD (optional),
or an external 230 MB MO drive via a SCSI interface (op­tional).

● A Wealth of Trigger Functions

The DL708 supports an enhanced trigger which is de­fined as a combination of parallel patterns, in addition to
the normal edge trigger. You may set threshold values of
A and B for each channel, then set the trigger using a
combination of H (High), L (Low) and X (don't care).
The A and B parallel patterns may be set independently.
When setting the Edge ON A trigger, you can combine
the rising and / or falling edge of the specified signals.

● History Memory and Sequential Store

The history memory and sequential store function divides
the internal memory, enabling you to record the input sig­nals a number of times. History memory will allow you
to recall up to 1000 previous display screens.
The sequential store function is handy for capturing series
of high-speed events generated at intervals of a few ms or
less. Sequential store eliminates the process of displaying
each captured waveform, so the signals are captured with
a very short dead time. You may assign the number of ac­quisitions in advance and the captured waveform is dis­played after the set number of acquisition.

9

● Envelope

The envelope function always records the peak values of
the input signals at the maximum sampling speed, regard­less of the observation time. This is useful when observ­ing surge signals which occur intermittently over a period
of several minutes or several hours.
When the envelope function is used, the sampling speed
differs depending on the input module

interval at least equal to the delay setting has elapsed (condition B is ignored during
the delay time).

Enables an edge trigger on another input during the interval when trigger condition
A is true.

Causes a trigger when any one of the individual channel conditions set with the
patterns goes true.

Causes a trigger when trigger conditon B (a pattern) has gone true and remained
true for an interval equal to or longer than the set time, and then goes false.

Causes a trigger when trigger condition B (a pattern) goes first true and then false
within an interval shorter than the set time.

Causes a trigger if trigger condition B (a pattern) goes true and remains true for the
time set.

Causes a trigger if a signal falls inside a window defined by upper and lower
thresholds, or if the signal falls outside the window.

DL708

■ WAVEFORM ANALYSIS FUNCTION

● Measurement of 26 Kinds of Waveform Parameters

The DL708 automatically computes the maximum and
minimum values, RMS value and other voltage-related
parameters, as will as frequency, rise time and other time
axis parameters. These automatic measurements are use­ful for analyzing waveforms and are unaffected by human
reading errors.

● Cursors

In addition to the horizontal cursor for measuring the
voltage axis and the vertical cursor for measuring the time
axis, the DL708 has a marker which can be moved over
the captured waveform. The marker can be moved to the
zoom screen which displays an enlarged waveform seg­ment. This allows you to measure the time difference or
potential difference between two points with high time
resolution.

● FFT Analysis Function

The standard DL708 supports a power spectrum of up to
10,000 points. With the optional user define computa­tion function, you can also use various functions such as
linear spectrum and transfer functions.

■ WAVEFORM DATA RECORDING FUNCTIONS

● Real-time Hard Disk Recording (with Optional Internal

Hard Disk)

By using an internal 1.2 GB hard disk, you can record in­put signals in real-time. You can also record signals con­tinuously over several days.

9

● Inter-channel Computation

The standard instrument supports addition, subtraction,
multiplication, FFT (power spectrum) and phase shift
computations (addition, subtraction and multiplication
are performed after correcting the phase difference be­tween channels). By installing the user defined computa­tion function, you can freely define computation formulas
incorporating a wide range functions. Trigonometric
function, differential, integral, square root and digital fil­ter functions, as well as the usual four arithmetic opera­tions are available.

● Output to an External Printer or Plotter

(You can record several pages of waveform data using a
printer.)

The DL708 can be connected via the Centronics interface
to an external printer. You can record data on plain paper
instead of thermal paper, eliminating the need to make
copies of thermal paper printouts to preserve data
records. You can also print onto several pages data
which was recorded over a long period to the internal
memory or the hard disk. You can even make a copy of
the screen using an external plotter which supports HP­GL, via the GP-IB or RS-232-C interface.

● Output to The Built-in Printer

Data can be sent to the built-in printer in one of three
modes, display hard copy, long copy, and real-time re­cording. In the display hard copy mode, the image dis­played on the screen is sent directly to the printer. In the
long copy mode, an enlarged version of the waveform in
memory is printed. In the real-time recording mode, the
input signals are recorded directly to the printer in real­time. The maximum chart speed supported in the real­time recording is 20 mm/s.

INDEX

■ CONNECTING THE DL708 TO PERIPHERAL UNITS

● SCSI Interface (optional)

With the DL708, you can save waveform and panel set­ting information to an external hard disk, ZIP drive or
MO disk. Or, if the optional internal HDD is installed,
you can transfer the contents of the internal disk directly
to a Windows 95 environment by connecting the DL708
to the PC via an SCSI cable.

● 3.5-inch FDD

You can save the DL708 panel setting information and
waveform data to an FD in the MS-DOS format. You can
then use the waveform data off-line in a PC. By using
software such as Excel, you can save waveform data in
the ASCII format so that data can be read directly.
You can also save data in five kinds of image files, HP-GL,
ThinkJet, PostScript, TIFF, and BMP. You can then read
these files into word processing software on a PC to create
reports containing waveforms.

● VGA Interface

By simply connecting the VGA video output to a PC
monitor, you can display waveforms on a large screen
monitor. By using a commercially available VGA-to­NTSC or VGA-to-PAL converter, you can record display
data to a video recorder over a long period of time.
