Chapter 1 Overview
DSC-5300 Series Digital Oscilloscope is mini-type and portable bench type instruments,
which could be used for measuring as the GND voltage.
This Chapter shows you how to operate following tasks:
•Accidence of panel and Display information
•Simple checking of functions
•Matching probes attenuation coefficient
•Probe compensation

1.1 Overview of Panel and Display Information
1.1.1 Front Panel
It is important for you to understand the DSO’s front panel before operating it. The
following contents are the brief introduction for the front panel function, which is useful
to be familiar with the operation of the DSC-5300 Digital Storage Oscilloscope in short
time.
The oscilloscopes provides an easy-to-use front panel to convenience users to operate
them, the panel contains knobs and buttons. There is a list of five ashen buttons as menu
operational buttons on the right of display screen. You can set different options of the
current menu in virtue of them. Other buttons are function buttons; you can enter
different function menus or obtain given function application in virtue of them.

1.2 Function Checking
When you check whether or not the oscilloscope could work smoothly, please operate
as following:
1. Power On the oscilloscope.
Press “DEFAULT SETUP” to show the result of the self check. The probe default
attenuation is 1X.

2. Set the switch to 1X on the probe and connect the probe to channel 1 on the
oscilloscope. To do this, align the slot in the probe connector with the key on the CH 1
BNC, push to connect, and twist to the right to lock the probe in place. Connect the probe
tip and reference lead to the PROBE COMP connectors

2.1 Menu and Control Button
Showing as the following picture:
Picture 2-1
■Channel buttons (1, 2): Press a channel button to turn that channel ON or OFF and
open the channel menu for that channel. You can use the channel menu to set up a
channel. When the channel is on, the channel button is lit.
■MATH: Press to display the Math menu. You can use the MAH menu to use the
oscilloscopes Math functions.
■REF: Press to display the Ref Wave menu. You can use this menu to save and recall
four or two reference waveforms internal memory.

11
■HORI MENU: Press to display the Horizontal menu. You can use the Horizontal menu
to display the waveform and zoom in a segment of a waveform.
■TRIG MENU: Press to display the Trigger menu. You can use the Trigger menu to set
the trigger type (Edge. Pulse, Video, Slope, Alternative) and trigger settings.
■SET TO 50%: Press to stabilize a waveform quickly. The oscilloscope can
set the trigger level to be halfway between the minimum and maximum
voltage level automatically. This is useful when you connect a signal to the
EXT TRIG connector and set the trigger source to Ext or Ext/5.
■FORCE: Use the FORCE button to complete the current waveform acquisition
whether the oscilloscope detects a trigger or not. This is useful for Single acquisitions
and Normal trigger mode.
■SAVE/RECALL: Press to display the Save/Recall menu. You can use the Save/Recall
menu to save and recall up to 20 oscilloscope setups or waveforms in internal memory
(up to 20 waveforms) or on a USB memory device (limited by memory capacity of USB
device). You can also use it to recall the default factory settings, to save waveform data
as a comma-delimited file (.CSV), and to save or print the displayed waveform image.
■ACQUIRE: Press to display Acquire menu. You can use the Acquire menu to set the
acquisition Sampling Mode (Sampling, Peak Detect, Average).
■MEASURE: Press to display a menu of measurement parameters.
■CURSORS: Display the Cursor Menu. Vertical Position controls adjust cursor position
while displaying the Cursor Menu and the cursors are activated. Cursors remain
displayed (unless the “Type” option is set to “Off”) after leaving the Cursor Menu but
are not adjustable.
■DISPLAY: Press to open the Display menu. You can use the Display menu to set grid
and waveform display styles, and persistence.
■UTILITY: Press to open the Utility menu. You can use the Utility menu to configure
oscilloscope features, such as sound, language, counter, etc. You can also view
system status and update software.
■DEFAULT SETUP: Press to reset the oscilloscope’s settings to the default
factory configuration.

You can use the Universal knob with many functions, such as adjusting the holdoff
time, moving cursors, setting the pulse width, Setting the Video Linage, adjusting
the upper and lower frequency limit, adjust X and Y masks when using the pass/fail
function etc. You can also turn the “Universal” knob to adjust the storage position of
setups, waveforms, pictures when saving/recalling and to select menu options.

DC passes both AC and DC components of
the input signal.
AC blocks the DC component of the input
signal and attenuates signals below 10 Hz.
GND disconnects the input signal.

Limits the bandwidth to reduce display noise;
filters the signal to reduce noise and other
unwanted high frequency components.
