Brief Introduction
The IDSO is WLAN dual-channel digital storage oscilloscope geared towards tablet computers, it's
a small, lightweight, portable, battery powered, fully featured two channel oscilloscope. The
oscilloscopes is ideal for production test, research and design and all of the applications involving
analog circuits test and troubleshooting, as well as education and training.
Instead of a built-in screen it uses your tablet iOS, Android or PC (Windows) to display the
measurements. Data exchange between the tablet and the oscilloscope is via WLAN, there are no
cables. Also, as there is no physical connection between the oscilloscope and the tablet, it is a
very safe instrument to use. Due to the wireless principle, the oscilloscope and the ‘screen’ do not
need to be at the same location.
The communication protocol between the oscilloscope and the tablet is freely available, so it is
easy for third-party developers to develop applications for other purposes. Finally, it is equipped
with a USB port for charging of the internal battery. If desired, it can also connect to a PC via the
USB port, instead of wireless.

2.9 Set Trigger System
2.9.1 Trigger Setting
Click “Setup-> Trigger” menu.
The following figure shows the trigger system control.
Trigger Setting
The trigger determines when the oscilloscope starts to acquire data and display a waveform.
When a trigger is set up properly, it can convert unstable displays or blank screens into meaningful
waveforms.
If the oscilloscope wants to acquire a waveform, it collects enough data so that it can draw the
waveform to the left of the trigger point. The oscilloscope continues to acquire data while waiting
for the trigger condition to occur. The oscilloscope continues to acquire enough data so that it can
draw the waveform to the right of the trigger point after it detects a trigger.
The Edge trigger determines whether the scope finds the trigger point on the rising or the falling
edge of the signal. Select Edge trigger mode to trigger on Rising edge or Falling edge.
Trigger Mode: Edge.
Trigger Sweep: Set the sweep mode to Auto, Normal or Single.
Auto: Performs the acquisition freely in absence of valid trigger. It allows the generation of
untriggered waveforms.
Normal: Updates the displayed waveforms only when the oscilloscope detects a valid trigger
condition. Before this update, the oscilloscope still displays the old waveforms. This mode
shall be used when you want to only view the effectively triggered waveforms. In this mode,
the oscilloscope displays waveforms only after the first trigger.
Single: Acquire waveform when trigger occurred, then stop to acquire.
PC Application
User’s Manual 29
Trigger Source: You can use the trigger source options to select the signal that the oscilloscope
uses as a trigger. Select the trigger source signal (CH1, CH2 or EXT).
Trigger Slope: Set the slope to Rising (+) or Falling (-).
Rising: Trigger on rising edge
Falling: Trigger on falling edge
Also user can also set trigger parameters in the bottom right sidebar.
Change Trigger Level
Trigger Level icon: User can also drag the trigger icon on screen to adjust the trigger
level. Double click trigger icon to set trigger level to the vertical midpoint between the peaks of the
trigger signal.
2.9.2 Capturing a Single-Shot Signal
To capture a single event, it needs to gather some pre-test knowledge of the signal in order to set
up the trigger level and slope correctly. For example, if the event is derived from 3.3V COMS logic,
a trigger level of 1.2 or higher Volts should work on a rising edge.
Do these steps as follows:
1. Set the probe and the channel attenuations to “x10”.
2. Set up the trigger in the Trigger Menu, or in the Trigger Setting window.
(1) Adjust the Trigger Mode to Edge.
(2) Set the Trigger Sweep to Single.
(3) Set the Trigger Source to CH1.
(4) Set the Trigger Slope to “+” which means you select the rising edge.
(5) Adjust the Volt/Div and the time base in a proper range for the signal.
(6) Drag the trigger level sign on the waveform display screen to proper position. It ally higher a
little above the normal level.
(7) Click START button to start capturing. When the trigger conditions are met, data appears on
the display representing the data points that the oscilloscope obtained with one acquisition.
This function helps to capture the signal occurrence easily, such as the noise with large amplitude;
set the trigger level higher a little above the normal level and press and wait. When noise occurs,
the instrument will record the waveform before and after the trigger.
