1.20 SAFETY
The maximum voltage limit for the analog probe in 1x mode is -8v / +13v, and the maximum
voltage limit in 10x mode is -40V / +40V. The maximum voltage limit for the digital channels
is -.0.5v to +7v. Oscium is not held liable for usage outside of these limits.
1.30 Compatibility
1.31 Hardware
Oscium has two versions of the same hardware with the only difference being the connector:
iMSO-204, which has a 30-pin connector & iMSO-204L, which has a lightning connector. Here
are the specific Apple devices that are compatible with each piece of our hardware:
iMS0-204L (Lighting Version) iMSO-204 (30-pin version)
iPod touch (5th generation) iPod touch (4th generation)
iPhone 5S, iPhone 5C, iPhone 5 iPhone 4s, iPhone 4, iPhone 3GS
iPad (4th generation), iPad Mini iPad (3rd generation) iPad 2, iPad
*With an Apple-approved lightning adapter, iMSO-204 will also work with the newer, lightning
models. But the same is not true in reverse. The lightning adapter will not enable iMSO-204L
to work with 30-pin iOS devices.
1.32 Software
Although Oscium has two versions of hardware (iMSO-204 & iMSO-204L), there is only
one app and it is called iMSO2. iMSO2 is free to download in the App Store. Upon plugging
our hardware into your iOS device, the downloaded app will recognize which version of the
hardware is in use. The app functions exactly the same regardless of which hardware is in use.
Please keep in mind that the:
Required OS is 5.0 or newer
Oscium also has another app called iMSO. This app only works with iMSO-104 hardware. For
iMSO-204 & iMSO-204L to work, please download iMSO2.

cursors, two lines will appear. One is dotted and the other is solid. The solid line is active and
can be moved by touching the line and while holding that line moving it either up or down.
While in tracking mode both the solid and dotted lines will move together. In independent
mode the solid line is the only line that can be moved. Additionally, dynamic metrics related
to the solid line are available in the summary screen located at the bottom (and in the color of
the selected channel). Tap on the dotted line and it will become a movable solid line, while the
other line will change to dotted.

bar. The voltage level at the point where the selected cursor crosses the waveform is indicated
in the summary bar next to @V and the vertical difference between the crossing points of the
two vertical cursors is indicated in the summary bar next to ∆V. When using vertical cursors
with the analog channel both @t, t and @V, V will be visible in the summary bar.
Verify that cursors are selected. To move cursors independently of one another,
touch .To move cursors as a single unit with a fixed distance between them, touch

Time settings available in the Base option include: . The option sets the unit of
measure in seconds. The option sets the unit of measure in hertz.
2. If cursor metrics are to be displayed in Phase, touch . The options next to the phrase
360° WITHIN sets the phase. The option of sets 360° within 5 divisions. The option
sets 360° between the two cursors.
3. If cursor data is to be displayed as a ratio, touch . The options next to the phrase 100%
WITHIN set the ratio. Ratio settings available next to 100% WITHIN include: . The
option of sets 100% within 5 divisions. Since there are 10 divisions in the horizontal time
scale, this option effectively cuts the screen in half. The option sets 100% between the two
cursors.

CH B. To change the trigger from CH A to CH B, touch .Then touch . Then simply
select the SOURCE to be triggered.
To change the voltage level, simply touch and drag the bubble either up or down. Moving the
level up will increase the voltage level and moving it down will decrease the voltage level. The
exact voltage level will appear just to the left of the bubble along with either an up arrow or a
down arrow. An up arrow indicates that the trigger is on a rising edge; a down arrow indicates
that the trigger is on a falling edge. It is also possible to change the trigger level in the
advanced triggering menu. Tap .Then tap and, when active, it will change to .
To navigate to an exact trigger level touch on next to the word LEVEL. The analog
trigger level pick wheel should then appear.

3.10 Product Warranty
iMSO-204 & iMSO-204L hardware both come with a full one year manufacturer’s warranty.
No warranty exists on probes and accessories.
3.20 Accessories
iMSO-204 and iMSO-204L come with the following accessories: 1x / 10x analog probe, logic
harness, five SMD grabbers, and one screwdriver.
3.21 1x / 10x Analog Probes
The analog probe is capable of measuring signals up to 100 MHz (although our fastest
scope is currently limited to 50 MSPS). This probe can operate in either 1x or 10x mode. It is
removable with an SMB connector.
3.22 Logic Harness
The logic harness is has five colors: purple (D1), yellow (D2), blue (D3), orange (D4), and black
(ground). The colors on the harness match up with the colors on the interface. If a user is
color blind, the harness colors are labeled D1, D2, D3, D4, and GND on the back of the iMSO-
204/iMSO-204L hardware
3.23 SMD Grabbers
SMD grabbers have the Oscium flame custom built into the front.
3.24 Screwdrivers
The electrically-isolated flathead screwdriver is custom made for iMSO-204 and iMSO-204L
and is used for compensating the device.
