SQ Series overview

SQ devices are a series of 4 channels logic analyzers and digital pattern generators. They have an
integrated memory (up to 4M points per channel) and a high speed USB interface to transfer signals
from/to the host computer. A free application (ScanaStudio) is provided to analyze captured signals or
create patterns to be generated. Generated signals may be arbitrarily created signals, or alternatively,
user may play back previously captured signals

Figure 1: SQ Series logic analyzer devices (From le to right: SQ200, SQ100, SQ50, SQ25)

SQ devices oer an intuitive way of analyzing logic signals, backed with exciting features like enhanced

±

35V input protection, adjustable input threshold, direct connection to RS232/485, CAN and LIN buses,
ability to trigger on specific protocols (like a UART word or an I2C address). The signal generator was
designed to be very versatile: Precise control over loop point can be achieved as well as the ability
to generate arbitrary signals on any number of channels while recording the result on the others. SQ
series’ input/output stage is fully protected while oering flexible options like Open Drain outputs
and configurable pull up/down resistors. Furthermore, the digital signal generator has an adjustable
output voltage from 1.8V to 5V, which covers most TTL, CMOS and LVCMOS applications.

SQ Series is composed of four devices: SQ25, SQ50, SQ100 and SQ200. All have 4 channels that

can be used to capture and/or generate logic signals.

Typical applications

By combining logic analyzer and pattern generator capabilities in a single low price device, SQ is a
perfect solution for students and small design houses. For more channels and more performances,
check SP series logic analyzers.

• Embedded systems

• Firmware development and debugging

• Educational work

• Serial protocols analysis, like I2C, SPI, UART or 1-Wire (non exhaustive list)

• Reverse engineering

Principle of operation

ScanaQuad is also able togenerate captured signals (play back), or build genuine arbitrary test patterns,
like UART, SPI or I2C packets. It can also be used to compose and generate Frequency modulation
(FM) signals and pulse width modulation (PWM) signals. Thanks to the mixed mode, SQ devices can
even capture and generate digital signals simultaneously. Mixed mode is specifically designed to allow
engineers to stimulate a circuit with test signals and capture its response.

Embedded memory

SQ series logic analyzers come with an embedded memory to store captured samples, as well as the
patterns to be generated. Hence, SQ devices do not live-stream captured signals over USB. This has
one big advantage: the performance do not depend on the host computer USB port performance

Versatile trigger system

SQ series oer a state of the art trigger system. It’s composed of one FlexiTrig®trigger engines, each
FlexiTrig engine can be used in one of those modes:

• Edge trigger

• Pulse trigger (with minimum and maximum pulse width)

(c) Ikalogic SAS 2019 10

SQ Series User Manual SQ25/SQ50/SQ100/SQ200

• Timed logic sequence

• Protocol based trigger (e.g. I2C bus address or serial UART character)

Finally, an external trigger input and output is available via an accessory called TrigBox.

What’s in the box

SQ series is shipped with the following items:

1. SQ device

aer the soware and drivers have been installed.

Once the soware is installed, run it, and create a new workspace by selecting the model that match
your SQ device from the list of possible choices.

Note

: if at the point the device is not recognized by your computer, the ScanaStudio workspace
is created as a demo workspace or the status LEDs stays orange even aer creating a ScanaStudio
workspace, please follow these steps:

• Ensure the USB port used can deliver at least 500mA.

• Try switching to another machine if one is available.

• If all of the above fails, please contact Ikalogic support.

Capturing your first signal

To capture your first logic signals, please follow these steps:

1. Connect the device via USB

2. Launch ScanaStudio and create an SQ compatible workspace.

3. Connect the probes to SQ device and to your signals source

4. Ensure the ground probe is connected correctly

5.

Hit the start button in ScanaStudio and wait until signals are captured and displayed on the
screen.

You can adjust the capture duration by adjusting the number of samples in the device configuration
tab.
