ScanaQuad (SQ25) 4 channel logic analyzer

ScanaQuad (SQ) is a series of high performance 4 channels logic analyzers and digital pattern generators. They are designed to be your best companion when working on serial protocols like UART, SPI, I2C, 1-Wire, USB, I2S, CAN, LIN, RS232, RS485, and more. With ScanaQuad Logic Analyzers, you can capture signals, you can play them back, and you can even build genuine test signals and generate them!

Being able to capture and generate logic patterns simultaneously with the same tool, is extremely useful when debugging Logic signals, and it only comes with ScanaQuad.

Comes complete with a set of probes and a USB cable.


  • Enhanced ±12V input protection
  • 25 MSPS @ 4 channels>
  • 256K points / channel
  • Trigger: Rising, falling, level, pulse width
  • 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).
  • Huge improvements have been made on the signal generator end:
  • Precise control over loop point or ability to generate arbitrary signals on any number of channels while recording the result on the others.
  • ScanaQuad input/output stage is fully protected while offering flexible options like Open Drain outputs and configurable pull up/down resistors.
  • The digital signal generator has an output voltage of 3.3V.
  • ScanaQuad was designed to be the ultimate 4 channels logic analyzer and signal generator on the market.

Protocols Supported

1-Wire Protocol Decoder. This is a standard 1-Wire bus decoder. It will detect and display the device family
as well as commands and different bus states. This decoder will differentiate between
regular and overdrive modes and warn you in case of irregularities.
1-Wire Temperature Sensors decoder. Supported sensors: DS1820, DS18B20, DS18S20, DS1822, DS1825, DS1920, DS2438, DS2760, DS28EA00, MAX31820, MAX31826 and MAX318(50/51).
CAN Protocol Decoder. This a standard can bus decoder that will interpret and display normal and extended
CAN frames. It will also display stuffed bits, calculate checksum and compare it against the one given in the frame.
DHT11 / DHT22 Protocol Decoder. A very simple protocol for the temperature humidity sensor. DHTxx generates 2 bytes
for humidity and 2 bytes for temperature. Data is stored in 10th deg and %.
DMX-512 Protocol Decoder. A standart decoder of unidirectional DMX-512 differential interface commonly used to control stage lighting and effects.
I2C Protocol Decoder. A standard decoder of Phillips (NXP) multi-master serial single-ended computer bus.
JTAG JTAG Protcol Decoder
LCD (4-bit mode) Decoder. This decoder script will interpret control and display signals sent to a standard
Hitachi HD44780 based LCD device
LIN Protocol Decoder. This is a standard Local Interconnect Network bus decoder supporting 1.x and 2.x
protocol versions
Manchester Coding (Phase Encoding) Decoder. Widely used signal encoding technique wich ensures frequent line voltage transitions, directly proportional to the clock rate
Maple Bus Maple Bus Protocol Decoder.
MIDI MIDI (Musical Instrument Digital Interface) Protocol Decoder.
NMEA 0183 Protocol Decoder. A standard decoder of National Marine Electronics Association Protocol for communication between marine electronic devices such as echo sounder,
sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of instruments.
Parallel Bus Generic Parallel Bus Decoder.
This decoder script will interpret 1 to 8 data lines as a 1 byte bus.
PWM Decoder. A decoder of pulse-width modulation, or pulse-duration modulation signal.
SPI Protocol Decoder.
Highly configurable SPI bus decoder.
WIZnet W5100 SPI decoder/debugger. Decodes SPI traffic on the SPI bus between an MCU and the WIZnet W5100 Ethernet.
It decodes raw bytes to human-readable OP-Codes, registers, TX-memory and RX-memory
addresses in the PacketViewer.
UART Serial UART (Universal asynchronous receiver/transmitter) Protocol Decoder.
USB 1.1 USB 1.1 Protcol Decoder

ScanaStudio Software

As you can see on the screen capture above, ScanaStudio’s interface is divided into different sections. Each one of those sections is given a number in the image above, and is described in the paragraph below:

  1. Waveform area: This rectangle shows the actual logic signals and allows zooming and panning via simple mouse clicks.
  2. Side Panel: This is where different configuration panels appear. For instance, device or decoders configuration panels appear in this zone.
  3. Top toolbar menu: This menu hosts buttons for the most common actions that a user can take to capture signals, measure it and analyze it.
  4. Device status: This section displays the status of the device (the one attached to this workspace) as well as the progress of an operation (if an operation is underway, like capturing some signals, or parsing some data).
  5. Hint box: This part is used to show some hints according to what the mouse is pointing at.
  6. Cursor time: The zone always shows the exact time under the mouse cursor.
