SP259 Series User Manual SP259 / SP259i
SP259 Series overview
SP259 series logic analyzers and protocol decoders oer in depth analysis of logic signals and protocols
with 250MHz (4ns) timing resolution. 9-channel operation allows 8-bit parallel data to be captured
along with a clock or strobe signal. SP259 series logic analyzers connect to a computer via a USB3
interface to configure the device and to visualize captured data.
SP259 Series is composed of two devices, SP259 and SP259i. Both oer 9 logic inputs, but
SP259i integrates industrial receivers for CAN, LIN, RS232 and RS485 buses.1

Embedded memory
SP259 series logic analyzers feature a 1Gb HyperRAM memory running at 4Gbps and is used to store
compressed samples before streaming to host computer. This embedded memory ensures uninter-
rupted captures of high frequency signals for long period of time without needing any reliance on host
computer performances.
1Industrial receivers in the SP259i are multiplexed with one or more of the existing 9 logic channels

SP259 Series User Manual SP259 / SP259i
Principle of operation
SP259 Series logic analyzers connects to a computer via a USB cable. A free soware - called ScanaStu-
dio - is used to configure the device and display captured signals. The soware can also be used to
further analyze the captured samples by decoding protocols like I2C, SPI or UART.
Embedded memory vs streaming
USB based logic analyzers (ones that don’t have a display and rely on a computer for that matter)
usually operate according to one of two schemes:
• Using an embedded memory to store captured samples. Samples are later downloaded at a
slower speed via the USB interface. This has the advantage of not being limited by USB transfer
rate, but has the disadvantage of limited embedded memory.
•Streaming
captured samples over the USB connection, at the maximum possible speed. While
this oers the advantage of a virtually unlimited memory (only limited by host computer’s
memory), it has the disadvantage of limiting the sampling rate to USB’s throughput.
SP259 combines the advantages of both streaming and embedded memory techniques. An embedded
1Gb HyperRAM memory stores captured and compressed samples at 250 MHz sampling rate on all
channels, while a USB interface transfers the data simultaneously, eectively emptying the embedded
memory and making more room for new samples. This results is a logic analyzer that can capture
dozens of minutes of logic signals activity on 9 channels at 250 MSPS.
Versatile trigger system
SP259 series oer a state of the art trigger system. It’s composed of two FlexiTrig ® trigger engines, each
FlexiTrig engine can be used in one of those modes:
•Edge trigger
•Pulse trigger (with minimum and maximum pulse width)
•Timed logic sequence
•Protocol based trigger (e.g. I2C bus address or serial UART character)
•External trigger source
Furthermore, the two trigger engines (called A and B hereaer) can be cascaded in one of the following
modes:
•A then B (Wait until A triggers then arm B trigger engine)
•B then A
•A and B (Trigger engines A and B must trigger, but in any order)
(c) Ikalogic SAS 2023 12/26

SP259 Series User Manual SP259 / SP259i
•A or B (whoever triggers first)
Finally, an external trigger output is always active, in all modes and generates a trigger pulse whenever
a trigger condition is met and a capture starts. Signal specifications for External trigger input and
output are detailed in the following section.
Flexitrig®timing performances
Flexitrig®oer the following timing performances:
•Edge or Logic level trigger: Maximum signal frequency is 62.5MHz
•Protocol based trigger or Timed logic sequences: Maximum signal frequency is 25MHz
External trigger OUT specifications
Figure 6: External trigger OUT timings
There is an internal data path delay of 20ns before external signals reach internal trigger engine (T0).
When trigger event occurs, 10ms (T2) pulse is generated on the Trig Out port. This port has a 50 Ω series
impedance allowing easy interfacing to 50 Ω input devices. This can be used to synchronise the capture
with other equipment like an oscilloscope. Polarity of the trigger can be set in soware. There is also a
(c) Ikalogic SAS 2023 13/26

SP259 Series User Manual SP259 / SP259i
10 ns delay (T1) between internal trigger detection and Trig Out assertion. Therefore, the total time for
an external event to generate a Trigger OUT pulse is T0+T1 = 30ns.
External trigger IN specifications
Figure 7: External trigger IN timings
The Trig In port allows to start acquisition on an external event generated by another instrument. The
minimum pulse width (T1) is 8ns. Polarity can be set in soware. The input impedance is also soware
selectable (100k Ωor 50 Ω). The threshold level is 0.4V. T2, the time between external trigger in active
edge and internal trigger engine assertion is 20ns.
Industrial port (SP259i only)
SP259i oer the possibility to connect directly to industrial buses, as opposed to logic channels which
can only be connected to single ended logic level such as LVCMOS or LVTTL. Each one of the industrial
inputs integrates a dedicated receiver circuit, perfectly adapted to each standard. For more reliability
in an industrial context, each bus receiver is exposed via screw terminals. Adequate wires (6-30 AWG)
should be used to connect SP259i to the bus being probed
4
. Industrial receivers oer the advantage of
visualizing exactly what a standard o-the-shelf transceiver would receive if connected to that bus.
The list of the industrial inputs is detailed below:
4Wires to connect SP259i to industrial buses are not provided.

SP259 Series User Manual SP259 / SP259i
Once the soware is installed, run it, and create a new workspace by selecting “SP259” or “SP259i” as
the device type.
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 is USB3 compatible and can deliver at least 250mA.
•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 SP259(i) workspace.
3. Connect the probes to SP259(i) and to your signals source
4. Ensure the ground probe is connected
5. Check if the status LED is blinking: if it’s the case, it means the some logic changes are already
being detected on the probes.
6. Hit the start button in ScanaStudio and wait until signals are captured.
You can adjust the capture duration by adjusting the number of samples in the device configuration
tab.
