Siglent SDS-5000X-SENT SENT trigger & decode (software)
Siglent SDS-5000X-SENT to activate SENT (SAE J2716) trigger and decode for automotive sensors. For the SDS5000X.
SDS-5000X-SENT — SENT trigger & decode
SENT (SAE J2716) trigger and decode for automotive sensors.
Supplied as a licence key issued against the instrument's serial number. There is no hardware to fit and nothing to return: the code is entered in the instrument's own menu and the function is available immediately, on the instrument you already own.
What this option does
What it does
Triggers on the start of a message, the slow channel, the fast channel or an error, and decodes SENT from the analogue channels or the SPL2016’s digital channels.
What you use it for
SENT carries its data in the time between edges, so decoding depends on measuring those intervals accurately — which is exactly what an oscilloscope does well.
In practice
A pressure sensor reports plausible but wrong values when the engine bay is hot. Triggering on errors and decoding the messages shows where the readings go wrong, alongside the raw edge timing that explains why.
Trigger and decode details
From the SDS5000X data sheet.
| Trigger types | Start, Slow channel, Fast channel, Error |
| Decode from | Analogue channels C1–C4 or SPL2016 digital channels D0–D15 |
| Decoders at once | 2, full duplex |
| Standard on every SDS5000X | I²C, SPI, UART, CAN, LIN — no key needed |
Compatibility
The option runs on every SDS5000X model, at every bandwidth. It is newer than Siglent’s 2019 data sheet, so an instrument from that period needs current firmware first.
| Channels | 350 MHz | 500 MHz | 1 GHz |
|---|---|---|---|
| 4-channel | Compatible | Compatible | Compatible |
| 2-channel | SDS5032X (no longer made) With current firmware | SDS5052X (no longer made) With current firmware | SDS5102X (no longer made) With current firmware |
The 2-channel SDS5032X, SDS5052X and SDS5102X are no longer made; their keys remain available. The SDS5000X HD is a different series with its own option keys.

Questions about SDS-5000X-SENT
Can I decode from the SPL2016 logic probe?
Yes. SENT decodes from the analogue channels or from the SPL2016’s 16 digital channels.
Does it work on an older SDS5000X?
Siglent’s 2019 data sheet does not list SENT, so an instrument from that period needs current firmware before the key can be used. Send us the serial number and we will confirm before you order.
Which protocols are already included?
I²C, SPI, UART, CAN and LIN trigger and decode are standard on every SDS5000X. CAN FD, FlexRay, I²S, MIL-STD-1553B and SENT are trigger-and-decode keys; CAN XL, Manchester, ARINC 429 and SpaceWire are decode-only keys. Two decoders run at the same time.
How is the licence delivered?
Supplied as a licence key issued against the instrument's serial number. There is no hardware to fit and nothing to return: the code is entered in the instrument's own menu and the function is available immediately, on the instrument you already own. Add the instrument’s serial number to your order, or send it to us afterwards — the key is issued against it.
Can I return a licence?
Software licences and activation keys are delivered electronically and are excluded from the 14-day EU return right once the key has been issued. If you are unsure which key you need, ask us first — with your serial number we can confirm it.
Not sure this is the right key?
Send us your serial number and what you want to measure. We will confirm the exact option before you order.
