SDS-5000X-I2S I2S trigger & decode option license
Siglent SDS-5000X-I2S I2S is a I²S audio trigger and decode, including left- and right-justified formats for the SDS5000X.
SDS-5000X-I2S — I²S audio trigger & decode
I²S audio trigger and decode, including left- and right-justified formats.
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
Decodes I²S from bit clock, word select and data, in the standard, left-justified and right-justified variants, with 0 to 31 start bits and 1 to 32 data bits. Triggers on data, mute, clip, glitch, or a rising or falling edge. Works from the analogue channels or the SPL2016’s digital channels.
What you use it for
Audio faults are usually in the data, not the electrical signal — a swapped channel, a word-length mismatch or a clipped sample looks healthy on an undecoded trace.
In practice
A product clips on one channel at high volume. Triggering on clip captures the offending samples directly, instead of scrolling through seconds of healthy audio to find them.

Questions about SDS-5000X-I2S
Can I decode from the SPL2016 logic probe?
Yes. I²S decodes from the analogue channels or from the SPL2016’s 16 digital channels.
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.
