Siglent SDS5000HD-SpaceWire SpaceWire decode (software)
Siglent SDS5000HD-SpaceWire is a SpaceWire decode from 2 to 400 Mbps, as characters or packets — decode only. For the SDS5000X HD. ( license option )
SDS5000HD-SpaceWire — SpaceWire decode (no trigger)
SpaceWire decode from 2 to 400 Mbps, as characters or packets — decode only.
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 SpaceWire from the Data and Strobe lines at 2, 5, 10, 20, 50, 100, 200 or 400 Mbps or a custom rate, with fixed-speed or automatic clock recovery, automatic, NULL, pattern or manual synchronisation, and a character (N/L-char) or packet view. It is a decoder only and reads the analogue channels.
What you use it for
SpaceWire links the instruments, memories and processors of spacecraft data-handling systems. There is no clock line to look at; the decoder does the data-strobe recovery and shows what the link is carrying.
In practice
A new instrument unit will not establish its link. Decoding the start-up shows whether the two ends get as far as exchanging NULLs, and in the packet view where the traffic stops once they do.
⚠ Decode only — the SDS5000X HD has no SpaceWire trigger. Decoding uses analogue channels C1 to C4, not the SPL2016’s digital channels.
Trigger and decode details
Siglent added this decoder to the SDS5000X HD after data sheet EN01A; the figures are those Siglent publish for the same decoder on the SDS3000X HD and SDS6000L, and the price list 2026_4 lists the key.

Questions about SDS5000HD-SpaceWire
Can I trigger on SpaceWire data?
No. On the SDS5000X HD SpaceWire is decode only. Capture with an edge, pulse-width or pattern trigger, and the decoder reads what was captured.
Can I decode from the SPL2016 logic probe?
No. SpaceWire decodes from the analogue channels C1 to C8 only.
Which protocols are already included?
I²C, SPI, UART, CAN and LIN trigger and decode are standard on every SDS5000X HD. CAN FD, FlexRay, I²S, MIL-STD-1553B, SENT, ARINC 429, Manchester, CAN XL, SpaceWire and SPMI are keys. Up to 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.
