Unlock more from your instrument

Software licenses and upgrade options let you add capability without buying new hardware — extend bandwidth, add serial-bus trigger & decode, power and signal analysis, MSO digital channels, an arbitrary generator and more. Pick your instrument series below.

Most options are license keys — enter the code and the feature unlocks, no return needed.
Upgrade any time
Buy what you need now and add bandwidth, decoders or analysis later as your work grows.
Hardware where needed
A few options (MSO, some bandwidth) include a logic probe or hardware — these are noted per item.

Frequently asked questions

Siglent license keys & upgrade options.

How does a license key work?

Most options are software licenses tied to your instrument's serial number. You receive a key, enter it in the instrument's menu, and the feature unlocks immediately — no need to return the unit.

What can I unlock?

Depending on the instrument: bandwidth upgrades, serial-bus trigger & decode (I²C/SPI/UART, CAN/CAN FD, LIN, FlexRay, 1553B, SENT, Manchester, I²S…), power and signal analysis, MSO digital channels, an arbitrary waveform generator, EMI/real-time/modulation analysis, and frequency or I/Q upgrades on RF generators.

Do any options need hardware?

Most are pure software, but a few — such as MSO (which needs a logic probe) — include hardware. These are clearly marked on each instrument's options page.

My instrument isn't listed — can it still be upgraded?

Very likely. We're adding option pages for more series (including the latest HD scopes and RF generators). Contact us with your model and we'll confirm the available licenses and price.

How do I order a license?

Open your instrument's options page, choose the license you need, and order it — or request a quote and we'll handle it, including for multiple units.

Are prices shown including VAT?

Prices on the option pages are per license. For current pricing, availability and any volume discounts, see the individual option or contact us for a formal quote.
