Siglent SSG3000X-IQE PLUS-21BW32 Upgrade an SSG3021x-IQE PLUS to 3.2 ghz (software licence)
Siglent SSG3000X-IQE Plus-21BW32: software key that upgrades an SSG3021X-IQE Plus from 2.1 GHz to 3.2 GHz in CW and external-IQ mode.
SSG3000X-IQE Plus-21BW32 — upgrade an SSG3021X-IQE Plus to 3.2 GHz
A software key that raises an SSG3021X-IQE Plus from 2.1 GHz to 3.2 GHz — in CW and in external-IQ mode.
After activation the generator covers 9 kHz to 3.2 GHz in CW and 10 MHz to 3.2 GHz in IQ mode: the range of the SSG3032X-IQE Plus. Vector-modulated signals from an SDG6000X baseband can then be placed in the 2.4 GHz band and above, with the same 200 MHz RF modulation bandwidth.
As with the non-IQ key, it is the route for a requirement that arrives later. Bought new, the SSG3032X-IQE Plus is the cheaper way to 3.2 GHz — see the comparison below.

What the key adds
CW 9 kHz to 3.2 GHz
The full CW range of the SSG3032X-IQE Plus.
IQ mode 10 MHz to 3.2 GHz
External I/Q modulation across the extended band; EVM ≤ 1.2 % (16QAM, nom.) from 1.5 to 3.2 GHz.
Software only
Issued against the serial number; no hardware change, no recalibration.
Any time after purchase
The upgrade path for when the project moves up in frequency.
Which instrument it is for
For the SSG3021X Plus (no IQ) use the SSG3000X Plus-21BW32 key instead; the 3.2 GHz models need no key.
This key is for the SSG3021X-IQE Plus. The non-IQ model takes the SSG3000X Plus-21BW32, and the earlier SSG3021X-IQE (without Plus) takes the SSG3000X-IQE-21BW32. The codes are not interchangeable.
Upgrading later costs more than buying 3.2 GHz now
| SSG3021X-IQE Plus + this key | €4,299 + €1,999 = €6,298 |
| SSG3032X-IQE Plus bought outright | €5,699 |
| Difference | €599 more via the upgrade |
Prices ex VAT. The key exists for a requirement that changes after the purchase, not as a way to spread the cost.

| Delivery | Licence key for the instrument’s serial number |
From the SSG3000X Plus data sheet EN01A and Siglent’s price list.
How it is delivered
1 · Send us the serial number
A software key is generated for one instrument. Add the serial number to the order, or mail it afterwards.
2 · Receive the key
The licence key is delivered by e-mail — nothing is shipped and nothing leaves your bench.
3 · Enter it on the instrument
Enter the key in the generator’s option menu; the function is available immediately and stays with that unit.
Questions about the SSG3000X-IQE Plus-21BW32
Is it cheaper to buy the 2.1 GHz IQE model and upgrade?
No. SSG3021X-IQE Plus plus this key comes to €6,298; the SSG3032X-IQE Plus costs €5,699 — €599 less. The key is for when the need arrives after the purchase.
Does it extend the IQ mode as well?
Yes — CW to 3.2 GHz and IQ mode from 10 MHz to 3.2 GHz, as on the SSG3032X-IQE Plus.
Does the hardware change?
No. It is a software key; the instrument keeps its calibration.
Can this key add IQ to a non-IQE model?
No. The external I/Q interface is hardware and cannot be added later; this key only raises the frequency range of a model that already has it.
What do you need from me?
The serial number of the instrument. The key is generated for that unit only.
Not sure which key your generator takes?
Send us the model name and serial number. We will confirm the right order code — Plus or not, IQE or not — before anything is ordered.
