Analyser upgrades

Firmware upgrades for handheld analyser models SDA-02 and SDA-01
Our handheld serial data analysers have the ability to be upgraded with new operational features after they have been sold. This is achieved by means of “firmware upgrades”, released by New Forest Electronics every few months.

Wherever possible, the latest features added to the analyser are made available for earlier models. For instance, timestamping can be added to any model handheld analyser, including the original SDA-01.

Sometimes particular features cannot be added, because the earlier models do not have enough program memory or appropriate circuitry. Please see the table below, or contact us to confirm what is possible.

(For details of the latest firmware upgrade, click here, and use your browser back button to return)

The standard procedure is to return your analyser to us, and we will fit the upgrade and carry out a functional test. Turn around is usually one working day, and the UK cost is £49 plus £8 for next day return delivery. (An upgrade is free for analysers bought within the last 12 months).

Alternatively, for overseas customers with basic technical resources, we can ship the firmware component with fitting instructions. This saves the analyser having to be returned to the UK.
