Purchase Daqarta

Pay once...License includes all future versions.

Daqarta was developed for professional and academic research applications, with the intent that it should be easily affordable to even the smallest lab or company. But there are many uses for Daqarta outside the lab, so Daqarta offers separate Professional and Personal / Hobby licenses.

You may evaluate all features of Daqarta FREE for 30 sessions or 30 days without charge. After that, sound card signal input and Professional features (multi-trace memory arrays, macro file saves, remote control by your own software, and Spectrum Limits testing ) are disabled unless you purchase a license. All other features continue to operate normally. If you don't need signal inputs or Pro features, Daqarta can still be used for signal generation and file analysis without any time limits.

After clicking one of the Buy Now buttons below, you will be taken to a secure purchase page. You may pay with a PayPal account or a credit card. To use a credit card, click "Pay with Debit or Credit Card" on the purchase page, which will take you to a "Pay as Guest" page... you do not need to open a PayPal account.

Please include the full name, business/institution name, and street address, plus a valid E-mail address for the end user, if different from the purchaser. This information will never be released, or used for any purpose other than to notify users of new Daqarta versions via E-mail (unless you specifically decline), or to validate requests for replacement of lost keys.

Licensed users will be sent a small encrypted text file via Email, which can be converted to the actual license key by means of the Install Daqarta License Key option in the File menu. Please allow up to 24 hours for Email key delivery.

Note: If your Email system uses a "whitelist", please make sure it will accept mail from the daqarta.com domain. Otherwise, if you don't receive your key, check your spam folder.

License keys will work with future Daqarta versions; you only need to pay once.
