License upgrades for Berkeley Nucleonics arbitrary waveform generators (Models 670C, 675, 685C, 685, and 686) require the unit to be sent to our facility, as recalibration may be necessary after the software is applied. Typical turnaround time is 1 to 2 weeks from the date we receive the instrument. To minimize downtime, contact Berkeley Nucleonics in advance to schedule your upgrade and confirm parts availability. License options include bandwidth upgrades, channel additions, sample rate increases, and feature additions such as the -PAT Serial Pattern Generator.
