The V340 provides eight independent DDS-synthesized waveform outputs, each programmable for frequency and amplitude. Any output may be switched to a front-panel test connector, allowing in-crate calibration check without removing field cables.

Optional software-switchable transformers are available with 1:1 or 5:1 ratios, providing isolated outputs to 100 volts peak-to-peak. Built-In-Self-Test is optional.
