The DP-201A can shift the phase angle from 0 to 359 degrees in 1-degree steps by inputting orthogonal coordinate signals in digital data. It has a built-in trigonometric function ROM, allowing it to output analog signals in real-time. The setting of the rotation angle data can also use a Samir switch, with the option to select either positive logic or negative logic TTL levels. ■ The phase angle Θ obtained from the X-Y coordinate output voltages EX and EY can be rotated from 0 to 359 degrees. ■ The setting resolution is in 1-degree steps. ■ It can be set with 10-bit digital data. ■ Due to its analog-digital mixed circuit, high-speed phase rotation is possible. ■ By connecting our two-phase oscillator, variable phase output can be obtained.
