Arrangement for positioning a pen in a recording device |
摘要 |
The present invention is embodied as an arrangement for positioning a pen in a device that records the time profile of a measurement signal which can be connected to the device. The arrangement provides high mapping accuracy of the measurement signal onto the recording signal at a low cost and with DC isolation between the measurement signal and drive means of the pen. The arrangement uses a control loop that has a pulse width modulator whose output is DC-decoupled to a signal converter that provides the drive signal for the motor that moves the pen.
