Summary
A description is given of a 15-channel digital data recorder for the 21-cm line receiver of the Stockert radio telescope. The voltages of the 12 receiver channels (10 line channels, one comparison channel for the continuum and one channel for checking) are scanned by a 12-point plotter. The signal at the rotary switch of the plotter is measured by first transforming it into a frequency (voltage-to-frequency-converter Dymec 2210) and then measured by counting the frequency over a fixed time interval (EPUT meter Beckman 7151 H). A digital clock gives the time of the measurement, and two angular position encoders (Hilger and Watts, London) give the elevation and the azimuth of the telescope during the measurement with 4 figures accuracy. All data are punched on an IBM 026 alphanumeric card punch.
