Time calibrator generates logic signals at precise time. Each output consists of pair of start and stop pulses. Operation of the time calibrator is simplified by controls that enable the operator to set to set some parameters of the signals.
Study operation of the time calibrator by using the oscilloscope. Before start connect the time calibrator and the oscilloscope in a proper way. Then turn ON the CAMAC crate and the time calibrator.
Turn the time calibrator controls PERIOD and RANGE to see what happens to the signals. To change the scale of oscilloscope screen use the control TIME. Why signals disappear when RANGE < PERIOD?
Study operation of the time calibrator using the time-to-digital converter (TDC). At first connect the time calibrator and the time-to-digital converter in a proper way. Then turn ON the CAMAC crate and the time calibrator.
Start the calibration procedure. Turn the PERIOD control on the front panel of the time calibrator. Look at the spectrum from the time calibrator and fill the table with the obtained data.
Analyze the obtained data, build the graph of dependence of the period between the START and STOP signals from the cannel number of the TDC. Make conclusions about linearity of the obtained graph and about the coefficient of straight line slope of the graph.
