Page 6: Functional Description
1.3. Functional description 1.3.1. Baseline generation The Mod. V793 generates two DC voltage levels (DAC1 and DAC2) which allows to set the baseline acquisition for the V791 boards; the DC levels can be remotely programmed with 12 bit resolution on the 0÷+2.5 V range either via RS232 or CAENET interface. For each V791 board, it is possible to select the baseline (DAC1 or DAC2) according to the type of signal to be converted by acting on a backplane jumper. -
Page 7: Test Pulses Distribution
16/01/01 1.3.5. Test pulses distribution During functional tests, a differential test pulse (±2.5 V range) can be injected into the V793 through the front panel PULSE IN connector (see block diagram at page 5); the pulse is splitted and then forwarded to the V791 modules or to the decoupling boards depending on the status of the CALIB_EVEN, CALIB_ODD, ENABLE_EVEN, ENABLE_ODD lines (TTL levels) as explained in the table below. -
