When the selected measurement time range selectable in steps of 6 4 ns has elapsed the sweep and so the data acquisition ends After a short 96 ns end of sweep dead time the MCS6 is ready for a new start and will begin a new sweep as soon as the next START event occurs MF FFT ComTec GmbH 4 1 Functional Description To reduce the overall average data rate a HOLD OFF time might be selected as well in steps of 6 4 ns that allows a new start only after this additional time has elapsed after the end of the sweep Acquisition delay time range and hold off are 48 bit values in 6 4 ns units each Acq Delay TimeRange Hold Off lt 2 x 6 4 ns 20 days max Since the time window in which events are actually acquired is programmable in such a wide range it is possible to count stop events at very high input rates even at late arrival times This is due to the data reduction executed The fact is that all events that occur outside the programmed time range window are discarded Example 1 Average STOP data rate of 100 MHz Interesting time window is 1 us at 1 ms after the START TRIGGER signal In a time range of 1 ms the 100 MHz input rate would result in 100 000 STOP events which would cause data loss due to filled FIFO s When programming an acquisition offset of 1 ms and a 1 us measurement time window the resulting number of events per sweep is only 100 Thus no data loss at all will occur And even with highest speed swee

19. Hardware Description WARNING Take care not to exceed the maximum input voltages as described in the technical data Discriminator Propagation Delay Dispersion The input discriminators propagation delay varies slightly with input overdrive voltage and slew rate When overdrive varies from 10 mV to 500 mV and slew rate varies from 1 V ns to 10 V ns the delay can vary for up to 25 ps which is of the bin width This specification applies for both positive and negative going signals For overdrive voltages above 200 mV the delay variation due to overdrive dispersion is mostly negligible Monitoring the Inputs To ease the adjustment of the threshold levels the discriminator outputs are sampled at a frequency of 312 5 MHz cor 3 2 ns and can be output on the SYNC outputs Preferable SYNC_ 1 should be used as it is a fast NIM output and provides best speed and edge rates Due to the 3 2 ns sampling the delay of the monitor signal relative to the input pulse will vary by 3 2 ns as well The minimum output pulse width will be 3 2 ns and thus even for very narrow input pulses only 300 500 MHz scopes are necessary to see the monitor signals Be aware that for pulses smaller than 3 2 ns the detection probability will be below 1 i e pulse width ns 3 2 NOTE this is only true for the monitor output and not for the spectrum acquisition For spectrum acquisition the pulses can be as narrow as 100 ps and still are 100 detected A Co
