In particular, the output width in Burst Guard mode will be proportional to the input width. In the Updating mode, the leading edge of the input pulse triggers the discriminator timing stage. The Sync-Strobe Input requires complementary NIM signal levels. For more details see Chapter 4, Operating In- structions. The output of 4413 is differential ECL pulse pairs suitable for driving twisted-pair cables.
Minimum width is set by turning the potentiometer fully counter clockwise.
The main contributors to output width uncertainty are a function of the external conditions. Variations in both temperature and supply voltage can cause significant changes in output width. The two connectors allow cascading of several units if needed. In this case, care should be taken to terminate the unused output to avoid reflectors. Figure 4 shows an example of the current sum output with only one load.
