This 6" wide module accepts a 1 Mhz bipolar experimental clock and repeats the clock at its output. It has a front panel thumb wheel switch to select one of 14 references time, INHIBIT, or EXTERNAL-IN. There are four sets of five digit 10 position thumbwheel switches, and four outputs corresponding to each set of thumbwheel switches. They are delayed time per 1, 10, or 100 uSec/unit (depending on the selection of 10K, 100K, 1Mhz ) with respect to the reference time. External reference time and the four basic reference times (main ring reset, start of ramp, beginning of flattop, and end of flattop) are available.
FRONT PANEL
Thumbwheel Switches
1)N1-Delay time with respect to reference time (R+N1)
2)N2-Delay time with respect to reference time (R+N2)
3)N3-Delay time with respect to reference time (R+N3)
4)N4-Delay time with respect to reference time (R+N4)
5) Ref. Time- Selects gaps 1 thru 14
Lights
1) 100usec - 100 usec/unit is selected
2) 10 usec - 10 usec/unit is selected
3) 1 usec - 1 usec/unit is selected
4) R+N1 - Flashes with pulse from N1 output
5) R+N2 - Flashes with pulse from N2 output
6) R+N3 - Flashes with pulse from N3 output
7) R+N4 - Flashes with pulse from N4 output
8) REF - Flashes when selected reference time fires
9)NIM-TTL - RED for NIM type, GREEN for TTL type
Rotary Knobs Selects
a) 100 usec - Switch setting 100 usec/unit
b) 10 usec - Switch setting 10 usec/unit
c) 1 usec - Switch setting 1 usec/unit
