1176/EXP2 2277/EXP 2277/EXP2

Number of Inputs 1 or 2 depending on the mode selected. With mode 1, 2 inputs each with 128 leading edges recorded. In mode 2, 1 input with 128 leading and 128 trailing edges recorded. 4 or 8 depending on the mode selected. With mode 1, 8 inputs each with 64 leading edges recorded. In mode 2, 4 inputs with 64 leading and 64 trailing edges recorded. 2 with 128 leading and trailing edge capacity (128 pulses, measuring both leading and trailing edge).

Inputs 2 front panel Lemo connectors, 50 ohm for fast NIM signals, ORed with 2 front panel 2-pin headers for differential ECL, 100 ohm; 2 NIM (50 ohm Lemo) to differential ECL converters are provided for convenient operation with the 1176, 2277, 3377, 1876,1877. 110 ohm, differential ECL levels; 34-pin header. 2 front panel Lemo connectors, 50 ohm for fast NIM signals, ORed with 2 front panel 2-pin headers for differential ECL, 100 ohm; 2 NIM (50 ohm Lemo) to differential ECL converters are provided for convenient operation with the 1176, 2277, 3377, 1876,1877.
