    2 Custom Modifications The 9412/9412A is microprocessor - controlled and employs a flexible and expandable user - interface. New features and operating modes often can be added, without hardware modif i- cations, by merely modifying the software contained inside the 9412/9412A. Most modific a- tions can be made for a very modest charge -- conta ct ...

    13 Main Menu The Main Menu consists of a set of menu selections used to set the operating mode, time p e- riod and frequency of the 9412/9412A. MODE - Pulse Modes There are five (5) different Pulse modes available. Continuous Mode While in Continuous mode, the 9412/9412A will generate pulses at the rate set by the inte r nal To Period as set in the ...

  • Quantum Quantum Composers - page 14

    14 Duty Cycle The Duty Cycle mode is similar to Continuous mode in that a continuous stream of pulses is output. The exception is the outputs are only active for a set number of seconds ( DC:On menu), then disabled for another set time period ( DC:Off menu) before being re - enabled. This cycle is repeated for a set number of times ( CYCLES menu), ...

    15 ToPer - To Period Except when in External Trigger or Single Shot mode, all pulse outputs are based on an i n te r- nal timer called To. This menu is used to select the rate at which To runs by selecting the time period in microseconds between timer pulses. When in Continuous, Burst, or Duty C y cle mode, pulses are out put at the rate determined ...

    16 When set to Positive , the output will initially be at 0 Volts. When active, will go high for the specified pulse width time, after which it will return to 0. The voltage level while high w ill d e- pend upon the load and the setting of the output voltage adjustment on the back panel. If set to Negative , the output will normally be at the high ...

    17 T2:Wait The output of Channel 2 can be delayed for a number of pulses. This menu is used to set the number of pulses that must occur on the other channels before the output o f Channel 2 is e n- abled. This is particularly useful when using Channel 2 as a Q - switch trigger, as it allows the laser to thermally stabilize before activa t ing the Q ...

    22 P P CR is a carriage return character (ASCII value 13). With echo enabled, all characters sent will be echoed back to the sender. Unidentified commands and most out of range conditions result in the pulse generator igno r ing the command. If the command is properly identified, the pulse generator returns an ok fo l- lo wed by a carriage return a ...
