Variations On This Implementation

1. The module could be set to begin generating the waveform in response to an external or backplane TTL Trigger.

2. The module could be set to generate external triggers for each point in the List. This trigger could be routed to other

instruments to synchronize external measurements to the change in voltage. (see application #7) Using this technique,

parametric measurements could be made on the device during the thermal cycling.

3. Multiple modules could be programmed to cycle together in response to the computer trigger command.

4. To determine how many times the hybrid was cycled before it failed, you can use the SRQ (that was generated when the

hybrid failed and the module went into CC) to timestamp the failure. The elapsed time will give the number of cycles

executed.
