  7. Model 575 Features • System Modes • Independent Channel Modes • System Gating • Channel Gating • External Trigger • Channel Multiplexing • TTL/Adjustable Modes • Negative Delays • Channel Sync Source

  8. Existing FeaturesSystem Modes • Continuous • Pulses start at a specified rate once a trigger signal or the run/stop button is pressed • Burst • A specified number of pulses at a specific rate is output with every trigger or run/stop button press • Duty Cycle • A number of on pulse cycles followed by a number of off pulse cycles is started with a trigger or the run/stop button • Single Shot • One pulse out for every trigger signal or run/stop button press

  9. Existing FeaturesIndependent Channel Modes • All the same modes as the system but on a per channel basis. • The “normal” channel mode mimics the system mode without any additional setup • The output follows the system or channel mode; whichever is more restrictive

  10. Available Modes

  11. Existing FeaturesGating and Trigger • There are two forms of gating: system and channel • System gating effects all channels • Channel gating is specific to each individual channel • System gating and channel gating can not be operating at the same time • Trigger currently only operates on a system level

  12. Existing FeaturesChannel Multiplexing • Channel multiplexing allows for the combination of any or all channel settings to be output any of the outputs • Channel multiplexing only combines timing events of the channels and not the actual output voltages

  13. Channel Multiplexing

  14. Existing FeaturesTTL/Adjustable, Negative DelaysSynch Source • Standard TTL and Adjustable voltage outputs are available • Adjustable voltage up to 12V DC • Negative delay settings allow for one channel initiating prior to the synchronized source channel • Synchronize the timing of one channel to the timing events of another channel

  15. Negative Delay

  16. New Features • Gating-Output Inhibit • Gating-Pulse Inhibit • Low Jitter Trigger • Field Programmability • Illuminated Channel Enable • Selectable Clock-in • Selectable Clock-out • Saved Settings on Power Down • Illuminated Run/Stop Button

  17. New FeaturesGating-Output and Pulse Inhibit • System and Channel Gating can now operate in one of two ways-output inhibit or pulse inhibit • Output inhibit-Output is shut off when the gate signal is removed/added regardless of channel timing • Pulse inhibit-When the gate signal is removed/added the next pulse does not begin

  18. Gating- Pulse Inhibit

  19. New FeaturesField Programmability-Illuminated Channel and System Indicators • Both application and FPGA code is now field upgradable • New features can be added to instruments without the need to have the unit sent back • Illuminated indicators assist in trouble shooting customer problems over the telephone • Channel illumination indicates that the channel is enabled • Run/Stop button illumination indicates that the unit is armed • Trig/Gate button illumination indicated that the gate or trigger feature is enabled

  20. New FeaturesSetting Save at Shutdown • When the unit is shut down current system and channel setting are saved • When the unit is powered back up the saved settings are automatically restored • Saved settings is still available

  21. New FeaturesClock-in/Clock-out • Clock-in/Clock-out is now a standard feature • Clock-in can now except a number of frequencies in addition to 10MHz • Clock-out puts out a number of frequencies and the To frequency

  22. New FeaturesDecreased Jitter • External trigger jitter has been significantly decreased over the previous pulse generator • Jitter is specified as being <800ps RMS • Worst case jitter is 2.5ns
