Application Examples
Time Interval Mode for Time Delay
For periodic pulses applied to A and B channels, time delays can
be measured down to 0.2 µs resolution from the rising or falling
edge of A to the rising or falling edge of B (selectable).
Time Interval Mode for Time Delay
The width of periodic pulses (t1 or t2) can be measured by tying
the A and B channels together. As for time delay, readings are
averaged over a user-selectable gate time.
Timing Process Dynamics
The start and stop pulses used for timing can be generated by
the dual relay board in a Laureate panel meter or digital counter.
For instance, the start and stop pulse edges can be created as
temperature passes two alarm setpoints, or temperature cycles
in a hysteresis control mode.
Rate Based on 1 / Time
The start and stop pulses used for timing can be generated by
the dual relay board in a Laureate panel meter or digital counter.
For instance, the start and stop pulse edges can be created as
temperature passes two alarm setpoints, or temperature cycles
in a hysteresis control mode.
Replacing an Oscilloscope with a Laureate Meter
An oscilloscope is great for viewing and timing pulses in a lab.
However, in fixed installations where digital timing accuracy and
control outputs are required, a low-cost Laureate time interval
meter will be the instrument of choice. Resolution to 0.2 µs is
feasible.
Instrumenting a Pulsed Laser System
Some of the many possibilities in instrumenting a pulsed laser system with Laureate dual-channel
counters: elapsed time, number of pulses, pulse width, pulse separation, duty cycle, and pulse rep rate.
