time record, 1000 averages take exactly 4 seconds, during
which the SR785 still operates at its maximum display rate.
For impact testing, the average preview feature allows each
time record or spectrum to be accepted or rejected before
adding it to the measurement.
Order Tracking
Order tracking is used to evaluate the behavior of rotating
machinery. Measurement data is displayed as a function of
multiples of the shaft frequency (orders), rather than absolute
frequency. Combined with a waterfall plot, the SR785
provides a complete history or "order map" of your data as a
function of time or RPM. Using the slice feature, the ampli-
tude profile of specific orders in the map can be analyzed.
In tracked order mode the intensity of individual orders vs.
RPM is measured. Unlike other analyzers, there’s no need to
track a limited number of orders to ensure full speed
measurements. The SR785’s speed allows simultaneous
tracking of up to 400 orders.
Run-up and run-down measurements are available in both
polar and magnitude/phase formats. RPM profiling is
The SR785 tracks up to 400 orders simultaneously.
You can display the amplitude profile of any two
orders in tracked order mode.
