Sampling Mode continued.
Frequency Maximum
The maximum frequency or order for the spectrum
measurement.
The sampling mode determines whether the
frequency maximum is specified in Hz or
orders. It also determines whether you enter a
value or choose a value from a list of available
values.
• If Sampling Mode is Synchronous with
tach, enter the Frequency Maximum value.
The frequency maximum range for
synchronous sampling mode is 4...200
orders.
• If Sampling Mode is Asynchronous, choose
the Frequency Maximum value. Note you
may enter a specific value if you choose 10
to 5000 range. Supported maximum
asynchronous frequencies are dependent
on sensitivity units and full scale units you
choose on the Channel tab. See tables
below.
