4-92 Transducer Parameter Menu
SR785 Dynamic Signal Anaylzer
Transducer Parameter Submenu
Display the Transducer Parameters menu. Press <Return> or [Input] for the main [Input]
menu.
Transducers (such as accelerometers or microphones) convert a physical quantity (such
as acceleration or pressure) into a voltage at the analyzer’s input. By assigning
Transducer Units to an input, measurements based upon the transducer signal may be
displayed in units of the actual physical quantity being measured (such as m/s
2
or
Pascals).
Transducer Units require a transducer which is linear over the frequency range of
interest.
Measurements of inputs which are assigned units of acceleration, velocity or
displacement may be displayed with any of these three units using Transducer Convert in
the [Input]<Transducer Parameter> submenu.
Engineering Units
Select Engineering Units for the selected input [On, Off].
Measurements which require input data from an input which has Engineering Units On
will be displayed with units of EU Labels instead of Volts.
The two inputs may have different Engineering Units. For instance, if Ch2 has
engineering units On and EU Label set to Pascals, and Ch1 has engineering units off,
then the units of the frequency response measurement will be Pascals/Volt.
Note that this softkey applies to an input channel, unlike most softkeys which apply to a
specific display.
