However, you can use this feature for the other input channel. In this case, the active
display is not affected but other measurements based upon the other input are affected.
User Label
Enter the User Label for the selected input Engineering Units. Use the [ALT] keys (for
alphabetic entry) to enter a user defined name for the engineering units. The displayed
units change from Volts to the User Label when Engineering Units are On and USER is
chosen for the EU Label.
Note that this softkey applies to an input channel, unlike most softkeys which apply to a
specific display.
Command: EU1U (?) {s}
EU2U (?) {s}
Transducer Convert
Select the Transducer Conversion for the selected input. Transducer conversion only has
an effect for measurements of inputs with Transducer Units of acceleration, velocity, or
displacement.
Transducers (such as accelerometers) convert a physical quantity, (such as acceleration)
into a voltage at the analyzer's input. By assigning Transducer Units to an input,
measurements based upon the transudcer signal (acceleration) may be displayed in units
of the actual physical quantity being measured (velocity or displacement). Transducer
conversion is accomplished in the frequency domain by multiplying and dividing by j
ω
which is equivalent to differentiating and integrating in the time domain.
The two input channels may have different transducer conversions.
