To specify a transducer’s unit and sensitivity
1 Press [
Input
], then press [
CHANNEL 1 2
] (or [
CHANNEL 1 2 3 4
]) to highlight the channel
connected to the transducer.
2 Press [
XDCR UNIT CHx SETUP
][
XDCR UNIT LABEL
]. (You can also press
[
MORE CHOICES
] to display additional units.)
3 If one of the displayed menus includes your transducer’s input unit, press the
corresponding softkey.
or
If neither menu includes your transducer’s input unit, you can enter the unit yourself
(from the [
MORE CHOICES
] menu): press [
USER LABEL
][
USER UNIT LABEL
]
[
CLEAR ENTRY
], then type a label and press [
ENTER
].
4 Press [

5 If you want the new unit and sensitivity factored into displayed amplitudes, press
[
XDCR UNIT ON OFF
] to highlight ON.
The Agilent 35670A allows you to measure mechanical devices with a transducer.
The transducer must produce an output voltage that’s proportional to some input
energy over the range of frequencies measured. The unit you specify in this task is the
one that’s used to quantify the input energy. The sensitivity you enter is the nominal
sensitivity (or calibration factor) of the transducer. The unit and sensitivity settings
are not lost when you preset or turn off the analyzer. Their use is disabled, however,
because [
XDCR UNIT ON OFF
] is set to OFF.
There is an advantage to directly selecting your transducer’s input unit instead of
entering a user unit label in step 3. If you select one of the acceleration, velocity, or
displacement units, you will be able to quickly convert displayed amplitudes from one
of these units to another. The next task shows you how.
You can enter transducer sensitivity in V/EU, EU/V, or dB referenced to 1 V/EU. (EU
is an abbreviation for engineering units—an alternate name for transducer units.) You
can also enter transducer sensitivity using a calibrator and the [
CAL VALUE AT MKR
]
softkey. For more information on using a calibrator, see “To calibrate a transducer” in
chapter 1.
