Section 3 : Measuring with Transducers

The AGILENT 35670A can be used with a broad range of transducers. Transducers can use an external preamplifier to convert the raw signal into a voltage that is compatible with the AGILENT 35670A. Some transducers have internal circuitry which provides preamplification, however these internal circuits must be powered externally. The AGILENT 35670A can provide the necessary constant-current supply for transducers that are of type ICP, Isotron, Piezotron, DelaTron, Low Impedance, etc.

Using ICP-Type Transducers with the AGILENT 35670A

To set up Channel 1 for an ICP-type transducer:

•Press the [Input] hardkey

•Press [FRONT END CH1 SETUP] softkey (F7).

•Press [ICP SUPLY ON OFF] softkey (F8) until ON is highlighted.

Note that the analyzer automatically switches the front end to AC Coupling in order to reject the large DC signal that is generated by the constant-current supply.

To set up Channel 2 for an ICP transducer:

•Press the [Input] hardkey

• Press [CHANNEL 1 2 3 4] softkey (F1) until 2 is highlighted.

•Press [FRONT END CH2 SETUP] softkey (F7).

•Press [ICP SUPLY ON OFF] softkey (F8) until ON is highlighted.

For AGILENT 35670A analyzers with four channels, these same procedures can be repeated for Channels 3 and 4.

Using Transducers with External Preamplifiers

No special front end setup is required to use transducers with external preamplifiers except if the preamplifier’s DC component is too high, resulting in a loss of dynamic range. This can be easily minimized by switching to AC coupling as follows:

•Press the [Input] hardkey

•

Press [CHANNEL 1 2 3 4] softkey (F1) until 1 is highlighted.

•

Press [FRONT END CH1 SETUP] softkey (F7).

•Press [COUPLING AC DC] softkey (F5) until AC is highlighted.

A transducer with an external preamplifier will convert mechanical units (EU) to volts. Care must be taken to observe gain settings on the external preamplifier, because these gain settings directly affect the resulting transducer sensitivity.
