10793A Keysight Laser Head Cable

The Keysight / Agilent 5527A/B Series Laser Position Transducer Systems are linear displacement measuring devices that provides laser interferometer accuracy to builders and users of precision positioning equipment. Designers can select from a variety of optics and electronics using only those components which solve specific measurement or control problems. With a single laser head, up to six axes of motion and one Wavelength Tracking Compensator axis may be monitored simultaneously. This flexibility benefits both end users and original equipment manufacturers (OEM's).

The Keysight / Agilent 5527A system consists of a two-frequency laser source, measurement optics, and electronics. Before the laser beam is emitted from the laser head, a portion of it is sampled to determine the difference in frequency between the two optical components. This difference frequency is called the Reference Frequency. The beam emitted from the laser head is directed through a configuration of optics and then to a receiver. The receiver provides a Measurement Frequency, which when compared to the Reference Frequency from the laser head, yields displacement information. In systems equipped with Wavelength Tracking Compensation, the above comparison yields wavelength information which is used to update the system compensation number. Three laser sources are available: the Keysight / Agilent 5517A, Keysight / Agilent 5517B, and Keysight / Agilent 5518A Laser Heads. The Keysight / Agilent 5527 system uses the Keysight / Agilent 107xx Series of optics. The electronics are the Keysight / Agilent 109xx Series of boards and are housed in the Keysight / Agilent 5507A Laser Position Transducer Electronics chassis. These boards are also available as Keysight / Agilent 5507A options.

In order to handle the larger frequency difference of the Keysight / Agilent 5517C, changes were made in the Keysight / Agilent 5527A, and its Model Number was changed to Keysight / Agilent 5527B. An Keysight / Agilent 5527B can replace a Keysight / Agilent 5527A, but the reverse is not always true.

For making a measurement, a Keysight / Agilent 5517B (lower frequency) Laser Head can be used with a Keysight / Agilent 5527A or a Keysight / Agilent 5527B.

For making a measurement, a Keysight / Agilent 5517C (higher frequency) Laser Head can be used with a Keysight / Agilent 5527B, but not with a Keysight / Agilent 5527A.
