1-8. HP 5517D LASER HEAD
1-9 The HP 5517D laser head slew rate is compatible with HP 10780C/F receivers having serial number prefix 3546
or higher. Older receivers (such as HP 10780C/F receivers having serial number prefixes below 3546) may not work
with this laser head.
1-10. HP 5527B VERSUS HP 5527A
1-11 In order to handle the larger frequency difference of the HP 5517C changes were made in the HP 5527A, and
its Model Number was changed to HP 5527B. An HP 5527B can replace an HP 5527A, but the reverse is not always
true.
1-12. For making a measurement, an HP (lower frequency) Laser Head can be used with an HP 5527A, an HP
5527B. or an HP 5501A Laser Head.
1-13. For making a measurement, an HP 5517C (higher frequency) Laser Head can be used with an HP 5527B, but
not with an HP 5527A or an HP 5501A. The HP 5517D Laser Head may not be used with the HP 5507A, HP 5507B,
or HP 5501A.
1-14. TEST, ADJUSTMENT, AND TROUBLESHOOTING PROCEDURES
1-15 When an HP 5517B/C/D is used with an HP 5527B, installation, operation, and indications for procedures
described in this manual are the same as with an HP 5527A.
1-16. If an HP 5527B is not available (for use as a power source for an HP 5517B/C/D), an HP 5527A, an HP 10884A
(or even an HP 5501A) can be used. The test, adjustment, and troubleshooting procedures in this manual do not
depend on or require laser beam frequency. In these procedures, test points, adjustment points, and expected test
results for the HP 5517B/C/D are the same.
An HP 10946B/C Automatic Compensation Board may not necessarily work statically
with an HP 5517C.
1-16. During a typical measurement application, the laser beam travels through external optics where the horizontal
and vertical components of the beam are separated. One component travels along a fixed path and returns to an
external optical receiver. The other component travels along the path (axis) to be measured and then returns to the
external receiver. The external receiver detects the frequency difference between the two components and outputs a
signal called the MEASure Frequency. The MEASure Frequency from the external receiver and the REFerence
Frequency from the laser head are compared by external, user-selected electronics.
If the distance between the external optics is fixed, the MEASure and REFerence frequencies are equal. As the
relative distance between the external optics change, the MEASure Frequency changes due to a Doppler frequency
shift. This relative change between the MEASure and REFerence Frequencies is used by the system electronics to
compute distance traveled. The laser transducer system can be configured for computer control of open- and closed-
loop positioning and measuring applications, having single or multiple axes. For more detailed information, refer to
the HP 5527B Laser Transducer Position Designer's Guide Manual or the HP 5501A Laser Transducer Operating
and Service Manual.
