HP 5501A Operating And Service Manual page 18

Remember that deciding how to physically mount the individual units on your equipment is
only done once (provided it i s done correctly). Therefore, be sure that you have examined
all the factors that will affect your measurements. It is well worthwhile to spend extra time
before mounting the equipment to minimize equipment downtime later.
1.4 Section Ill, System Electronics
The system electronics are covered a s follows:
a. A brief description of the overall function of the system electronics.
b. HP-IB Interface Electronics.
c. Computer l nterface Electronics
d. English/Metric Pulse Output Electronics.
e. 10781A Pulse Converter Electronics.
f. Theory of operation for each individual unit.
In this section you need only read the areas that directly pertain to your system.
1.5 Section IV, Programming
The programming section is also divided according to system configuration. However, some
of the most useful information you will find in this section are the block diagrams that show
the movement of data between units of the system. This movement is similar for all type sys-
tems and therefore each example can be studied to increase your overall system knowledge.
The information is presented a s follows:
a.
A general discussion of the aims and methods of programming the Laser Transducer
System.
b. A table of individual commands for each unit of the system that is programmable.
c. Commented programs and examples of measurements and data movement using the
9825A Calculator a s the system controller and the 10745A HP-IB Interface.
d. Commented programs and examples of measurements and data movement using the
10746A Binary Interface. The 9825A Calculator i s used a s the system controller but
the program illustrates how a computer could be used instead of the 9825A.
e. A general discussion with examples of data handling after the data has been trans-
ferred to the system controller.
f. A general discussion of how to debug (remove errors from) your program. Specific
examples of common errors are given.
NOTE
The operating procedures (other than initial turn on) for the
Laser Transducer System are dependent on the programming
or design of the system controller.
g.
General operating instructions for a typical system and a brief explanation of the con-
trols on applicable units.
