Auto Math
The HP 3563A's auto math feature allows you to program math operations using the Active Trace
keys and the softkeys in the MATH and MEAS OISP menus. The current auto math table is saved in
nonvolatile memory inside the instrument and is not erased when power is removed. Tables can also
be stored in disc memory; see chapter 11 for instructions. The next two sections explain how to
program and start the auto math table.
An important feature of auto math is that it can be selected as a measurement display in the linear,
log and swept sine modes. This allows you to view the math results while a measurement is in
progress.
The table is limited to
99
used. (The limit is 99 lines or 1200 characters.) The message in the top right corner of the table
Keys Left" tells you how many key strokes are available. Also, keep in mind the instrument states
under which you may run the auto math table. A table created to operate on a given set of traces
may not work if you (or the analyzer) provide different traces.

Programming the Auto Math table

Commands are programmed in the auto math table in the same manner as they are executed directly
from the front panel. For example, to add trace
as a command. You can select one measurement display for each trace, and the MEAS OISP
selections must precede the MATH selections. To fill or edit the auto math table, press AUTO
MATH. Figure 15-18 shows the menu diagram for AUTO MATH.
Note
You must pause the measurement (press PAUSE/CaNT) to edit the auto-math
table.
