HP 3562A Operating Manual page 356

SYNTH-displays the synthesis menu. The H P 3562A can synthesize frequency response
curves containing up to 40 poles and 40 zeros. Data can be entered in pole/zero,
pole/residue or polynomial formats. You can also synthesize constants for use in math
operations. To synthesize linear traces, put the instrument in the linear resolution
mode. For log traces, select the log resolution mode.
Press POLE ZERO, POLE RESIDU or POLY NOMIAL to select the type of synthesIs
and display its table. To convert from one type to another, use the CONVRT TABLE
menu. To erase one type and enter another, press the desired type. This displays a
blank table, and as soon as you press one of the editing soft keys the old table is
erased.
ADD VALUE-adds a vEJue after the edit value in the synthesis table. The edit vEJue is
selected with EDIT DENOM#, EDIT N U M ER#, E D IT POLE#, EDIT
RESIDU#, or EDIT ZERO# (depending on the type of synthesis). To add a
vEJue before the first one in the table, move the pointer to line #0 (above line
#1), then enter the new value. To enter a real-only vEJue, enter the value then
press one ofthe units softkeys. To enter a complex vEJue, enter the real and
imaginary vEJues separated by a comma (,) then press one of the units soft­
keys.
CHANGE VALUE-used to change the edit value in the synthesis table. The edit val u e
is selected with EDIT DENOM#, EDIT N U MER#, EDIT POLE#, EDIT
RESIDU#, or EDIT ZERO# (depending on the type of synthesis). To enter a
real-only value, enter the value then press one ofthe units softkeys. To enter
a complex value, enter the real and imaginary values separated by a
comma (,) then press one of the softkeys.
CLEAR TABLE-clears the synthesis table. The message "Push Again to Clear" is
displayed to allow you to confirm that the table is to be cleared. Once
cleared, tables cannot be recovered. Hoewever, they can be saved in disc
memory; see
CONVRT TABLE--displays the convert table menu, which converts synthesis tables
to one of the other two types. For example, you can convert a pole/zero
table to ratio-of-polynomials format by pressing CONVRT TABLE followed

CREATE CONST -used to create a constant value for use in waveform math. To
create a real-only constant, press CREATE CONST, enter the value with the
0-9
keys in the Entry group, then press ENTER. To create a complex con­
stant, press CREATE CONST, enter the real and imaginary values sepa­
rated by a comma (,) then press ENTER.
CREATE TRACE-synthesizes a trace using the selected synthesis table. "SYN­
THESIS IN PROGRESS" is displayed while the trace is being created, and
the synthesized trace is labeled "SYNTHESIS."
