=== CIRCUIT LIST TYPE WORDS ===
Each type word is parsed for first letter, first two letters, then first
three letters of an 8-character maximum type word. Any character after
first identification is only for user's reference designation. Capitals
are shown only for emphasis; either upper- or lower-case may be entered.
--- SINGLE-BRANCH TYPES ---
END EN E = End circuit description; non-branch, enter in
ND N type designation to signify end of circuit.
BAK BA B = Non-branch, enter in place of type designation
to move BACK to previous branch for re-entry.
RESist RES RE R = Single resistor.
CAPaci CAP CA C = Single capacitor.
INDuct IND IN L = Single capacitor.
LQ = Single Inductor with frequency-independent Q.
CQ = Single Capacitor with frequency-independent Q.
SRL RL = Series Resistor-Inductor.
SRC RC = Series Resistor-Capacitor.
PRC = Parallel Resistor-Capacitor.
PRL = Parallel Resistor-Inductor.
IDC DC D = DC-only independent current source.
SIGnal SIG SI S = Independent current source ("signal generator").
GMS GM G = Transconductance-specified dependent Current source.
HFS HF H = Current-Gain-specified dependent Current source,
--- MACROMODEL TYPES ---
QTR QT Q = Bipolar Transistor (hybrid-pi model), 3 nodes,
4 branch spaces. Specify: hfe, Ic, Ft, hoe.
TRF TR T = Two-winding isolated transformer, 4 nodes, 4 branch
spaces. Specify: Pri. induct., coupling coefficient,
turns ratio Primary:Secondary.
OPA OP O = Operational amplifier, 1 break-point, 1 common
connection; 4 nodes, 5 branch spaces; both non-
inverting and inverting inputs, one output.
Specify: Open loop voltage gain in db, internal break
point frequency at -3 db point, output resistance,
input resistance each input (both equal).
ZLN ZL Z = Transmission line (unbalanced), 3 nodes, 3 branch
spaces. Specify: Characteristic impedance, velocity
of propagation, length in inches, attenuation as db
per hundred feet of length.
--- MAXIMUM CIRCUIT SIZE ---
200 branches maximum if last component is macromodel,
204 branches maximum if last 4 are single branches.
56 Nodes maximum.
