Figure 5-11, Output Equations Menu
The Output Equations menu is used to define more complex calculations on the
instrument outputs than are possible using the basic ratio and log ratio options. There
are two user-defined equations, Equation 1 and Equation 2, which take the following
form:-
where the operator "±" may be set to either addition or subtraction, and the variables
A, B, C and D can be chosen from the following list:-
Variable Range
X ±30000
Y ±30000
MAG 0 to +30000
PHA (Phase) ±18000
ADC1 ±10000
ADC2 ±10000
ADC3 ±10000
ADC4 ±10000
C1 0 to 100000
C2 0 to 100000
0 Zero
1 Unity
FRQ (Reference Frequency)
0 to 250000000 (Only available in position C)
OSCF(Oscillator Frequency)
0 to 250000000 (Only available in position C)
The select keys are used to highlight the required variable, and then the adjust
keys are used to change it.
The values C1 and C2 within each equation are user-defined integer constants and
are adjusted using the two corresponding keys. They may also be set using
the keypad, by pressing SET CONSTANT followed by the required value on the
keypad, or by using the Active Cursor.
