APB

APB

Add trace B and trace A, then enter sum in trace A. (A + B 7 A)

Example

30

OUTPUT

723;"SNGLS;"

Activate single-sweep mode.

40

OUTPUT 723;"RL 10DBM;SP 200NM;CENTERWL 950NM;"

Set measurement range.

50

OUTPUT

723;"TS;VIEW TRA;"

Sweep trace A and view results .

60

OUTPUT

723;"CLRW

TRB;TS;"

Clear write trace B. Sweep trace B.

70

OUTPUT

723;"AMB

ON;"

Subtract trace B from trace A.

Description The APB command adds traces A and B, point by point, then sends the result to trace A. Thus, APB can restore the original trace after A-minus-B function

(AMB) is executed. However, unlike AMB, the math operation is done only once, making APB equivalent to executing ADD TRA,TRA,TRB. Be sure data re￿ects one complete sweep for trace A and trace B by using SNGLS and TS.
