The sweep is stopped and the trace is not displayed.
Exchange A and B
EX
1.
The sweep is stopped. If either trace is in a CLEAR WRITE or MAX HOLD mode, it is placed in VIEW.
2.
The contents of traces A and B are exchanged.
1.
The sweep is stopped and trace B is placed in VIEW mode.
2.
A is replaced with A - B (A minus B) .
3.
The sweep is continued from the left. Each new analyzer response point is reduced by the amount stored in
the corresponding address of trace B, and the result is stored in trace A. This process continues at the sweep
rate.
Subsequent sweeps continue the process.
4.
A
1.
Subsequent analyzer responses are written directly into trace A. Trace B and its mode are not changed.
2.
The amplitude stored in the display line register is subtracted from the contents in each trace B address and
the result is stored at the same trace B address.
B
1.
Trace B is placed in view. Trace A is not changed.
2.
The amplitude stored in the display line register is subtracted from the contents in each trace B address. The
result is stored at the same trace B address.
