AMB Trace A Minus Trace B
Syntax
Figure 7-45 AMB Syntax
Description
The AMB command subtracts the contents of trace B from trace A and
places the result in dBm (when in log mode) in trace A. When in linear
mode, the result is in volts. If trace A is in clear-write or max-hold
mode, this function is continuous. When AMB is active, an "M" appears
on the left side of the display. The command AMBPL overrides AMB.
For more information on trace math, refer to Chapter 5.
NOTE The displayed amplitude of each trace element falls in one of 600 data
points. Thereare 10 points of overrange, which corresponds to one-sixth
of a division of overrange. When adding or subtracting trace data, any
results exceeding this limit are clipped at the limit.
