The Traces Menus
To set the Hold.... function
1Press the
2Press the Hold <trace>.... softkey to select None, Min or Max. None turns the Hold function off.
The maximum hold function compares the current amplitude value of each point on a trace in the current sweep to the corresponding point detected dur- ing the previous sweep, then displays the maximum value.
The minimum hold function compares the current amplitude value of each point on a trace in the current sweep to the corresponding point detected dur- ing the previous sweep, then displays the minimum value.
Pressing the Max/Min Reset softkey resets the hold function to the last acquired trace. Subsequent traces are accumulated in the hold sequence.
To set the trace math for trace C
1Press the
2Press the Trace Math.... softkey.
3Press the Default Math Trace C.... softkey to define the math expression to be used when the math operations are turned on. The result is placed in Trace C.
4Select the appropriate softkey to define the math expression.
Defines the math expression to be used and turns the math operation ON. The math operation is performed in linear units.
