Remote command:
CALCulate<Chn>:SMOothing:APERture
Hold
Selects the "Max Hold" (peak hold) or "Min Hold" function for the active trace, or disa-
bles both functions ("Hold Off"). With enabled "Max Hold" or "Min Hold" function, the
displayed trace shows the maximum or minimum values that the analyzer acquired
since the start of the measurement. The "Max Hold" and "Min Hold" traces are real;
they are based on the magnitude of the trace values (the phase values are discarded).
The "Hold" process can be restarted any time using "Restart" (current trace) or
"Restart All" (all traces in the active recall set). The "Hold" process is also restarted
automatically when the channel or trace settings are changed so that the previous
measurement results are no longer compatible.
Note: A memory trace is unformatted by definition. Therefore, a "to memory" operation
on a "Hold" trace actually stores the last measured trace data instead of the current
"Max Hold" or "Min Hold" values.
Remote command:
CALCulate<Chn>:PHOLd
Shift Trace
Functions for shifting the active trace in horizontal and vertical direction.
Stimulus ← Shift Trace
Shifts the active trace in horizontal direction, leaving the positions of all markers
unchanged. The unit of the offset value depends on the sweep type.
Note:
A "Stimulus" shift can be used in cartesian and in complex diagrams. The visible effect
depends on the diagram type:
●
In cartesian diagrams, the trace is shifted relative to the markers and the x-axis.
●
In complex diagrams, the trace is not affected.
Remote command:
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:X:OFFSet
Mag / Phase / Real / Imag ← Shift Trace
Modifies the active trace by adding and/or multiplying complex constants.
The trace points are modified according to the following formula:
M
new
The formula and the different constants are adjusted to the different display formats of
a trace:
●
The "Mag" factor shifts a dB Mag trace in vertical direction, leaving the phase of a
complex parameter unchanged.
●
The "Phase" factor rotates a trace that is displayed in a polar diagram around the
origin, leaving the magnitude unchanged.
●
The "Real" value shifts a real trace in vertical direction, leaving the imaginary part
unchanged.
