POSITION
In a normal waveform window, the rotary knob changes the trigger offset. The trigger
offset is the horizontal position of the trigger point in relation to the reference point - the
zero point of the grid. Thus, you can set the trigger point even outside the diagram and
analyze the signal some time before or after the trigger.
Turn clockwise to move the position to the right, and press the knob to reset the value.
At zero-crossing, the knob shortly snaps in and the setting is kept constant to simplify
the zero-setting.
If a zoom or FFT window is displayed, the knob can change other specific horizontal
parameters as well. To toggle the parameters, press the SCALE rotary knob.
SCALE
In a normal waveform window, the rotary knob adjusts the time scale of the horizontal
axis for all signals, also known as time base. Turn clockwise to stretch the waveforms -
the scale value time/div decreases. The current value is shown in the information bar, it
is the left-most value indicated by "TB:".
If a zoom or FFT window is displayed, press the knob to toggle between the windows
and their horizontal parameters, then turn the knob to adjust the selected scale value.
Pressing the SCALE knob toggles also the parameter changed by the POSITION
knob.
ZOOM
Provides functions for configuring the ZOOM display for detailed signal observation.
HISTORY
If option R&S
RTM-K15 is installed, the memory can store more acquisitions than dis-
played. The HISTORY key opens the "History" menu where you can view the stored
segments and use them for further analysis.
If option R&S
RTM-K15 is not available, the key does not have any function.
NEXT
Moves the next (right) marker to the reference point of the display or zoom area. If a
search is enabled, the key navigates the search result markers.
