13 General Instrument Setup
The general instrument settings are available in all operating modes.
13.1 Resetting the Instrument
Reset is helpful if the instrument is in undefined condition and cannot be operated.
►
To switch off the instrument and reset the hardware, press the
power key for 5
seconds.
► To restore the factory settings, hold down the [PRESET] key during the boot proc-
ess.
13.2 Disabling the Touchscreen
In certain situations, the capacitive touchscreen can get stimulated without touching it.
Typical situations are:
●
Measuring in an environment with immissions considerably higher than specified
●
Measuring on power electronics with strong electric fields
●
Connecting the probe to power electronics DUTs with large voltages or fast rising
edges
Due to the unwanted stimulation, the R&S RTH detects three or more fingers on the
screen even though the display has not been touched. A message box informs about
the detection of more than two fingers. In this case, operate the instrument using the
keys and the wheel and disable the touchscreen.
► To disable the touchscreen, press the [SHIFT] key for 2 seconds.
13.3 Selfalignment
Access:
or "Setup" menu > "Selfalignment"
The self-alignment aligns the data from several input channels vertically and horizon-
tally to synchronize the timebases, amplitudes and positions.
Recommendation on performing the self-alignment:
●
When putting the instrument into operation for the first time
●
After a firmware update
●
Once a week
●
When major temperature changes occur (> 5°)
