Entering the Total Signal RMS
Use The total voltage is divided between the useful and interference signal in the
(selectable) ratio. The maximum voltage setting is limited by the maximum
peak value. As a result, the limits for the user-selectable RMS depend on the
amplitude ratio.
Selecting
the channel 1. Press the numeric keys 1 , 2 , or 3 to select channel Ch 1 , Ch 2 , or both
channels Ch 1&2 .
The selected channel is displayed in green in the channel display.
Entering the
total signal RMS
2. Press the function key in the menu.
An entry field containing the currently applicable setting is displayed. The
default setting is “100 mV (0.1 FS)”. At the same time, the function keys
[13] are assigned various units of measurement.
Analog Digital
3. Enter a new value ( Ê 5-65).
The permissible entry range depends on amplitude ratio:

Note: The maximum limit of signal amplitude applies if only the SINE MOD
DIST generator function is set. If other generator functions (e.g. DC OFFSET,
NOISE) are activated, their amplitude will also be taken into
consideration and the maximum signal amplitude decreases accordingly.
