Power Supply Function
4.6.3.3 42V Road Vehicles — Electrical and Electronic Equipment for
a Supply Voltage of 42 V — Electrical loads
A test wave completely conforming to International Standard ISO21848 is built
inside the device, which can be used for the test of Electrical and electronic
equipment for a supply voltage of 42V - Electrical loads. The user can directly
and quickly recall this function during test.

Take Momentary-Drop as an example to introduce the procedures as follows:
1. Press the composite keys [Shift]+[I-set] (Function) on the front panel to en-
ter the function menu.
2. Use the knob to select 3.Road-Vehicles = Off and press [Enter].
3. Press the Left/Right key to select ISO21848, and press [Enter] to confirm.
4. Press the Left/Right key to select Momentary-Drop, and press [Enter] to
confirm.
The interface returns to the main interface of the system and displays
MOMENTARY-DROP.
5. Press [On/Off] on the front panel to turn on the output.
6. According to the selected trigger method (same as the trigger method of the
LIST function), for example, press [Shift]+[On/Off](Trigger) to trigger the
output of the waveform.
