1 Display
All functions and parameters are displayed (8 lines with max. 40 characters).
2 Test On
By pressing the key "Test On" the test procedure is initiated with the preselected parameters. The red LED
indicates the trigger of a burst event.
3 Function keys "F1 .. F7"
Parameters and functions, displayed in the lowest line, can be selected with the related function key.
4 Knob (Inc / Dec)
The knob increments or decrements test parameters with a numeric value or selects from a list of parameters.
5 Cursor keys
Parameters and functions can be changed on-line. The selection of these parameters is realized with the cursor
moving to the left or to the right.
6 Exit
Pressing of the Exit function will cause a reset of the firmware. This is only possible if no test routine is running.
7 ESC
When pressing the ESC button the user moves back one page in the menu.
8 BNC - CRO Trigger
At the BNC output the generator trigger can be checked, e.g. the burst duration, the burst repetition rate and the
spike frequency (+15 V rectangular). This output signal can also be used to trigger external measuring devices
(e.g. an oscilloscope)
9 HV pulse output 50 ohm
External coupling devices such as the capacitive coupling clamp and the coupling network CNE 503 are
connected to the coaxial 50 ohm output. Also the pulse parameters, on 50
Ω
and 1000
Ω
load condition, must be
verified at this coaxial output.
10 Ground reference
During test or calibration procedure the burst generator must be grounded to the reference ground plane.
11 Coupling
The LED indicates that the pulses are coupled to the L –N –PE line.
12 EUT test supply
The coupling / decoupling network is part of the generator. The EUT is powered via the safety laboratory plugs
at the front panel of the simulator. The nominal power mains supply is 250V/16A. For higher currents, up to
100A, the external coupling network CNE 503 shall be used.
