1 Display
All functions and parameters are displayed (8 lines with max. 40 characters).
2
Function keys "F1 .. F7”
Parameters and functions, displayed in the lowest line, can be selected with the related function key.
3 Test On
By pressing the key "Test On" follows the functions:
- Activate the high voltage power unit; HV is ready to start.
- Switches ON the supply to the EUT test supply (only with built in PFS module).
- The LED indicates the trigger of a burst event.
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 CRO U (surge)
At the BNC output the voltage pulse (surge) of the generator can be measured galvanic separated.
- Impedance measuring instrument: >1M
Ω.
- Max. output voltage: 10V

10% at 5 kV / 7kV impulse voltage.
9 CRO I (surge)
At the BNC output the current pulse (surge) of the generator can be measured galvanic separated.
- Impedance measuring instrument: >1M
Ω.
- Max. output voltage: 10V

10% at 2.5 kA / 3.5kA output current.
10 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 (+5 V rectangular). This output can be generally used as oscilloscope trigger output and is
synchronous to the following events.
- Burst and surge release
- Voltage dip or interruption, start of the event
