1Display
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 and functions displayed with ” F “, can be selected
with the related function key.
3 Test On
By pressing the key "TEST ON", the RF signal will be released and the test procedure can be started.
4 Knob (Inc / Dec)
This knob increments or decrements parameters with a numeric value or selects parameters from a list.
5Cursor Key
Parameters and functions can be changed during the test. The selection of these parameters is done with
the cursor, moving it to the left or to the right.
6 EXIT
The EXIT button resets the firmware to the main menu. This is only possible, if no test routine is running.
7 ESC
The ESC button returns back to the previous level in the menu.
8 RF-Output
At this output the RF power is available. The 3dB-attenuator is connected, if available, via coaxial cable.
For conducted tests together with CDN’s, EM clamps or current injection clamps, it may be suggested to
load the simulator with a matched 50 ohm load. In case the above mentioned coupling device may not
represent such matched load, then it is recommended to add a 3dB attenuator in between.
9 LED RF Output Monitor
When the RF output is active this LED on the front panel is illuminated to indicate that a test signal is
generated.
10 Current Probe Input
For tests with a current injection clamp where the EUT current has to be measured and/or monitored, the
current probe can be connected to this input.
ATTENTION: Do not connect the RF output directly to this input otherwise it will be damaged.
