4 Test Setup
Putting the R&S ESH3-Z6 into operation
1. Remove the nut that secures the safety cap (both front and back).
2. Remove the safety cap.
3.
DANGER! Risk of electric shock. Before you connect the V-network to the power
source, you have to connect the R&S ESH3-Z6 to a protective ground terminal. An
unearthed R&S ESH3-Z6 is live. Touching a live electrical device causes serious
personal injury, or even death.
The protective ground connection must remain until you have disconnected the V-
network from the power supply.
Connect the R&S
ESH3-Z6 to a reference ground.
a) Connect the ground terminals X1.2 and X2.2 to a protective ground terminal.
b) Screw on the safety nuts to secure the ground cables.
c) If required by the test setup: Connect the ground plate to a protective ground
terminal via the notches in the ground plate.
The R&S ESH3-Z6 has a single current path from X1.1 to X2.1. Therefore, the
ground terminals may only be used as a return line if the EUT and its generator
use reference ground as a return line (for example in case of low-voltage net-
works).
If the supply lines are isolated from the reference ground, you have to feed each
line into a separate R&S
ESH3-Z6 as shown in Figure 4-1 . In that case, you have
to connect both V-networks to a protective ground terminal.
4. Make sure that the R&S ESH3-Z6 gets enough ventilation.
5. Connect the EUT to the power connector on the front side.
6. Connect the power connector on the back side of the R&S ESH3-Z6 to the power
source.
Route the cables as specified by CISPR or as if no V-network were there.
7. Put the safety caps back on.
8. Secure the safety caps with the nut.
9.
NOTICE! Risk of intrument damage. We recommend to keep the test receiver dis-
connected when you turn the power on or off. High power pulses that occur while
turning the power on and off can damage the test receiver.
Connect the RF output to the RF input of a test receiver with a 50
Ω
coaxial cable.
The test receiver shows the disturbance voltages in dBµV.
