Please note:
There is a risk of destruction during HFW 21 operation when the differential-mode current is
measured and electrolytic capacitors are switched on or a short circuit occurs!
In such cases always connect the HFW 21 to the PA 203 or spectrum analyzer only after the
unit under test is switched on!

2.7 Measurement set-up

Figure 15 Measurement set-up ESA1 (schematic)
First place the GP 23 ground plate with its socket connectors pointing to the left (under normal
conditions) and set up the shielding tent (description in section 2.2).
Inside the shielding tent plug the PA 203 preamplifier into the BNC socket on the ground plate.
Power is supplied via the enclosed plug-in power supply unit; outside the shielding tent plug the
power supply unit into the 3.5 mm connector (next to the BNC socket) on the outer left side of the
ground plate. Inside the shielding tent connect the 12 V input of the PA 203 to the 3.5 mm
connector on the ground plate via the enclosed power supply cable (approx. 10 cm long, two
power supply plugs). The "ON" LED on the PA 203 must come on. Then connect the HFW 21 RF
current transformer or a near-field probe via the BNC-SMB connecting cable to the PA 203.
Connect the spectrum analyzer to the BNC socket on the outer left edge of the ground plate via the
enclosed BNC cable (double-shielded).
