6 L1/N selector switch
Provided that the HM605-2 is correctly con-
nected to the mains power outlet (item 4 )
LED 5 is lit after power-on. The EMC signal
immediately will be available at output jack
"Test Receiver" 11 . By pushing button 6
the signal source toggles to line N, which is
indicated by a LED 7 lit.
8 PE selector switch
After setting HM6050-1 to operation (power
on) the protective ground simulation circuit is
bypassed by default. After pushing button "PE"
8 the direct grounding of the protective earth
line (according to VDE 0877 Part 1/03.89) will
be replaced by a protective ground simulation
circuit (according to VDE 0877 Part 1/03.989
(89 (50µH II 50Ω to ground)).
10 Transient Limiter selector switch
After power-on the transient limiter circuit
is enabled by default, to protect the attached
Test Receiver's or Spectrum Analyzer's input
circuitry from high transient voltages. After
pushing button 10 the transient limiter cir-
cuit will be bypassed. A blinking red LED 12
indicates this operating status.
11 Test Receiver (test signal output)
The output impedance Z of the HM6050-2's test
signal output is 50Ω. The shielding connection
of the BNC jack is connected to the housing

C o n t r o l s a n d e l e m e n t s
and thus to ground. A two plug broadband
BNC cable is used to attach the HM6050-2
to a Test Receiver or Spectrum Analyzer. The
built-in transient limiter is enabled by default.
Pushing button 10 provides deactivation; LED
12 indicates this status by blinking.
13 RM - LED
In remote control mode „RM" LED is lit.
Attention!
Because of their test principles Test
Receivers and Spectrum Analyzers
(i.e. HM5012/14) are extremely
sensitive at their input circuitry. To
protect the input circuits from damage
by high voltage transients, it is highly
recommended to use the equipment
with the transient limiter enabled (red
LED off)! Due to switching the DUT on
and off, transients might arise, that
possibly can damage the input circuit
of the Spectrum Analyzer or Test Re-
ceiver. Damages of the input circuitry
resulting from transient voltages are
not covered by HAMEG's warranty.
