Remote control
The functions L1, N and 150 kHz HP can be controlled remotely by applying a static
LOW level to the appropriate contact of the SUB-D25 female connector (1) on the rear
of the R&S
AMN6500.

When a LOW signal is detected at input L1, N or 150 kHz HP, the corresponding func-
tion is activated and manual operation is blocked at the same time. The functions that
have been switched on are indicated by the associated LEDs. When remote control is
active, the REMOTE LED is lit.
When the LOW signal is removed, manual operation is enabled again and the status
set manually prior to the remote operation is restored.
The settings are not saved if the device is disconnected from mains supply; instead,
the default status ( L1 "ON" and 150 kHz HP "OFF") is always restored when mains
power is switched on.
The R&S
AMN6500 is configured for direct connection to Rohde
&
Schwarz test
receivers.
If remote control is performed via an R&S receiver, the REMOTE LED is lit when the
"ENV216" type network is selected. The user can choose between Phase "N" and "L1".
The 150-kHz-highpass filter can be inserted into the signal path by pressing the "On"
softkey in the LISN Settings dialog on the receiver.
The pulse limiter is not remote controllable. For safety reasons at remote control the
pulse limiter is turned on. If it is assumed, that the pulse limiting influences the noise
spectrum, it can be manually remeasured.
