Step 5. Install Ferrite Cores; Step 6. Start Up The Analyzer - Agilent Technologies PNA series Installation And Quick Start Manual

STEP 5. Install Ferrite Cores

CISPR 11 is an international regulation that specifies the maximum level of frequency emissions that
can originate from an electronic device. The regulation is designed to minimize the interference that
one electronic device may have with another.
Frequency emissions can occur when cables are connected to an electronic device. To minimize this,
try to use high-quality cables with built-in molded ferrite cores, with the core closest to the PNA. If
cables with built-in cores cannot be found, use one of the clamp-on ferrite cores that are included with
the PNA. It is especially important to use these cores on USB cables and LAN cables.
The core should snap closed to grip the cable firmly, but without damaging the cable. Attach the core to
the cable as close as possible to the PNA connector end. Cable ties are included to help ensure that the
ferrite cores remain in place.

STEP 6. Start Up the Analyzer

CAUTION Install the instrument so that the detachable power cord is readily identifiable and is
easily reached by the operator. The detachable power cord is the instrument
disconnecting device. It disconnects the mains circuits from the mains supply before
other parts of the instrument. The front panel switch is only a ON/Standby switch and
is not a LINE (OFF) switch. Alternatively, an externally installed switch or circuit
breaker (which is readily identifiable and is easily reached by the operator) may be
used as a disconnecting device.
1. Connect the AC power cable.
