Power Cable and Grounding Requirements
On the GPIB connector, pin 12 and pins 18 through 24 are connected to chassis
ground and the GPIB cable shield. The instrument frame, chassis, covers, and
the BNC connectors’ outer shell for the source, trigger, channel 1, and external
arm are connected to chassis ground. If option AY7 (second input channel) is
installed, the channel 2 BNC connector’s outer shell is connected to chassis
ground. If option AY5 (precision frequency reference) is installed, the oven
reference output BNC connector’s outer shell is connected to chassis ground.
Warning DO NOT interrupt the protective earth ground or ‘’float’’ the
Agilent 89410A DC-10 MHz Vector Signal Analyzer. This action could
expose the operator to potentially hazardous voltages.
The analyzer is equipped with a three-conductor power cord that grounds the
analyzer when plugged into an appropriate receptacle. The type of power cable
plug shipped with each analyzer depends on the country of destination. The
following figure shows available power cables and plug configurations.
