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 which
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.
