R3131 Spectrum Analyzer Operation Manual
1.3 Operating Environment
1.3.4 Power Cable
A detachable power cable with a three-contact plug is included with the spectrum analyzer. The protective
earth ground contact on the plug connects (through the power cable) to the accessible metal parts of the
instrument. For protection against electrical shock, insert the plug into a power-source outlet that has a
properly grounded, protective-ground contact.
The manufacturer ships a power cable, as ordered, with the spectrum analyzer. A list of other available
power cables is shown in Table 1-2. Contact a sales representative for information on how to order these.
