  • Page 46 When a system under test is not connected to the ground, the potential of the signal ground fluctuates, the FRA5014’s dielectric insulation voltage may be exceeded or common mode noise may occur, which can adversely affect measurements. If this is suspected, use an oscilloscope (etc.) to check the signal ground’s potential.

  • Page 47: Figure 4-2. Examples Of Expanded Measurement Voltage Range

    ◼ Expansion of measurement voltage range The FRA5014’s built-in oscillator has 42 Vpk of dielectric insulation voltage relative to the case. This means that in a circuit where the potential is about 40 V, signals can be injected directly. By contrast, the analyzer’s input voltage range is limited to 10 V. If the signal exceeds this range, direct measurements become impossible.

    For description of query commands, 7.5 Checking Isolation The FRA5014’s oscillator output and analyzer input should each be insulated from the case. Using a resistance meter (tester, multimeter, etc.), measure the resistance between the external conductors on the rear panel’s BNC connectors and the grounding terminal in the center of the rear panel, and make sure it is at least 10 MΩ.
