Test Procedure: a^ Switch on the test equipment and allow sufficient time for warm-up and stabilization. K Perform verification. Apply calibrated signal levels at 1 kHz, 3 kHz, and 10 kHz to the current probe. The signal levels shall be 6 dB below the applicable limit. c> Measure the current level using an oscilloscope and a resistor; verify that the current waveform is sinusoidal. d^ Scan the measurement receiver in the normal data scan mode. Verify that the receiver reading is within ±3 dB of the current level measured by the oscilloscope. If the deviation exceeds ±3 dB, locate the source of...
