What is the maximum deviation from the reading 462,100,000 Hz on a frequency counter with a time-base accuracy of ±1.0 ppm?

Explanation:
Time-base accuracy of ±1.0 ppm means the counter’s clock can introduce an error up to one part in a million of the measured value. To find the maximum Hz deviation, multiply the reading by 1×10^-6. For 462,100,000 Hz, that is 462,100,000 × 0.000001 = 462.1 Hz. So the maximum deviation from the reading is ±462.1 Hz. The other magnitudes would not match the actual ppm-based error at this frequency.
