The most the actual transmit frequency could differ from a reading of 462.1 MHz on a frequency counter with time-base accuracy ±0.1 ppm?

Time-base accuracy limits how far a frequency counter’s reading can be off from the true frequency. With a reading of 462.1 MHz and a time-base accuracy of ±0.1 ppm, the maximum error is the frequency times 0.1 × 10^-6. 462.1 MHz is 462.1 × 10^6 Hz. Multiplying by 0.1 × 10^-6 gives 462.1 × 10^6 × 1 × 10^-7 = 46.21 Hz. So the most the actual transmit frequency could differ from the reading is 46.21 Hz (approximately 46 Hz).
