Q

What is the most the actual transmitter frequency could differ from a reading of 156,520,000 hertz on a frequency counter with a time base accuracy of ± 1.0 ppm?

🔍 Key Concepts

• Parts per million (ppm) as a way to express frequency tolerance • How to calculate the frequency error using ppm × carrier frequency • Converting between hertz (Hz), kilohertz (kHz), and megahertz (MHz)

💭 Think About

• First, rewrite 156,520,000 Hz in megahertz (MHz). What value do you get? • What is 1.0 ppm as a decimal (e.g., 0.000001)? Multiply that by the carrier frequency to get the maximum error in hertz. • After finding the error in hertz, which answer choice has the same order of magnitude and unit?

✅ Before You Answer

• Verify that 1 ppm = 1 × 10⁻⁶ of the carrier frequency. • Double-check your unit conversions: 1 kHz = 1,000 Hz; 1 MHz = 1,000,000 Hz. • Confirm that you’re using the carrier frequency in the same units when applying the ppm value (convert everything consistently).
