The U3606B takes a measurement and calculates the power delivered to a reference resistance (typically 50 Ω, 75 Ω, or 600 Ω). Voltage measurement is then converted to dBm. NOTE This math operation applies to voltage measurements only.
U3606-90054_UG_EN.book Page 67 Friday, July 11, 2014 5:12 PM Operation and Features Math Operations 2 dB measurements Each dB measurement is the difference between the input signal and a stored relative value, with both values converted to dBm. When enabled, the dB operation computes the dBm value for the next reading, stores the dBm result into the relative value register, and immediately produces the dB calculation.
