Note
Channels 1 and 2 are power meter channels and make power measurements
directly. Power is expressed in logarithmic units as decibel milliwatts or dBm.
Power is also expressed in linear units as nanowatts, microwatts, milliwatts,
watts, kilowatts and Megawatts as appropriate. Voltage units are derived from
power values as the equivalent voltage across a 50 ohm load. Derived voltage
is expressed in logarithmic units as decibel microvolts, decibel millivolts and
decibel volts. Derived voltage is also expressed in linear units, including
microvolts, millivolts, volts and kilovolts.

Peak Hold Pulse & Mod Turns Peak Hold function on and off
(Toggle) Off, On
The Peak Hold function is used to hold peak
measurement values until reset. When Peak
Hold is Off, the measured peak values decay
at a rate set by the Averaging function.
