4.5.13 Power Measurements – MEAS Key
With its power measurement functions the R&S FSQ is able to measure all the necessary
parameters with high accuracy in a wide dynamic range.
A modulated carrier is almost always used (except e.g. SSB-AM) for high-frequency
transmission of information. Due to the information modulated upon the carrier, the
latter covers a spectrum which is defined by the modulation, the transmission data
rate and the signal filtering. Within a transmission band each carrier is assigned a
channel taking into account these parameters. In order to ensure error-free transmission,
each transmitter must be conforming to the specified parameters. These
include among others:
• the output power,
• the occupied bandwidth, i.e. the bandwidth which must contain a defined
percentage of the power and
• the power dissipation allowed in the adjacent channels.
Additionally the menu contains functions to determine the modulation depth of AM
modulated signals and to measure the 3rd order intercept point.
The measurements and the corresponding settings are selected in the MEAS menu.
