Powers expressed in dBm, dynamic port separation SD expressed in
dB.
SD = P - D
step chng
Conditions: Power step height as specified (1 mW).
Power range
Specifies the range from the smallest input power that causes a
significant change of the measured (displayed) power to the highest
power for which the specifications apply if not differently stated.
Range settling time (one range step)
When changing from one power meter range to the next (one range
higher or lower), the settling time specifies the time required for the
power meter to settle into the new range. Measurements starting after
that period are within specifications.
The time starts when the instrument receives the range change
command (manual range) or when the instrument detects the
requirement for power meter range change (autorange).
Conditions: As specified.
Relative port to port uncertainty
Specifies ± half the maximum difference between the measured powers
of different ports when applying the same stimulus. Measured powers
expressed in dBm, the relative port to port uncertainty U expressed in
±dB.
