Fast Device Tune Measurement
E1999A-202 FDT Enhanced
Fast device tune measurement
Input frequency ranges
Measurement method
411 to 420 MHz
450 to 484 MHz
821 to 934 MHz
1700 to 1980 MHz
Allows user definition of an RF source power output sequence
simultaneously with a Tx power measurement sequence each consisting
of 10 or 20 ms duration steps with user-defined step size. Sequence
can be defined to repeat over a number of frequencies inside of a single
frequency band. This measurement requires a test mode in the mobile
station in order to operate. Measures the total power in a 1.23 MHz
bandwidth centered on the active reverse channel center frequency in
each step period
