Vector Modulation Analysis
(Option 89601A-AYA)
Note that analysis and presets are
only valid over the frequency range
of the N4010A-101/102.
Signal acquisition
Note: Signal acquisition does not require
an external carrier or symbol clock
Data block length Adjustable to 4096 symbols
Samples per symbol 1 – 20
Symbol clock Internally generated
Carrier lock Internally locked
Triggering Single/continuous, external, pulse search
(searches data block for beginning of TDMA burst
and performs analysis over selected burst length)
Data synchronization User-selected synchronization words
Supported modulation formats
Carrier types Continuous and pulsed/burst (such as TDMA)
Modulation formats 2, 4, 8, and 16 level FSK (including GFSK)
