Frequency/Phase Modulation (Option 12)
Option 12 adds frequency and phase modulation, driven externally
via a rear panel BNC connector, 50
Ω
. For internal modulation, add
LF Generator Option 23. Frequency/Phase Modulation is not
available <10 MHz with Option 22.
For most accurate FM,
Φ
M
measurements, Bessel Null methods are
used.
