R&S ESCI Tracking Generator - Option R&S FSP-B9
1166.6004.12 4.285 E-1
EXT AM
The EXT AM softkey activates an AM modulation of the tracking generator
output signal.
The modulation signal is applied to the TG IN I / AM connector. An input
voltage of 1 V corresponds to 100% amplitude modulation.
Switching on an external AM disables the following function:
– active I/Q modulation.
IEC/IEEE-bus command: SOUR:AM:STAT ON
EXT FM
The EXT FM softkey activates the FM modulation of the tracking generator
output signal.
The modulation frequency range is 1 kHz to 100 kHz, the deviation can be
set in 1-decade steps in the range of 100 Hz to 10 MHz at an input voltage
of 1 V. The phase deviation η should not exceed the value 100.
Phase deviation η = deviation / modulation frequency
The modulation signal is applied to the TG IN Q / FM connector.
Switching on an external FM disables the following function:
– active I/Q modulation.
IEC/IEEE-bus command: SOUR:FM:STAT ON
SOUR:FM:DEV 10MHz
