Save As Trd Factor ← Source Cal
Uses the normalized measurement data to generate a transducer factor with up to 625
points. The trace data is converted to a transducer with unit dB and stored in a file with
the specified name and the suffix.trd under "
c:\r_s\instr\trd
". The frequency
points are allocated in equidistant steps between start and stop frequency. The gener-
ated transducer factor can be further adapted using the "Transducer" softkey in the
"SETUP" menu.
The "Save As Trd Factor" softkey is only available if normalization is switched on.

Modulation
Opens a submenu to define modulation settings. This submenu contains the following
commands:
●
"External AM" on page 479
●
"External FM" on page 479
●
"External I/Q" on page 479
●
"Modulation OFF" on page 479
External AM ← Modulation
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 active I/Q modulation.
Remote command:
SOURce<n>:AM:STATe
on page 903
External FM ← Modulation
Activates the FM modulation of the tracking generator output signal. The modulation
signal is applied to the TG IN Q/FM connector. Switching on an external FM disables
the active I/Q modulation.
Remote command:
SOURce<n>:FM:STATe
on page 904
SOURce<n>:FM:DEViation
on page 904
External I/Q ← Modulation
Activates the external I/Q modulation of the tracking generator output signal. The sig-
nals for modulation are applied to the two input connectors TG IN I and TG IN Q at the
rear panel of the unit. The input voltage range is ±1 V into 50
Ω
. Switching on an exter-
nal I/Q modulation disables the active AM or FM modulation.
Remote command:
SOURce<n>:DM:STATe
on page 903
Modulation OFF ← Modulation
Deactivates external modulation of the tracking generator output signal.
