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 861
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 867
SOURce<n>:FM:DEViation on page 867
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 862
Modulation OFF ← Modulation
Deactivates external modulation of the tracking generator output signal.
Remote command:
SOURce<n>:AM:STATe on page 861

SOURce<n>:FM:STATe on page 867
Power Sweep
Opens a submenu to define power sweep settings.
This softkey is only available if the (internal) Tracking Generator option (B9) is instal-
led.
This submenu contains the following commands:
●
"Power Sweep (On /Off)" on page 478
●
"Power Sweep Start" on page 479
●
"Power Sweep Stop" on page 479
Power Sweep (On /Off) ← Power Sweep
Activates or deactivates the power sweep. If the power sweep is on, the analyzer is set
to zero span mode (span = 0Hz). During the sweep time of the zero span, the power at
the internal tracking generator is changed linearly from start power to stop power. The
start and stop power for the power sweep are displayed in the diagram header ("INT
TG <start power>… <stop power>", see also Chapter 3.6.5, "Displayed Information
and Errors", on page 498.
