LF Generator and LF Output - Mod Gen Block
An LF generator providing sinusoidal signals in the frequency range 0.1 Hz to 1 MHz is available for the
basic unit without additional equipment options.
The internal LF generator is the internal source for the analog modulations AM and FM / PhiM, and as
the signal source for the LF output at the front of the instrument.
The LF generator settings can be made both in the modulation menus and in the LF Output menu. The
settings are effective for all modulations using the internal modulation source. For example, a change to
the frequency of the LF generator automatically has an effect on AM modulation if internal source is
selected as the AM modulation source (i.e. Int is selected as Source).
The LF Sweep mode is activated in the LF Sweep menu. RF frequency and level sweeps are activated
in the respective menus of the RF block.
The internal pulse gnenerator enables the generation of single and double pulse signals. The generator
is activated and configured in the Pulse Generator menu of the LF output block or in the Pulse
Modulation menu of the Mod block (Pulse Generator is selected as Source).
LF Frequency Sweep Menu
The LF Frequency Sweep menu is opened in the Mod Gen function block or using the SETUP key
under LF Gen.
In the top section, the LF Sweep mode is activated and the sweep mode is selected. The buttons are
used to reset the LF sweep (all sweep modes) or to execute the LF sweep (Single mode).
