Long Blanking - of a List Point
The Long Blanking (also referred to as long switch/blanking time) check
box, available from the Soft Front Panel, is used to specify that the
switch/blanking time for the currently selected list point be set to
350 us. When this check box is selected, an L is displayed under the
Flags column of the List Dialog Box.
Selecting the Long Blanking check box is different from selecting the
Blanking check box. Selecting the Long Blanking check box does not
specify that the RF output be blanked; it only specifies that the
switch/blanking time be set to 350 us. If RF output blanking is also
desired, the Blanking check box must be selected.
• If the RF output is being blanked, the RF output is turned off during
the switch/blanking time. Although the RF output can be optionally
blanked when changing frequency or power or both, it is always
blanked when the 10 dB step attenuator (Option 1E1) is changed.
• If the RF output is not being blanked, the RF output is turned on
during the switch/blanking time and may be affected by spurious
signals, harmonics, or other glitches.
Whether or not the RF output is turned off (blanked), there is always a
switch/blanking time. Switch/blanking time is the period of time, prior
to the user-definable settling time, that is required by the synthesizer
to change between frequencies or power or both. Switch/blanking time
can not be turned off.
