Port/Sweep
Port/Sweep
This control performs two functions:
• The upper field specifies the output port of the tracking generator.
• The lower field specifies whether the tracking generator sweeps from
low-to-high frequencies (
Norm
), or from high-to-low frequencies
(
Invert
). (The spectrum analyzer always sweeps from low to high
frequencies.) The swept frequency range is determined by the
Span
setting in the spectrum analyzer’s main controls menu.
This field is displayed only when
Track
is selected in the
Track/Fixed
field on the spectrum analyzer’s
RF Gen
controls menu.
Operating Considerations
When using the tracking generator, if the output port is set to
RF Out
,
or the main menu
Input Port
is set to
RF In
, internal instrument
coupling can occur. For the best isolation between the tracking
generator and the spectrum analyzer, use
generator and the spectrum analyzer, use
Dupl
for the output, and
Ant
for the input.
For measurements on high-power devices, such as amplifiers, use the
RF IN/OUT port for the input.
RF IN/OUT port for the input.
