3.5.3 Sweep dialog
■ [SEQ SWEEP]
: Set sequence measurement.
This function performs measurements in the order set in the setting memory of the instrument. It is
possible to do measurements at different signal levels for each frequency range. For more information in
sequence measurements, refer to "
5.11 Sequence measurement
".
○ Setting method
< List operations (confirming) >
• OFF, 1 to 20
: No sequence measurements, or 1 to 20
■ [SWEEP LOWER] / [SWEEP UPPER]
: Set the upper and lower sweep frequencies.
This sets the frequency range for performing sweep measurements.
○ Setting method
< Numerical value settings (immediate setting) >, < Numerical value settings (new input) > ,
< Numerical value settings (edit) >
The setting range is from 10 µHz to 15 MHz and the resolution is 10 µHz. The lower frequency limit
must be less than the upper frequency limit.
○ Function key functions
• [MKR -> SWEEP]
: Set the frequency of the main marker and the delta marker to the range
of the sweep frequency.
• [GRAPH -> SWEEP]
: Set the sweep frequency range to the range of the X axis (frequency
range) of the graph.
• [MKR -> FREQ]
: Copy the main marker frequency to the sweep lower frequency limit
(for
[SWEEP LOWER]
) or to the upper frequency limit (for
[SWEEP
UPPER]
).
• [DIRECT NEW]
