■ [SWEEP ITEM]
: Set the sweep item.
This selects the parameter to sweep. The parameter set here becomes the X-axis of the
graph.
○ Setting procedure
<List operations (immediate settings)>
・
FREQUENCY
: Sweep the frequency.
・
AMPLITUDE
: Sweep the measurement signal amplitude.
・
DC BIAS
: Sweep the DC bias.
・
ZERO−SPAN
: Keep the measurement conditions constant (zero-span sweep).
■ [SWEEP UPPER]
: Set the sweep upper limit.
■ [SWEEP LOWER]
: Set the sweep lower limit.
This sets the upper and lower limits of the range for performing sweep measurements.
○ Setting procedure
<Numerical settings (immediate settings)>, <Numerical settings>
When a frequency sweep is performed, the range is 10 µHz to 36 MHz (resolution of 10 µHz).
When an measurement signal amplitude sweep or a DC bias sweep is performed, the setting
range differs depending on the DUT drive amplifier gain setting (set based on the AC
amplitude or DC bias applied to the DUT). Furthermore, there is the limitation of lower limit
< upper limit. When a zero-span sweep is performed, this setting is not applied (it is
disabled).
○ Functions of function keys
・
[MKR -> SWEEP]
: Set the smaller and larger of MARKER1 and MARKER2 to
LOWER and UPPER, respectively.
・
[GRAPH -> SWEEP]
: Set the current graph X-axis range to the sweep range.
・
[MKR -> UPPER]
: Set the value of the active marker as the sweep upper limit.
・
[MKR -> LOWER]
: Set the value of the active marker as the sweep lower limit.
・
[EDIT]
: Set the sweep upper limit and lower limit with the numerical
input palette.
・
[MODIFY]
: Modify the sweep upper limit and lower limit with the knob or
cursor keys.
