Using Time as Sweep Parameter (Zero Span Sweep)
Using Time as Sweep Parameter (Zero Span Sweep)
Setting the sweep span to zero allows you to perform a measurement with time as a sweep
parameter. This kind of sweep is also called zero span sweep.
Step 1. Press the
[Sweep] key to display the sweep menu.
Step 2. Press the
PARAMETER [ ] key to display the sweep parameter menu.
Step 3. Press the
FREQ key to select frequency as a sweep parameter.
Step 4. Press the [Span] key. This will display the current setting for sweep span value in the
parameter settings area in the upper-left part of the screen.
Step 5. Press
[0] - [´1] to set the sweep span value to zero.
Step 6. Press the
[Center] key. At this point, the value displayed in the parameter settings area in
the upper-left part of the screen shows that the signal source used has a fixed, not swept,
frequency.
Step 7. Use the keys or the rotary knob in the ENTRY block in one of the following ways to set the
fixed frequency displayed on the screen.
• Enter the desired value with the numeric keys (
[0] to [9], [.], and [-]) and then press one
of the unit keys (
[G/n], [M/m], [k/m], or [´1]).
• Turn the rotary knob (
m
mm
m) until the desired value is set.
• Press the step keys ([][¯]) to set the desired value.
Step 8. Press the
[Sweep] key to display the sweep menu.
Step 9. Press the
TIME key to display the sweep time menu.
Step 10. Press the SWEEP TIME key. This will display the current setting for sweep time in the
parameter settings area in the upper-left part of the screen. In other words, this shows the
current sweep span value in the time sweep.
Step 11. Use the keys or the rotary knob in the ENTRY block in one of the following ways to
specify a value for the sweep time (sweep span).
• Enter the desired value with the numeric keys (
[0] to [9], [.], and [-]) and then press one
of the unit keys (
[G/n], [M/m], [k/m], or [´1]).
• Turn the rotary knob (
m
mm
m) until the desired value is set.
• Press the step keys ([][¯]) to set the desired value.
NOTE Sweep time (sweep span value) can be set up to 10,000 seconds (approx. 2.8 hours).
When using a marker immediately after setting the zero span sweep from the preset state,
the sweep parameter value shown by the marker in the parameter settings area in the
upper-left part of the screen is indicated by a measurement point number (serial number s
from 1 to the number of points for all measurement points). At the same time, an identical
value entered with the
[Center] key for all measurement points is indicated in the marker
sweep parameter area in the upper-right part of the screen. This sweep parameter value can
be converted into a time-based value for display by pressing the
