Setting Stimulus Conditions
Setting the number of points
The number of points is the number of data items collected in one sweep. It can be set to
any number from 2 to 1601 for each channel independently.
•
To obtain a higher trace resolution against the stimulus value, choose a larger number
of points.
•
To obtain higher throughput, keep the number of points to a smaller value within an
allowable trace resolution.
•
To obtain higher measurement accuracy after calibration, perform calibration using the
same number of points as in actual measurements.
NOTE
When the upper limit of the number of channels and traces is set to
1Ch / 4 Tr 20001
Points
in Channel/Trace Setup, the maximum number of measurement points will be
20001.
Setting the number of points
Step 1.

Step 4.
Using the ENTRY block keys on the front panel, input the desired number of points.
Setting the sweep time
Sweep time is the time it takes to complete a sweep for each stimulus (source) port. Two
modes are available for setting the sweep time: manual sweep time mode and automatic
sweep time mode.
Manual Sweep Time Mode
In this mode, the sweep time is set manually. Once the sweep
time is set, changes in measurement conditions will not affect
the sweep time as long as it is within the analyzer's capability.
If the sweep time becomes lower than the analyzer’s lower
sweep time limit, the sweep time will be reset to the shortest
time within the conditions. If the sweep time exceeds the
analyzer’s upper sweep time limit, the sweep time will be
reset to the longest time within the conditions.
Automatic Sweep Time Mode
The sweep time is always kept to the shortest time possible
with the current measurement conditions.
Figure 3-7 shows the definitions of the sweep time and the sweep delay time.
