6.10.1 Improvement of Measurement Efficiency by Measurement Setting
In order to improve the measurement efficiency of the DUT requiring various parameter measurements, you should
be familiar with the analyzer operation, which can help to create the optimal application solution. See trace,
channel and window details related to parameter measurements in “
3.4 Track, Channel and Window of Analyzer
”.
1) Reasonably arrange one group of measurements.
Arrange one group of measurements of the DUT in one instrument state. Save the instrument state so as to perform
the previous group of measurements by recalling. Or, arrange a group of measurements by the preconfigured
measurement setting function of the analyzer. See details in “
Setting of preconfigured measurement
” of “
4.8
Observation of multiple traces and opening of multiple channels
”.
2) Apply the segment sweep function.
Segment sweep can be applied to change the following settings to represent multiple parameter measurements of
one device.
➢
Frequency range
➢
power level
➢
intermediate-frequency bandwidth
➢
Number of sweep point
A group of frequency ranges with respective attributes can be defined in segment sweep. In this case, the DUT with
multiple measurement settings can be measured by means of one sweep. See segment sweep details in the “
Setting
of segment sweep type
” of “
4.5.2 Setting of sweep type
” of “
4.5 Setting of sweep
”.
3) Selectively trigger the measurement.
Set the measurement as follows by triggering.
➢
Continuously update the measurement with rapid data changes.
➢
Occasionally update the measurement with a few data changes.
For example, the tuning measurement of one filter can be set by the following settings:
➢
One channel is used to measure the passband response of the filter in tuning.
➢
One channel is used to measure the out-of-band response of the filter.
In this case, the turning measurement of the filter can be observed continuously. If all channels are updated
constantly, the response velocity of the analyzer will be reduced, and the filter cannot be tuned rapidly.
Measurement setting is introduced as follows.
➢
Measurement data of Channel 1 will be updated continuously.
➢
Measurement data of Channel 2 will be updated when required.
a) Use the mouse.
1) Create the double-channel measurement.
Menu path: [Response] > [Display] > [Measurement Setup] > [Setting D] .
2) Set the trigger mode of Channel 1: constantly update measurement data.
Menu path: [Stimulus] > [Trigger] > [Trigger...] . The [Trigger] dialog box will appear.
Select the [Internal] radio box in the trigger source zone.
