This value could be any one of the
following:
l
The start frequency of the source in frequency domain
measurements.
m
The start time in CW mode (0 seconds) or time domain
measurements.
n
The lower power value in power sweep.
When the stimulus is in center/span mode, the center stimulus
value is shown in this space.
Stimulus Stop
2.
Value.
This value could be any one of the
following:
m
The stop frequency of the source in frequency domain
measurements.
m
The stop time in time domain measurements or CW sweeps.
l
The upper limit of a power sweep.
When the stimulus is in center/span mode, the span is shown in
this space. The stimulus values can be blanked.
(For CW time and power sweep measurements, the CW frequency
is displayed centered between the start and stop times or power
values.)

frequency reference signal input that can phase lock the analyzer
to an external frequency standard for increased frequency
accuracy.
The analyzer automatically enables the external frequency
reference feature when a signal is

the signal is removed, the analyzer automatically switches back to

This allows for a dc or ac voltage

Basic Measurement Sequence and Example
Basic Measurement Sequence
There are Eve basic steps when you are making a measurement.
1. Connect the device under test and any required test equipment.
2. Choose the measurement parameters.
3. Perform and apply the appropriate error-correction.
4. Measure the device under test.
5. Output the measurement results.
Basic Measurement Example
In the following example, a magnitude and insertion phase response
measurement is made.
Step 1. Connect the device under test and any required test
equipment.
