Analyzing Data
Bandwidth Search
6. Analyzing Data
Bandwidth Search
The E5061A/E5062A has a feature called Bandwidth Search. This feature searches for the
cutoff points on both right- and left-hand sides of the marker position on the trace.
R Bandwidth ( )
R Center frequency ( )
R Q value ( )
R Loss (response value at the marker position)
Where is the right-hand cutoff point frequency; is the left-hand cutoff point
frequency.
Setting the Bandwidth Definition Value
Bandwidth Search finds a point whose response value is different, by the amount defined
as the bandwidth definition value, than the response value at the marker position, and
identifies that point as the cutoff point.
To set the bandwidth definition value, use the following command:
• :CALC{1-4}:MARK{1-10}:BWID:THR on page 266
Retrieving Bandwidth Search Results
Once you have moved the marker to the appropriate position using Marker Search or some
other feature, you can retrieve the results of Bandwidth Search using the following
command:
• :CALC{1-4}:MARK{1-10}:BWID:DATA? on page 265
Also, you can use the following command to control whether to display the results of
Bandwidth Search on the LCD:
• :CALC{1-4}:MARK:BWID on page 243
NOTE You can retrieve the results of Bandwidth Search even after you have turned off the display
of markers or the results of Bandwidth Search.
Sample Program
Example 6-2 shows a sample program that demonstrates how to perform Bandwidth
Search. You can find the source file of this program, named bandwid.htb, on the sample
program disk.
The sample program moves the marker to the maximum value position, then retrieves and
displays the results of Bandwidth Search.
The program is described in detail below:
Line 50 Assigns a GPIB address to the I/O pass.
Line 60 Stores a bandwidth definition value of 3 into the Threshold variable.
