Programming Examples
Example 27: Delay T able Operations
This example demonstrates ho w to input, output and apply table dela y . The dela y table is
also stored and loaded using the net w ork analyzer in ternal disk.
Example 28: F ast CW Data Acquisition
F ast CW setup and op eration is demonstrated using an external trigger source. Once the data
is collected, it is con v erted from F ORM1 to real/imaginary data pairs.
Example 29: T est P ort P o w er Flatness Cal
T est p ort p o w er atness cal can b e p erformed only on a system using an 8360 Series source.
If y our system uses an 8350 or 8340 Series source, y ou m ust skip this example. A prop erly
addressed p o w er meter m ust also b e connected to the 8510C net w ork analyzer system bus.
After zeroing the p o w er sensor, the user is prompted to connect it to p ort 1 on the test set.
The calibration measures the p o w er from 2 GHz to 20 GHz, compares the measured p o w er
to the source p o w er setting, and calculates a p o w er oset factor to obtain lev eled p o w er at
the p ort. This correction arra y is stored in the source and applied to its output p o w er when
atness is turned ON. When p o w er atness is ON, the v alue display ed or en tered for source
1 p o w er is the p o w er at the test set p ort 1. With atness OFF, it is the p o w er at the source
output.
Example 30: Receiv er P o w er Cal/P o w er Domain
Note
Receiv er calibration and p o w er domain require 8510C rm w are Rev. C.07.00
or greater.
This example p erforms a receiv er calibration, whic h then allo ws the 8510C to display
unratio ed p o w er measuremen ts of the input and output p o w er of a device connected b et w een
p orts 1 and 2 on the test set, calibrated in dBm. A test p ort p o w er atness cal, v alid from
2 GHz to 20 GHz, m ust ha v e b een p erformed b efore running this example. If y ou need to do a
atness calibration, run Example 29. When the calibration is nished, the display sho ws input
p o w er on c hannel 1 and output p o w er on c hannel 2. The marker readout is calibrated in dBm.
Next, p o w er domain is sho wn. The receiv er cal p erformed in the frequency domain is
con v erted automatically for use in p o w er domain, as long as the frequency of the measuremen t
is at a p oint in the original frequency domain cal. A v alid frequency may b e selected b y
placing a marker on the frequency p oint b efore en tering p o w er domain. The marker frequency
is used as the frequency of measuremen t when p o w er domain is selected. Once in p o w er
domain, the

frequency-of-measuremen t that is v alid for the calibration.
