855xxA/B Series CalPods and 85523B CalPod Controller Usage Information
Method 2: Using the mouse and the PNA pull-down menus.
Click Response > Cal > Start Cal > Cal Wizard.
•
Follow the prompts in the calibration wizard to complete the calibration
•
Select Save as User CalSet. Any file name that does not contain “calpod” may be used.
You must select
Save as User CalSet
(rather than “Finish”) to save the
calibration in the channel 1 cal register.
After completing the calibration, do not disturb any of the measurement hardware,
until “Step 1
0 . Initialize the CalPods” is completed, and the Initialize Channel
operation has been performed on the CalPods. During this operation, the CalPods
make a measurement requiring the same measurement hardware to properly
initialize the CalPod correction arrays.
Step 10. Initialize the CalPods
Without disturbing any of the measurement hardware, use either of the following methods to save the
initial calibration into the CalPod correction array. This must be done immediately after completing
the last step of the initial calibration.
Method 1: Using the PNA front panel HARDKEYs and [softkeys].
Press CAL > [More] > [Calpod] > [Initialize Channel]
Method 2: Using the mouse and the PNA pull-down menus.
Click Response > Calpod > Initialize Channel
The calibration correction array established by the initial calibration is transferred to the CalPod
correction array in this step. Any disturbances of the measurement hardware (such as cable
movements) prior to performing the Initialize Channel step will affect the quality of the recorrection
array.
IMPORTANT Do not Initialize Channel at any future point in time or the recorrection array will
be corrupted, causing improper recorrections and inaccurate measurement data.
Step 11. Configure the Hardware for a Measurement
After the Initialize Channel procedure is completed, as detailed in the previous step, the
measurement hardware can be reconfigured. For example, the short, stable cable between PNA
port 1 and the CalPod can be replaced with a longer cable to reach a CalPod and DUT located
inside a temperature or TVAC chamber. Other modifications in the path between the PNA and
the CalPod – such as different adapters, and even switch matrices – can now be made.
Step 12. Recorrect (Refresh) the CalPods
When a calibration refresh is performed, the initial calibration is reestablished at the new
location of the CalPods.
