Calibrating for Increased Measurement Accuracy
Adapter Removal Using ECal (ES Analyzers Only)
Determine the Electrical Delay
This procedure determines the electrical delay of adapter A3 using a short.
1. Refer to Figure 6-29 while performing the steps in this procedure.
2. Perform a 1-port calibration at “Reference Port 1”. Refer to Step A of Figure 6-29.
This 1-port calibration can either be a manual calibration or an ECal.
Figure 6-29 Determining the Electrical Delay Setup
3. Connect the A3 adapter to “Reference Port 1” as shown in Step B of Figure 6-29.
Connect a short to the open end of the A3 adapter.
4. Measure the delay of the adapter by pressing .
5. Divide the resulting delay measurement by 2 to determine the delay of the thru and the
short in one direction.
6. Determine the offset delay of the calibration short by examining the define standard
menu (see "Define Standard Menus" on page 7-59).
7. Subtract the offset delay of the short (determined in step 6) from the delay of the thru
and the short in one direction (determined in step 5). The result is electrical delay of the
thru. This value is used in the next procedure.
