Correction Based on User-Specified Frequency Points
Description of Correction Based on User-Specified Frequency Points
Correction based on user-specified frequency points involves performing
open/short/load correction at frequency points specified by user. You can
specify up to 201 frequency points as needed.
For examples and instructions on using the correction features, see “Correction
Functions” on page 208.
In addition to the open/short correction features, the E4980A/AL provides a
load correction feature that allows you to carry out, at your specified frequency
points, load correction using a transfer function determined based on the
relationships between a particular standard’s reference values (pre-measured,
known values) and the standard’s actual measurements. With load correction,
you can compensate for errors that cannot be compensated using open/short
correction.
Open/short/load correction can be performed at up to 201 specified frequency
points, as shown in Figure 4-12. You can define these frequency points using
the SPOT No. fields. To specify the standard’s reference values, use the A and B
fields. Before entering the standard’s reference values, you need to set the
measurement function using the FUNC field. To obtain the standard’s actual
measurements, use the softkey, which appears when you move the cursor into
the FREQ field.

To specify frequency points and carry out open correction:
Step 1. Press [Meas Setup].
Step 2. Press the CORRECTION softkey.
Step 3. Using the cursor keys, select the SPOT No. field.
Step 4. Enter the measurement point number using the softkeys or entry keys. If you
have used the entry keys to enter the value, the softkey labels change to unit
labels (x1).
