If a measurement frequency does not correspond directly to a frequency in the sensor
N O T E
calibration table (if selected) and the frequency-dependent offset table being used, the
N432A calculates the calibration factor and offset using linear interpolation.
If you enter a frequency outside the frequency range defined in the sensor calibration table
or the frequency-dependent offset table, the N432A uses the highest or lowest frequency
point in the appropriate table to set the calibration factor and offset.
Editing the frequency-dependent offset table
There are 10 frequency- dependent offset tables named CUSTOM_A through
CUSTOM_J. They are empty of any data when the N432A is shipped from
the factory.
You cannot delete any of the 10 existing frequency- dependent offset tables
or create any additional tables. However, you can enter values into the 10
existing tables. Each frequency- dependent offset table can contain a
maximum of 80 frequency points.
To view the frequency- dependent offset tables currently stored in the
N432A, press
Editing the offset tables requires the following steps:
1 Identify and select the table you want to edit
2 Rename the table
3 Enter the frequency and offset pairs
4 Save the table
Procedure
First, select the table you want to edit as follows:
A frequency in the range of 0.001 MHz to 1000.0 GHz can be entered. An offset in the range
N O T E
of 0.00000001% to 1000000000000% can be entered.
