Example 6: Frequency-Dependent Offsets
The frequency-dependent offset (FDO) feature provides you with a convenient way
to store the offset values in a handy table. Multiple FDO tables can be created to
compensate for different external test setups with different frequency responses.
By enabling the FDO table during measurement, the pre-entered offset values will
be retrieved to compensate for your external test setup over a range of
frequencies.
The following command sequence provides a simple example to create an FDO
table, assign an offset for a frequency value, store the table under your preferred
name, and turn on the table for measurement use.
-> MEM:TABL:SEL "CUSTOM_A"
-> MEM:TABL:FREQ 50MHz
-> MEM:TABL:GAIN 50
-> CORR:CSET2 "CUSTOM_A"
-> CORR:CSET2:STAT 1
-> FREQ 1000MHz
-> FETC?
"–>" indicates the commands that you send to the N432A.
NOTE
"<–" indicates the response from the N432A.
Keysight N432A Programming Guide
Programming Examples
// Selects an FDO table named
"CUSTOM_A".
// Enters a frequency of 50 MHz into the
selected table.
// Enters an offset factor of 50% into the
selected table.
// Enters the name of the selected table.
// Enables the selected table.
// Sets the frequency to 1000 MHz.
// Queries the measurement result. The
above sequence must be followed.
