Basic Discrete PAvT Measurement SCPI Commands
The Basic Discrete PAvT measurement requires the following parameters to be specified:
• Filter Type
• Interval Count
• Interval Centers
• Interval Widths
The following commands are used to set up these parameters:
[:SENSe]:LSEQuencer:PCALibration:FILTer WIDE|NARRow|VNARrow|ENARrow
[:SENSe]:LSEQuencer:PCALibration:STEP:COUNt <integer>
[:SENSe]:LSEQuencer:PCALibration:STEP:CENTer <time>, ...,< time >
[:SENSe]:LSEQuencer:PCALibration:WIDTh <time>, ...,< time >
For more detailed information about the SCPI commands above refer to the Sequence Analyzer online
help (or in pdf format, the User’s and Programmer’s Reference).
Basic Discrete PAvT Results
The parameters and default setting for this command are detailed in the following table. The first SCPI
parameter is Index 0.
Index Result Parameter
0 Number of steps to be measured.
1 Returns a 512 length list of comma-separated values for the amplitude of each
step. The first step amplitude result is absolute value. The results of other steps
are referenced to the first step and they are relative value.
2 Returns a 512 length list of comma-separated values for the phase error of each
step. The first step phase error result is as the zero. The results of other steps are
referenced to the first step phase.
3 Returns a 512 length list of comma-separated values for the frequency error of
each step. The first step frequency error result is referenced to the frequency set
of the acquisition. The results of other steps are referenced to the first step
frequency error result.
