CURSOR - PARAMETER_VALUE?, PAVA?
Description
The PARAMETER_VALUE query returns the current values of the pulse waveform parameters
and mask tests for the specified trace. Traces do not need to be displayed or selected to obtain
the values measured by the pulse parameters or mask tests.

Query Syntax
<trace>:PArameter_VAlue? [<parameter>,...,<parameter>]
<trace>:=
{
TA,TB,TC,TD,C1,C2,C3,C4}
NOTE: When PAVA? Is used to query a Custom parameter, the prefix is returned for
consistency. However, the source for the measurement is the one configured using the
PACU command.
