NEXNPK?
Syntax
NEXNPK?
Description
Within the waveform analysis range set with the “ANARANG” command on page 267,
searches for the minimum peak having a value more than the value of the negative peak
that has been detected at the last execution of this command or the “NPEAK?” command
on page 364, and reads out the measurement parameter value and sweep parameter value of
the negative peak. If there are several applicable negative peaks, reads out the value of the
leftmost negative peak within the analysis range. If no peak exists, 0 is read out.
The negative peak searched for at the execution of this command satisfies the condition set
with the “THRR” command on page 452. It is not related to the peak definition in the
marker search function. (Query only)
Query response
{numeric 1},{numeric 2}<newline><^END>
Readouts are as follows:
{numeric 1}: Measurement parameter value of the detected negative peak
{numeric 2}: Sweep parameter value of the detected negative peak
