VXI plug&play Programming Reference
hpe1437_trigger_phase_capture
Prepares for LO phase capture in frequency-synchronized, multiple-module zoom
measurements.
VXIplug&play Syntax
#include "hpe1437.h"
ViStatus hpe1437_trigger_phase_capture(ViSession id);
Description
Use this function if you intend to subsequently use
hpe1437_trigger_phase_actual_get to capture the LO phase on the next SYNC
assertion. You should send hpe1437_trigger_phase_capture to only one module in
the system (typically the master) after you have completed all frequency and filter setup
functions since those functions take the module out of the phase_capture mode.
Therefore, you should call this function just prior to starting the measurement.
When the hpe1437_frequency_sync mode is turned off, the
hpe1437_trigger_phase_capture function is not needed because the module will
revert to the phase_capture mode by default.
Parameters
id is the VXI instrument session pointer returned by the hpe1437_init function.
Effect on Active
This command does not abort any measurement in progress.
