9 Performing measurement tasks - program-
ming examples
If you install the optional software development kit (SDK) of the R&S NRP Toolkit, pro-
gramming examples are provided. See Chapter 5.1, "R&S NRP Toolkit", on page 20.
Under Windows, these examples are installed under:
C:\ProgramData\Rohde-Schwarz\NRP-Toolkit-SDK\examples
This chapter gives programming examples for measurement tasks performed with the
NRP power sensors.
9.1 Performing the simplest measurement
The simplest way to obtain a result is to use the following sequence of commands:
*RST
INITiate
FETCh?
The *RST sets the continuous average mode.
INITiate initiates the measurement.
After *RST, the trigger system is set to TRIGger:SOURce IMMediate. That means
the power sensor starts measuring when the measurement is started without waiting
for a trigger condition.
After the measurement has been completed, FETCh<Sensor>[:SCALar][:
POWer][:AVG]? delivers the result to the output queue from which it can be fetched.
9.2 Performing a buffered continuous average measure-
ment
This example, written in pseudo code, shows how to set up and execute a buffered
continuous average measurement.
//Select whether using
// 'BUS Trigger' --> true
// or 'EXT Trigger' --> false
bool bUseBUSTrigger = true;
// Use the first NRP series sensor which is found
if ( VI_SUCCESS == SENSOR.openFirstNrpSensor( "USB?::0X0AAD::?*::INSTR" ) )
{
//Start with a clean state
SENSOR.write( "*RST" );
