Software

  • LabVIEW

This article will show you how to configure the gain and frequency of SC2215 RF amplifier. Additionally, as the module contains power detectors, this article will show you how to monitor the output power during the runtime.

There are no default LabVIEW examples shipped with SC2215 instrument drivers. However, this RF Amplifier can be configured and monitored in LabVIEW as given below:
  • Install the module, and the required drivers and configure the device in NI MAX as given in the getting started guide for SC2215.
  • Once SC2215 instrument driver support is added for the current LabVIEW version on your computer, open a blank LabVIEW VI, navigate to its Block diagram, right-click>>Instrument IO>>Instr Drivers>>SI 2215 palette.
  • For a basic operation, use 'Initialize.vi' to open a reference to the device. The 'Resource Name' control can be provided by a string.
  • In the 'Configuration' sub-palette, use 'Configure Frequency.vi' and 'Configure Gain.vi' to configure the frequency and gain for each channel. Please note that SC2215 uses '0' and '1' as its channel names that can be passed using a string control or constant.
  • Similarly, a signal path can be configured using 'Configure Path.vi'. You can find more information regarding the available signal paths in the block diagram of the device.
  • To monitor the power output or temperature of the device, use the respective VIs available in the 'Measurement' sub-palette. These VIs can be used within a loop for continuous monitoring.
  • To end the session, use 'Close.vi' in the main palette.
Note that several above configuration and monitoring operations are supported using a property node as well. Also, the SC2215 instrument driver comes with calibration APIs available in the same palette.

Refer to the below code snippet for a better understanding of the above steps.
