      Procedure to Capture ASK/FSK Signals Using the Oscilloscope

      This article describes how to set up the GRL-C3-TPT Tester and Tektronix High-Performance Real-Time Oscilloscope to capture the ASK/FSK signals in the manual mode.

      Minimum scope configurations: 

      Sample rate – 500MS/s

      Record length – 50M

      80ms capture

      Supported Tektronix scope models:

      DPO 7000 

      MSO 5204

      MSO54B 5-BW-350

      MSO54GSA:5-BW-350

      MSO44 4-BW-350

      MSO-X

      Procedure:

      1. Connect the TRIG1 and TRIG2 test points to the scope channel-1 and channel-2 respectively as shown in the images below.

      Note: User can connect to any scope channels. It is not mandatory to connect to channels 1 and 2 only.

      2. Make sure the scope is set up according to the minimum configurations as listed above.

      Example: 

      3. Execute any test case in the GRL-C3-TPT Browser App and capture the ASK and FSK signals.

      Note: Make sure the Trigger source and voltage are set according to the image in step 2 above before running tests.

      4. Analyze the FSK signal which is captured using the TRIG1 test point and ASK signal which is captured using the TRIG2 test point.
