Test Equipment
KVM connected
RF signal generator
Test Procedure
1. Connect the test signal generator to inject a signal at RF ahead of the LNA.
2. Enter the TTY setups through dspx.
3. Enter the Pr mode and make the following settings:
• Use the space bar to toggle to the power spectrum plot.
• Use the L/l and R/r commands to set the start to 50 μsec.
• Use the T/t command to set the plot span to 50 μsec.
• Use the V/v command to set averaging to 1 sample.
4. Set the signal generator power to a value that is approximately 60 dB above noise and
observe the scope plot.
5. Adjust the frequency of the test signal generator in 1 MHz increments to cover the
whole range of the scope plot. Mark the total power measured on the plot in the
following graph.
6. Verify that the 3 dB point gives approximately 14 MHz of bandwidth.
