Learning to Make Transmission Measurements
This example procedure shows you how to measure the transmission response of a 175 MHz bandpass filter. The measurement parameters listed are unique to this particular test device.
For further measurement examples, refer to the “Making Measurements” chapter in the User's Guide.
Step 1. Choose the measurement parameters with your test device connected
1.Press the 
Preset
key to return the analyzer to a known state.
2.Connect your test device to the analyzer as shown in Figure
CAUTION Damage may result to the device under test if it is sensitive to the analyzer's default output power level. To avoid damaging a sensitive DUT, be sure to set the analyzer's output power to an appropriate level before connecting the DUT to the analyzer.

4.Look at the device response to determine if these are the parameters that you want for your device measurement. For example, if the trace is noisy you may want to increase the test port output power (which increases the analyzer input power), reduce the IF bandwidth, or add averaging. Or, to better see an area of interest, you may want to change the test frequencies.
