-In the following example we will show how to use the Network Analyzer to obtain the frequency response of a low pass filter circuit.+The following example we will show how to use the Network Analyzer to obtain the frequency response of a low pass filter circuit. When ever using the network analyzer, you need a stimulus/​reference channel (always waveform output channel 1 and oscilloscope channel 1) and a measurement channel (always oscilloscope channel 2).
  
 Consider the circuit in the figure below: Consider the circuit in the figure below:

-Oscilloscope Positive Channel 1 ('​+1'​) is used as reference channel, connected at the input of the filter along with the Waveform Generator channel 1 ('​W1'​) +To characterize ​the filter we need an input/stimulus, and way to measure ​the response,  
-Oscilloscope Positive Channel ​('+2'​) ​is connected at the ouput of the filter.+  - the reference channel: 
 +    * the stimulus : Waveform Generator channel 1 ('​W1'​)  
 +    * the reference channel measurement: ​Oscilloscope Positive Channel ​('+1') 
 +  - the response channel: 
 +    * the output ​of the filter ​: Oscilloscope Positive Channel 2 ('​+2'​)
  
-The oscilloscope negative input channels are connected to ground.+Since everything in this example is ground referenced, the oscilloscope negative input channels are connected to ground.
