Using the Network Analyzer
This guide walks through the process of setting up WaveForms' Network Analyzer instrument and plotting some data. The user interface of the instrument is briefly described.
1. Opening the Network Analyzer
1.1
Plug in your <test & measurement device>, then start WaveForms and make sure your device is selected.

1.2
Once the Welcome page loads, in the instrument panel at the left side of the window, click on the Network button to open the Network Analyzer instrument.

1.3
Once the Network instrument opens, the window contains the plot plane split horizontally into two subplot planes, the control bar above the plot planes, and the configuration panel to the right of the plot plane.

2. Using the Network Analyzer
This section walks through setting up the Network Analyzer to plot data from the Wavgen channels.
2.1 Hardware Setup
Connect the <test&measurement device>'s scope channel 1 pin (orange wire) to the device's wavegen channel 1 output pin (yellow wire). For devices that use differential input channels, such as the Analog Discovery Studio with MTE cables, make sure to connect the scope channel 1 negative pin (orange wire with white stripes) to the ground pin associated with wavegen channel 1 (black wire).

2.2 Run the Network Analyzer
By default, the Network Analyzer uses the <test&measurement device>'s wavegen channel 1 as the source signal and does not need any further configuration from the wavegen instrument window. From the control bar, click Run to continuously sweep the connected network port(s). While sweeping, Run button will now display Stop. Click Stop to end sweeping the network port. Click Single (to the left of Run) to sweep the network port only once. With the wavegen connected to the scope channel 1 input, the plot planes should show channel 1 (yellow traces) as a flat 0db magnitude plot, channel 2 (blue traces) magnitude plot increasing from -50dB to 40dB, and channel 2 phase plot decreasing from 90 degrees to 0 degrees.

2.3 Plot Plane Axes
BY default, the top plane is the magnitude response of the network port and the bottom plane is the phase response of the network port. Both plots share the bottom
