Page 7: Source Code
Notably UI elements (e.g., buttons) also emit signals which are connected to the respective slot functions, though for these UI elements Qt auto-generates files at compilation which describe those particular connections.

Page 10: Setting Up Port Polling
‘POLL_TIMER’ is defined near the top of mainwindow.cpp as 1000. So, the timer operates at intervals of 1000ms, or 1 second. Every time it expires, the timeout() signal is emitted, which triggers the update_port_ list slot function.

Page 11: Updating The Port List
This approach lets the list stay up to date as needed, but avoids interrupting the user experience by constantly resetting the contents of the comboBox while the user is interacting with it.

Page 12: Ui Start-Up State
At start-up, the connection to the signal generator is not yet opened, so the connection buttons are enabled (and the disconnect button is disabled) using the show_connection_buttons function: AN-50-008 Rev: OR DCO-000822 (03/07/22) File: AN-50-008.docx This document and its contents are the property of Mini-Circuits.

If the port is opened successfully, the state of the GUI is updated. The connection buttons are disabled (disconnect is enabled), and all the other elements of the UI are enabled for the user to interact with.

Page 16: Auto-Detect & Connect
Then the ‘on_pushButton_connect_clicked’ function is reused to connect to the port. The selection of the ports occurs using the ‘autodetect_SG_port’ function: AN-50-008 Rev: OR DCO-000822 (03/07/22) File: AN-50-008.docx This document and its contents are the property of Mini-Circuits.

1. It takes the command string for the signal generator as an argument, checks whether the SG_port is still open at all before continuing, and then prepares a QString ‘rx’ in which to store a response to the command.

After breaking out of the while loop, the response string is printed in the communications log, and ‘rx’ is returned to the function which called writeRead, allowing further interaction with the response string if necessary.

Page 22: Executing A Sweep And Parsing The Data
If the sweep fails (for example because of an invalid input in the sweep lineEdits), it instead pops an error message and returns false, letting the program know it shouldn’t try to draw a plot from this data.

Page 24: Drawing A Plot From The Sweep Data
The visible limits of the plot’s Y-axis are set to smallest and largest S11 values multiplied by a factor of 1.1 for improved visibility. AN-50-008 Rev: OR DCO-000822 (03/07/22) File: AN-50-008.docx This document and its contents are the property of Mini-Circuits. Page 24 of 26... -
Page 25: Plot Notation Buttons
When either of these is pressed, they activate the ‘SWP_draw_plot’ function again, with either the linear or logarithmic notation. SWP_draw_plot re-uses the last known measurements stored in the QVectors to re- draw the plot.
