The hardware tab now shows additional information about the connected device such as the firmware

version found on the device.

2.5.3 Firmware Update

The Spectrum Analyzer GUI provides a built-in updater that can update the SA430 firmware for new

features and bug fixes.

If the Spectrum Analyzer GUI determines that a firmware update is required, a message is displayed.

Click Update Firmware to start the update or click Decline to keep the existing firmware. Note that

declining a required update can prevent the SA430 GUI from using the SA430 hardware.

NOTE: Do not remove the SA430 from USB while updating firmware. This could lead to an

undefined state.

2.5.4 Ready for Operation

After the GUI establishes communication with the SA430 hardware, the connect icon is disabled and the

status bar shows a message to which COM port and device the GUI is connected (see Figure 3). The

software is now ready for the first measurement.

3 First Measurement

After the SA430 hardware is connected (Tip: Connection status is displayed on left side of the status bar;

see Figure 3) the Spectrum Analyzer is ready to operate. Set the desired Frequency and Amplitude, then

click the Start button (see Figure 4) to start measurement.

Figure 4. Start Button

Pressing the Start button not only starts a measurement, it also applies the RF settings for measurement.

To change RF settings during measurement, first enter the new settings and then apply them by pressing

the Start button again.

By default, the graph shows all settings and the measurement results (see Figure 5). Two traces are

automatically enabled. Trace 0 shows the actual (ACT) measured values, and trace 1 shows the

maximum (MAX) value for each measured frequency point since the start button was last pressed.

Results are displayed immediately in the graph window, which also shows all RF parameters.
