Preparing for Operation

2.4.2 Cable

To improve power reading accuracy, a 50-Ω SMA cable can directly connect the Spectrum Analyzer with

the target system / transmitter.

To reduce influences from impedance mismatch, 50-Ω attenuators should be connected next to the SMA

connector of the Spectrum Analyzer. Depending on the target impedance, a 1-dB attenuator is sufficient.

CAUTION

Absolute maximum input level is +0 dBm. Exceeding this level can damage the

SA430.

2.5 Start Spectrum Analyzer Software

2.5.1 Launch

By default, setup.exe creates a shortcut to the software in the Windows® Start Menu and on the Desktop

from where it can easily be launched. It can also be started by running

%sa430_install_path%\SA430GUI.exe.

2.5.2 Connect with Hardware

The SA430 GUI starts in the Hardware tab to allow selection of the desired hardware (see Figure 1).

Figure 1. Hardware Tab

Assuming only one SA430 connected to this computer the connection can easily be made by pressing the

Connect symbol or the Connect button in the hardware tab (see Figure 2).
