Safety Notice

• The instrument casing can prevent users from touching the internal parts of the instrument, but the casing is not waterproof. Please cut off the power as soon as possible when liquid enters the interior.
• This product does not require forced ventilation. When the instrument needs to be installed in a enclosed space, please keep the air circulation in the enclosure to ensure the stability of the instrument’s performance.
• The RF output port on the front panel is only used for signal output. Adding electrical signals to this port should be avoided. The port can only withstand AC signal power not exceeding +25 dBm or DC voltage input of 16V(for a duration not exceeding 1 minute), otherwise the internal circuit may be damaged and malfunction will take place.

Overview

The LSG022 RF Signal Generator is a signal generator that can meet your needs within the 100 kHz to 20 GHz frequency range. You can use it to generate the signals required for manufacturing, R&D, repair service, and education. The supported signal
includes follows:

• CW signal
• Frequency Step sweep or amplitude sweep signal
• AM signal
• FM signal
• Phase modulated signal
• Pulse modulated signal

LSG022 supports the USB virtual-instrument technology, which is connected to the computer through USB and controlledbyLSG022 software. The product support the SCPI remote control and file operation. The LSG022 can be equipped with an industrial computer option to support desktop used, very similar to a traditional desktop instrument.

This manual is written according to LSG022 analog signal generator software version V1.0. Since we are constantly updating the product software to better meet your demands, please download the latest user manual on the Saluki website (www.salukitec.com) in time.

Start To Use

Software Installation

The LSG022 itself do not have a display interface, and the parameter settings and display function are provided by the software on PC .The application that controls this product needs to be installed on the PC before use. You can download or run the installer on the CD-ROM. This software installation package runs on Microsoft Windows systems, 32-bit and 64-bit versions are all available.

The installation files provided on the CD-ROM only support Windows XP sp1 and above operating systems. If you use other version of the operating system, please contact your Saluki dealer or FAE service for further information.

Run the installer by double click, specify the installation location and select Install. The installer will automatically complete the installation steps, as shown in Figure 1.
Fig. 1 Run the installer

The installation will launch the USB driver installation automatically. Please follow the installation prompts to install the USB driver, as shown in Fig. 2.
Fig. 2 Install the USB driver

After the installation of the USB driver is, the installer will launch of Microsoft .Net Framework installation, as shown in Fig. 3. If your computer already has a correct version of .Net Framework, Windows will prompt you do not need to install it. Follow the system prompts.
Fig. 3 Install .Net Framework

After the steps all above, the installer will prompt that the installation is complete. Click Finish to complete the installation.
Fig. 4 The installation is complete

Hardware Connection

Insert USB cable’s Type-C plug into (1) and insert the AC/DC power adapter’s DC plug into (2) in rear pane. Insert USB cable’s USB-A plug into one of your PC’s USB sockets. Insert the adapter’s AC plug into your 220VAC power system. If the power is OK, the indicator button (3) LED will turn blue.

The AC to DC adapter is 220VAC-12V/2A. The DC socket is a 5.5mm/2.5mm circular connector. The USB cable is a Type-C to USB-A cable with locking screws. The cable meets the transfer rate requirement for USB2.0 standard.
Fig. 5 Connect the Power Adapter and USB Cable

The power adapter in accessories is a two pin plug without ground pin. If you need the LSG022 to share the ground with the AC power supply system, you need to connect your ground wire to the metal part of the LSG022 metal case.

Confirm Connection Status

After LSG022 is powered and USB cable is connected to PC, enter the “Device Manager” of the windows control panel to check whether the LSG022 is recognized by the system. If it is correctly recognized, the Silicon Labs USB Device should be visible and in normal working state, as shown in the figure below.

Fig. 6 Check whether the LSG022 is correctly identified in “Device Manager”

Double-click the software icon to launch the LSG022 software. Every time when LSG022 is connected to PC, the software will automatically read the device calibration and configuration data , complete the initialization step and enter the working state. Before it entering the working state, all buttons on the GUI are disabled, and a prompt box of “read calibration data” is shown. This process may take several seconds. When you see the software buttons in available state, it means that the USB connection and hardware status are correct.
