4. Setup

4.1 Unpacking and Inspection

Upon receiving your signal generator, carefully unpack all components and inspect them for any signs of damage during transit. Retain the original packaging for future storage or shipping.

Figure 4.1: Product and Accessories. This image displays the signal generator along with its standard accessories, including power cables and BNC cables.

Verify that all items listed in the packing list are present. If any items are missing or damaged, contact your supplier immediately.

4.2 Connecting Power

1. Ensure the power switch on the rear panel is in the OFF position.
2. Connect the provided AC power cord to the AC power socket on the rear panel of the instrument.
3. Plug the other end of the power cord into a grounded AC power outlet. The device supports AC 85-264V, 47-63Hz.

4.3 Connecting Outputs

The device features two independent output channels, CH1 and CH2, located on the front panel.

• Use BNC cables to connect the CH1 and CH2 output ports to your desired load or measurement device.
• The output impedance is 50Ω (typical). Ensure your load impedance matches for optimal signal integrity.

4.4 Initial Power On

1. After connecting power, press the power switch on the rear panel to the ON position.
2. The display will light up, and the device will perform a self-test.
3. Once the self-test is complete, the main interface will be displayed, indicating the device is ready for operation.
