® LCD Display: Shows amplifier parameter settings and operating status. ® Buttons (from left to right): Mode switch, frequency switch, impedance switch, output switch. a. Mode Switch: STEADY (continuous mode), PULSED (pulse mode). b. Frequency Switch: FREQ RG 0.04~20kHz, 10kHz~150kHz. c. Impedance Switch: ROUT 4.3ohm/8.6ohm/17ohm/35ohm/69ohm/138ohm/277ohm/554ohm, 1.7ohm/3.4ohm/6.9ohm/13.8ohm/28ohm/55ohm/111ohm/222ohm. d. Output Switch: POWER OFF, OUTPUT OFF, OUTPUT ON. Function varies depending on the interface, as described below. Power Button: Turns on the power rail and enters Interface 2...

Output Button: Turns off the output and returns to Interface 2. In this interface, the mode switch and range switch buttons are disabled, and the frequency switch button functions as a save button; pressing it saves the current test parameters. ③ Adjustment Knob: Adjusts the output voltage percentage within the selected range. Clockwise rotation increases the gain, while counterclockwise rotation decreases the gain. Press the adjustment knob to toggle between coarse adjustment (1% step) and fine adjustment (0.1% step). ④ NC. ⑤ RS232: RS232 program control interface. ⑥ Input: BNC signal input...

4. Device Connections and Settings4.1 Signal Generator The input impedance of this product is 10kQ. To accurately obtain the voltage, the signal generator output • Use coaxial cables for input connections. • The input terminal of this product should be connected to the output terminal of the signal generator; The output terminal should be connected to the load under test; The monitoring port can be connected to an oscilloscope. • When operating at high frequencies, the inductance of the cables may reduce the output voltage, limiting the maximum power delivered to the load. For capacitive loads,...

5. Detailed Specifications Maximum Continuous Output Power 2600VA Note: ® During operation, the device must be used strictly within the specified bandwidth, maximum output voltage, and load limits. Over-range operation is strictly prohibited. ® The load impedance should be referenced according to the currently set output impedance (within the range of 90%R to -500%R without damage).
