Chapter 3 Remote Control RIGOL Remote Control Via USB 1. Connect the device Connect the RF signal generator (USB DEVICE) and PC (USB HOST) using a USB cable. 2. Install the USB drive This RF signal generator is a USBTMC device and the Found New Hardware Wizard dialog box will be displayed after the RF signal generator is correctly connected to the PC (the RF signal generator will be automatically configured to the USB interface) and both of them are started.
RIGOL Chapter 3 Remote Control Remote Control Via LAN 1. Connect the device Connect the RF signal generator to your LAN. 2. Configure the LAN parameters Set the LAN parameters of the RF signal generator according to the description in "I/O Configuration LAN". 3. Search for the device resource Start-up Ultra Sigma and click ; then, click in the pop-up window and the software starts seaching for the RF signal generator resource connected to the LAN.
Chapter 3 Remote Control RIGOL resource name of the instrument and selecting "LXI-Web". Various important information about the instrument (include the model number, manufacturer, serial number, description, MAC address and IP address) will be displayed on the webpage.
Chapter 4 Application Examples RIGOL Chapter 4 Application Examples This chapter introduces the basic operations of the instrument using specific examples so that users can quickly master the using methods of the RF signal generator.
RIGOL Chapter 4 Application Examples To Output a RF Signal Output a RF signal with 1 GHz frequency and -20 dBm amplitude from the [RF OUTPUT 50Ω] connector. 1. Restore to the factory setting Press Syst Reset Preset Type "Factory" and then press Preset to restore the instrument to the factory setting. 2. Frequency setup Press FREQ, use the numeric keyboard to input the frequency value (1) and select the desired unit (GHz) from the pop-up unit menu.
Chapter 4 Application Examples RIGOL To Output a RF Sweep Signal This section introduces how to output a RF sweep signal by configuring continuous linear step sweep. Set the frequency range to (1 GHz to 2 GHz), the amplitude range to (-20 dBm to 0 dBm), the number of sweep points to 10 and the dwell time to 500 ms. 1.
RIGOL 3. Chapter 4 Application Examples Turn on the RF sweep Press SWEEP Sweep and select "Freq & Lev" to turn on the frequency and amplitude sweep functions at the same time. At this point, the RF signal generator sweeps from the start frequency and level to the stop frequency and level continuously at certain step according to the current settings.
Chapter 4 Application Examples RIGOL To Output a RF Modulated Signal This section introduces how to output an AM modulated signal by taking amplitude modulation (AM) as an example. Set the carrier frequency to 800 MHz, the carrier amplitude to -20 dBm, the AM modulation depth to 60% and the modulation frequency to 20 kHz. 1.
Chapter 5 Troubleshooting RIGOL Chapter 5 Troubleshooting The chapter lists the commonly encountered failures of DSG800 and their solutions. When you encounter those problems, please solve them following the corresponding steps. If the problem remains still, please contact RIGOL and provide your device information (Syst Information System Info). 1. The screen of the RF signal generator is still dark (no display) after the power key is pressed.
RIGOL Chapter 5 Troubleshooting 4. The setting is correct but the waveform output is incorrect. (1) There is no RF output — Check whether the signal connecting cable is tightly connected to the corresponding [RF OUTPUT 50Ω] connector. — Check whether the connecting cable has internal damage. — Check whether the connecting cable is tightly connected to the test instrument. — Check whether the backlight of RF/on is illuminated. If not, press this key to illuminate the backlight.
Chapter 5 Troubleshooting RIGOL — Make sure that at least two points are set in the step sweep or list sweep. (2) The dwell time of list sweep is incorrect — Press SWEEP List Swp to enter the sweep list menu. — Press Load to load the desired sweep list and press View to check whether the dwell time in the sweep list is correct. — If the dwell time is incorrect, re-edit the sweep list and load it to the instrument. If the dwell time is correct, turn to the next step.
RIGOL Chapter 5 Troubleshooting (3) Check whether the RF signal generator is working under the specified environment temperature. (4) Check whether the test is being performed in a highly magnetic environment. (5) Check whether the power supplies of the RF signal generator and test system have strong interference. (6) Check whether the performance of the test device meets the requirement. (7) Check whether the test device is within the calibration period.
