General Features General Features SIGLENT‟s SDS2000X series Super Phosphor Oscilloscopes are available in bandwidths of 70MHz, 100MHz, 200MHz and 300MHz, maximum sample rate of 2GSa/s, and maximum record length of 140Mpts. The most commonly used functions can be accessed with its user-friendly one-button design. The SDS2000X series employs a new generation of SPO technology. It has an innovative digital trigger system with high sensitivity and low jitter, and a maximum waveform capture rate of 140,000 wfm/s (normal mode), up to500,000 wfm/s (sequence mode). It also employs not only the common...

Prepare Information Before initiating performance verification or any adjustments, it is recommended to follow these procedures. The following topics are discussed in this chapter.  How to perform functional checks How to operate four standard interface tests How to recall factory Default settings Fore more detailed information about oscilloscope operation, please refer to theQuick Start. Functional checking The functional checking details three types of checks used to determine if the oscilloscope is operating properly. Power-on Inspection The normal operating voltage for SDS2000X series digital...

SIGLENT Note: to avoid electric shock, make sure that the instrument is correctly grounded to the earth before connecting AC power. Press the power-on button located at the lower left corner of the front panel and some keyswill be lighted for about 6 seconds simultaneously until the boot screen appears. Then the oscilloscope begins to perform its power-on tests automatically, after that you can press the DEFAULT SETUP button to recall the factory default settings.

Probe Compensation It is necessary to compensate the probe at first use so as to match to the probe ratio of current input channel. Non-compensated or poorly compensated probes may cause measurement inaccuracies or errors. The probe compensation steps are as follows: 1. Set the attenuation switch on the probe to 10X. Figure 2-2Set the attenuation switch 2. Connect the alligator clip of the probe to the Ground Terminal on the front panel firstly, and then use the probe to connect CH1 BNC connector and the Compensation Signal Output Terminal. Compensation Terminal Ground Terminal 3. Press AUTO...

Auto Setup Press Auto Setup keyto enable the waveform auto setting function. The oscilloscope will automatically adjust the horizontal time base, vertical scale and trigger mode according to the input signal to obtain anoptimum waveform display. Table2-2Auto setting menu Option （Multi-cycle sine） Introduction Display several waveform cycles （Single-cycle sine） Display single waveform cycles （Rising edge） Display the rising edge of waveform （Falling edge） Display the falling edge of waveform （Undo Setup） Recall the previous setup of oscilloscope The input signal frequency must be higher than 20Hz,...

Self Calibration The self-calibration routine can quickly make the oscilloscope to perform at the optimum state in order to achieve the maximum accuracy. You can perform self-calibration at any time, especially when the change of the environment temperature is up to or more than 5 ℃ or more. Make certain that the oscilloscope has been warmed up or operated for more than 30 minutes before the self-calibration. Use the following steps to perform self calibration: 1. Disconnect all the input channels. 2. Press theUtilitybutton on the front panel,and then press theDo Self Calsoftkey.The oscilloscope...

Interface Test The SDS2000Xseries oscilloscope is designed with four standard interfaces: USB Host, USB Device, LAN and Pass/Fail. Being connected to other instruments via these interfaces enables the oscilloscope to achieve even more enhanced capabilities. In order to ensure the oscilloscope is operating properly, it is recommended to first test the interfaces. USB Host Test To test if the USB Host interface is working normally. Tools: ●● A U disk Steps： 1. Insert a U disk into the USB Host interface on the front panel of the oscilloscope. 2. A prompt message, “USB Flash Drive Plug In!”,appears...
