Chapter 1 Overview RIGOL Chapter 1 Overview Test Preparations The following preparations should be done before the test: 1. Self-test 2. Warm-up (make sure that the instrument has been running for at least 30 minutes) 3. Self-calibration Self-test When the oscilloscope is in power-on state, press the power key at the lower left corner of the front panel to start the oscilloscope. During the start-up, the instrument performs a series of self-test items.
RIGOL Chapter 1 Overview Specifications The specification of each test item is provided in chapter 2. For other specifications, refer to DS1000Z-E Data Sheet (available to download from RIGOL official website (www.rigol.com)). Tip: All the specifications are only valid when the oscilloscope has been warmed up for more than 30 minutes.
RIGOL Chapter 2 Performance Verification Test Chapter 2 Performance Verification Test This chapter introduces the performance verification test methods and procedures of DS1000Z-E series digital oscilloscope by taking DS1202Z-E as an example. Fluke 9500B is used in this manual for the tests. You can also use other devices that fulfill the “Specification” in Table 2-1.

Connect the active head of Fluke 9500B to CH1 of the oscilloscope, as shown in the figure above. 2. Configure the oscilloscope: 1) Press CH1 in the vertical control area (VERTICAL) on the front panel to turn on CH1.

Connect the active head of Fluke 9500B to CH1 of the oscilloscope, as shown in the figure above. 2. Turn on Fluke 9500B and set its impedance to 1 MΩ. 3.
RIGOL 2) 3) 4) Chapter 2 Performance Verification Test 200 mV/div, 500 mV/div, 1 V/div, 2 V/div, 5 V/div and 10 V/div respectively. Adjust the output voltage of Fluke 9500B to 3 × the current vertical scale and -3 × the current vertical scale respectively. Repeat steps 3 to 7 and record the test results. Calculate the relative error of each vertical scale: |(Vavg1 - Vavg2) - (Vout1 - Vout2)|/ Full Scale × 100%. 10. Turn off CH1.
RIGOL Chapter 2 Performance Verification Test Bandwidth Test The bandwidth test verifies the bandwidth performance of the oscilloscope by testing the amplitude loss of the oscilloscope under test at full bandwidth. Specification Bandwidth Amplitude Loss[1] 200 MHz -3 dB, all-channel mode Note[1]: Amplitude Loss (dB) = 20 × lg (Vrms2/Vrms1); wherein, Vrms1 is the measurement result of amplitude effective value at 1MHz and Vrms2 is the measurement result of amplitude effective value at full bandwidth.
RIGOL 9. Chapter 2 Performance Verification Test Calculate the amplitude loss: Amplitude Loss (dB) = 20 × lg (Vrms2/Vrms1). 10. Keep the other settings of the oscilloscope in Step 3 unchanged and set the vertical scale to 500 mV/div. 11. Output a Sine with 1 MHz frequency and 3 Vpp amplitude via Fluke 9500B. 12. Repeat Step 5. 13. Output a Sine with 200 MHz frequency and 3 Vpp amplitude via Fluke 9500B. 14. Repeat Step 7-9. 15. Turn off CH1. Test CH2 using the method above and record the test results.
RIGOL Chapter 2 Performance Verification Test Bandwidth Limit Test The bandwidth limit test verifies the 20 MHz bandwidth limit function of the oscilloscope by testing the amplitude loss of the oscilloscope under test at the bandwidth limit. Table 2-2 Bandwidth Limit Input Impedance of the Oscilloscope 1 MΩ Available Bandwidth Limit 20 MHz Specification Bandwidth Limit Amplitude Loss[1] -3 dB, all-channel mode Note[1]: Amplitude Loss (dB) = 20 × lg (Vrms2/Vrms1).
