I Product Intro DS203 is a 5-trace 4-channel digital oscilloscope for common electronic engineering tasks. Its CPU is based on ARM Cortex M3, adopting FPGA to manage the control & data buffering of ADC. A built-in 2MB USB disk enables users to store waveforms & upgrade firmware. It also provides 4 application areas, convenient for users to load &...
2. Simultaneously press || of DS203 and turn on power supply, enter DFU firmware upgrade mode. 3. Use USB to connect DS203 to your PC, A removable disk named “DFU V3_10_D” will appear on your PC. Copy the firmware to the root directory of this disk then restart DS203, thus firmware is upgraded.

menu. Calibrat Instrument calibration (make Press (―…+) to confirm, press sure CH_A is ground connected) (■) to calibrate. IX Application Examples: 1. Example One:Measure simple signals Observe one unknown signal in a circuit, measure & display the frequency & peak-to-peak value of the signal. Please operate according to following steps: Connect the probe of CH_A/CH_B to the detection point of the circuit.
This function can catch occasional incidents very easily; e.g. a sudden sentus of high amplitude. Set the trig level a little higher than normal signal level, press (||), and when the sentus occurs, the device will automatically trig & store the waveforms before & after the trig. It’s depicted as the figure below to better observe the changes of waveforms before &...
Cycle 4. Example Four: Comparison of Waveforms Module E(REC_A/ REC_B/ REC_C/ REC_D) can be used to compare standard signal & unknown signal. Please operate according to following steps: Input standard signal to CH_A, press (■), choose Save Dat 01 to save waveform, as in Figure 4.1: Input unknown signal to CH_ A, in E position choose REC_A, press (■), choose Load Dat, as Figure 4.2: Move P position Y to adjust horizontal level, to compare waveforms, as in Figure 4.3: Figure 4.1...
Figure 4.2 Figure 4.3 5. Example Five: Save waveform images Sometimes waveform images need to be archived/analyzed on PC platform. Please operate according to following steps: With prerequisite of correct measurement of signal source, press (■), choose Save Bmp 01, scroll (―…+) to choose file no., press (―…+) to confirm.
X Operation Tips 1. When measure high frequency signals, to enhance scan speed, it’s suggested to lower buffer depth by adjusting S position, 360 points as a window, and adjust X in Q position to observe the buffer waveforms in the memory.
