Overview:DS213 is a "5-track 4-wave line" digital storage oscilloscope for general purpose engineering and electronic task based on ARM Cortex M3 core DS213 using FPGA to manage external control of ADC and data cache mode. It provides 4 application partitions to load and update up to 4 different application firmware. It also has an integrated 8 MB USB flash drive to store waveform data and update the system firmware. The oscilloscope code application layer is open source, and users can develop the oscilloscope firmware according to their needs.Features:Compact size, light weight, easy to carry and operate.Waveform data can be stored, and waveform analysis and comparison are more efficient and intuitive.Multiple trigger methods, support positive and negative edge trigger, logic trigger, pulse width trigger.With built-in 8M USB disk, large storage capacity.Specification:CPU: ARM Cortex M3FIFO & Control: FPGAADC: HWD9288-100Analog channels: 2 ( {CH_A} {CH_B} )Digital channels: 2 ( {CH_C} {CH_D} )Operation channel: INV {CH_A}, INV {CH_B}, {CH_A}+{CH_B}, {CH_A}-{CH_B}, {CH_C} & {CH_D}, {CH_C} |{CH_D}Vertical Sensitivity: 10 mV-10 V / div (1-2-2-5 Step) (using x1 of the probe)100 mV-100 V / div (1-2-2-5 Step) (using x10 of the probe)Vertical Resolution: 8 bitsStorage depth : 4 channels, 4*4 KInput coupling mode: DC, AC 400Vpp (using x10 of the probe)Soft trigger type: positive and negative edge trigger, pulse width trigger, logic triggerTrigger mode: automatic, standard, single, instant scanTrigger Source: {CH_A} {CH_B} {CH_C} {CH_D}Signal source: square wave 10Hz to 8 MHz, in total 20 changes and 3 sources of Vpp signal;Sinusoidal / triangular / sawtooth wave: 10Hz to 20 MHz, in total 11 changes and 3 Vpp signal sourcesStorage capacity: bulit-in 8M USB diskFile types: BMP,BUF, CSVAutomatic measurement type: maximum value, minimum value, crest value, average value, effective value, frequency, period, pulse width, duty cycleCursor measurement: time value, amplitude valueDisplay mode: (4 wave lines)Line 1: {CH_A}, HIDELine 2: {CH_B}, HIDELine 3: {CH_C} REC_1, REC _ 2, REC _ 3, REC _ 4 hideLine 4: {CH_D}, {CH_A} + {CH_B}, {CH_A} - {CH_B}, {CH_C} & {CH_D}, {CH_C} | {CH_D}, HIDESampling mode: Real-time samplingSampling frequency: 100MSa / sBattery: 1000mAhCertificate: CE FCCWeight: 296g/10.4ozSize: 99.5*58.5*13.5mm/3.9*2.3*0.5inchModelDS213MCUSTM32F103VEADCHWD9288Channel Number2 analog channel +2 digital channelAnalogBandwidth15MHzMaximumSampling Rate100MSa/sMaximum Storage Depth4KHorizontal Scanning Frequency100nS/Div~1S/Div(1-2-5 Step)VerticalSensitivity10mv/Div~10V/Div(1-2-5 Step)Input Impedance1MCouplingModeDC/ACTrigger Typeup / down triggerpositive / negative pulse trigger logic triggerAutomatic Adjustment ModeNoOperationWaveformINV A, INV B, A+B, A-B, C&D, C|D, RecA, RecB, RecC, RecDSignalOutputSquare wave, sine wave, triangle wave, saw tooth waveTrigger ModeAuto, Normal, Single, SlowMeasuredValueStorage Built-in 8M USB diskNumber of available APP quantity 2OperationKeys, EncodersUSB InterfaceMicro USBBattery1000mAhScreen Size3inchScreen Resolution400*240OpenSource SituationApplication layer open sourceCertificateCE/FCCPackage List:1 * Mini Oscilloscope1 * USB1 * Screwdriver
