CaptureState

enum Hantek::CaptureState

The different capture states which the oscilloscope returns.

hantek/types.h

Enumerator
CAPTURE_WAITING	The scope is waiting for a trigger event.
CAPTURE_SAMPLING	The scope is sampling data after triggering.
CAPTURE_READY	Sampling data is available (DSO-2090/DSO-2150)
CAPTURE_READY2250	Sampling data is available (DSO-2250)
CAPTURE_READY5200	Sampling data is available (DSO-5200/DSO-5200A)
CAPTURE_ERROR

CommandIndex

enum Hantek::CommandIndex

Can be set by CONTROL_BEGINCOMMAND, maybe it allows multiple commands at the same time?

Enumerator
COMMANDINDEX_0	Used most of the time.
COMMANDINDEX_1
COMMANDINDEX_2
COMMANDINDEX_3	Used for ::BulkCode::SETTRIGGERANDSAMPLERATE sometimes.
COMMANDINDEX_4
COMMANDINDEX_5

ControlCode

enum Hantek::ControlCode : uint8_t

strong

All supported control commands.

All supported control commands. 0xE0 CONTROL_SETVOLTDIV_CH1 CH1 voltage div setting (6022BE/BL)

0xE1 CONTROL_SETVOLTDIV_CH2 CH2 voltage div setting (6022BE/BL)

CONTROL_SETTIMEDIV Time divisor setting (6022BE/BL)

CONTROL_ACQUIIRE_HARD_DATA Request sample data (6022BE/BL)

Oscilloscope Command	bRequest Value	Other Notes
Set CH0 voltage range	0xE0	Possible values: 1,2,5,10 (5V, 2.5V, 1V, 500mV).
Set CH1 voltage range	0xE1	Possible values: 1,2,5,10 (5V, 2.5V, 1V, 500mV).
Set Sampling Rate	0xE2	Possible values: 48, 30, 24, 16, 8, 4, 1 (MHz) and 50,20,10 (*10kHz).
Trigger Oscilloscope	0xE3	Possible values: 0: start sampling, 1: stop sampling
Set channel count	0xE4	Possible values are 1 (CH1 only) and 2 (CH1 and CH2)
Set Calibration Freq	0xE6	Possible values: 1, 2, 5, 10, 20, 50, 100 (kHz)
		Possible values: 105 (50 Hz), 110 (100 Hz), 120 (200 Hz), 150 (500 Hz)
Read/Write Firmware	0xA0	Read or write the scope firmware. Must be done on scope initialization

The 0xEx requests are sent with value 0x00. The calibration commands are sent with value 0x08 (offset into eeprom). The value for R/W command is dependent on the Cypress protocol for interacting with the firmware.

A bulk read from end point 0x86 reads the current contents of the FIFO, which the ADC is filling.

ControlValue

enum Hantek::ControlValue : uint8_t

strong

All supported values for control commands. VALUE_OFFSETLIMITS [MODEL_DSO2090, MODEL_DSO2150, MODEL_DSO2250, MODEL_DSO5200, MODEL_DSO5200A]

Value 0x08 is the calibration data for the channels offsets. It holds the offset value for the top and bottom of the scope screen for every gain step on every channel. The data is stored as a three-dimensional array:
channelLevels[channel][GainId][LevelOffset]

VALUE_DEVICEADDRESS [MODEL_DSO2090, MODEL_DSO2150, MODEL_DSO2250, MODEL_DSO5200, MODEL_DSO5200A]

Value 0x0a is the address of the device. It has a length of one byte.

VALUE_FASTRATECALIBRATION [MODEL_DSO2250, MODEL_DSO5200, MODEL_DSO5200A]

Value 0x60 is the calibration data for the fast rate mode on the DSO-2250, DSO-5200 and DSO-5200A. It's used to correct the level differences between the two merged channels to avoid deterministic noise.

VALUE_ETSCORRECTION [MODEL_DSO5200, MODEL_DSO5200A]

Value 0x70 contains correction values for the ETS functionality of the DSO-5200 and DSO-5200A.
