Functions
uint64_t	ScpGetRecordLengthMax (TpDeviceHandle_t hDevice)
	Get the maximum supported record length of a specified device.
uint64_t	ScpGetRecordLength (TpDeviceHandle_t hDevice)
	Get the currently selected record length.
uint64_t	ScpSetRecordLength (TpDeviceHandle_t hDevice, uint64_t qwRecordLength)
	Set the record length.

Detailed Description

This section contains all record length related functions.

The record length defines the number of samples in a measurement. With a given sample frequency, the record length determines the duration of the measurement. Increasing the record length, will increase the total measuring time. The result is that more of the measured signal is visible.

The maximum supported record length depends on the used instrument and its configuration. Use ScpGetRecordLengthMax to determine the maximum supported record length of a device.

By default the record length is set to: 5000 samples.

Function Documentation

uint64_t ScpGetRecordLengthMax

(

TpDeviceHandle_t

hDevice

)

Get the maximum supported record length of a specified device.

Parameters

hDevice

A device handle.

Returns

The maximum supported record length.

uint64_t ScpGetRecordLength

(

TpDeviceHandle_t

hDevice

)

Get the currently selected record length.

Parameters

hDevice

A device handle.

Returns

The currently selected record length, in samples.

uint64_t ScpSetRecordLength	(	TpDeviceHandle_t	hDevice,
		uint64_t	qwRecordLength
	)

Set the record length.

Note

Changing the record length may affect the segment count value.

Parameters

hDevice	A device handle.
qwRecordLength	The required record length, in samples.

Returns

The actually set record length, in samples.
