## Function Documentation

## ◆ bladerf_get_rational_sample_rate()

API_EXPORT int CALL_CONV bladerf_get_rational_sample_rate | ( | struct bladerf * | dev,
|  | bladerf_channel | ch,
|  | struct bladerf_rational_rate * | rate )

Get the channel's sample rate in rational Hz

Parameters

  | dev | Device handle
  [in] | ch | Channel
  [out] | rate | Current rational sample rate

Returns
  0 on success, value from Error codes list upon failure

## ◆ bladerf_get_sample_rate()

API_EXPORT int CALL_CONV bladerf_get_sample_rate | ( | struct bladerf * | dev,
|  | bladerf_channel | ch,
|  | bladerf_sample_rate * | rate )

Get the channel's current sample rate in Hz

Parameters

  | dev | Device handle
  [in] | ch | Channel
  [out] | rate | Current sample rate

Returns
  0 on success, value from Error codes list upon failure

## ◆ bladerf_get_sample_rate_range()

API_EXPORT int CALL_CONV bladerf_get_sample_rate_range | ( | struct bladerf * | dev,
|  | bladerf_channel | ch,
|  | const struct bladerf_range ** | range )

Get the channel's supported range of sample rates

Parameters

  | dev | Device handle
  [in] | ch | Channel
  [out] | range | Sample rate range

Returns
  0 on success, value from Error codes list upon failure

## ◆ bladerf_set_rational_sample_rate()

API_EXPORT int CALL_CONV bladerf_set_rational_sample_rate | ( | struct bladerf * | dev,
|  | bladerf_channel | ch,
|  | struct bladerf_rational_rate * | rate,
|  | struct bladerf_rational_rate * | actual )

Configure the channel's sample rate as a rational fraction of Hz.

See also
  Use bladerf_get_sample_rate_range() to determine the range of supported sample rates.

Parameters

  | dev | Device handle
  [in] | ch | Channel to change
  [in] | rate | Rational sample rate
  [out] | actual | If non-NULL, this is written with the actual rational sample rate achieved.

Returns
  0 on success, value from Error codes list upon failure

## ◆ bladerf_set_sample_rate()

API_EXPORT int CALL_CONV bladerf_set_sample_rate | ( | struct bladerf * | dev,
|  | bladerf_channel | ch,
|  | bladerf_sample_rate | rate,
|  | bladerf_sample_rate * | actual )

Configure the channel's sample rate to the specified rate in Hz.

Note
  This requires the sample rate is an integer value of Hz. Use bladerf_set_rational_sample_rate() for more arbitrary values.

See also
  Use bladerf_get_sample_rate_range() to determine the range of supported sample rates.

Parameters

  | dev | Device handle
  [in] | ch | Channel
  [in] | rate | Sample rate
  [out] | actual | If non-NULL, this is written with the actual sample rate achieved.

Returns
  0 on success, value from Error codes list upon failure
