Sets the frequencies of clocks on the card.

Syntax
Visual Basic (Declaration) |

Public Sub SetClockFrequency ( _
clocks As Hil..::.Clock(), _
frequency As Double() _
) |
C# |

public void SetClockFrequency(
Hil..::.Clock[] clocks,

function setClockFrequency(clocks, frequency); |
Parameters
- clocks
- Type: array<
Quanser.Hardware..::.Hil..::.Clock
>[]()[]
An array containing the clocks whose frequencies will be set. Only hardware clocks,
such as Hil.Clock.Hardware0, should be specified.
Select a board type from the list for board-specific details:
.
- frequency
- Type: array<
System..::.Double
>[]()[]
An array of doubles containing the new
frequency for each clock in Hertz. Each element in
the frequency array corresponds to the same
element in the clocks array.
Hence, there must be as many elements in the frequency
array as there are clocks.
Remarks
Examples
This sample illustrates how to use the
SetClockFrequency(array<Hil..::.Clock>[]()[], array<Double>[]()[]) method.
It sets the frequencies of clocks 0 and 3 to 8.33 MHz and
sets channel 2 to 4.17 MHz.

board.SetClockFrequency(channels, frequencies);

Exceptions
Exception | Condition |
---|
Quanser.Hardware..::.HilException |
If the clock frequencies cannot be set then an exception is thrown. This situtation
typically arises when given frequencies are out of range or the card does not support
programming of the frequencies for its clocks independently.
