.SH DESCRIPTION

\fIe1432_set_center_freq\fR sets the center frequency for "zooming".
An error will result when attempting to set the center frequency
higher than what can be supported by the module.  See the discussion
of zooming under the \fIe1432_set_zoom\fR function for center
frequency limitations and the relationship between center frequency,
span and sample frequency.

\fIhw\fR must be the result of a successful call to
\fIe1432_assign_channel_numbers\fR, and specifies the group of
hardware to talk to.

\fIID\fR is either the ID of a group of channels that was obtained with a
call to \fIe1432_create_channel_group\fR, or the ID of a single channel.

\fIfreq\fR is the center frequency, in Hertz.

This function sets the center frequency of all input channels in the
module referred to by \fIID\fR.  By default, all source channels in
the module referred to by \fIID\fR will also get this same center
frequency.  The source channels can be given a center frequency
different than the input channels by using
\fIe1432_set_source_centerfreq\fR, which overrides
\fIe1432_set_center_freq\fR on source channels.

.SH "RESET VALUE"
Not applicable.
.SH "RETURN VALUE"
Return 0 if successful, a (negative) error number otherwise.
