IFB Frequency page
IFB FREQ: 2.403
Page purpose:
This page sets the IFB transmitter‟s center frequency.
Parameters:
(value range:
2.403
to
2.475
GHz, step:
.001
)
The IFB100 should be adjusted with a
minimum
2 MHz separation between channels. However, 8 MHz
separation between channels is necessary when using the Zaxcom Voting System (ZVS).
If the ZVS is enabled, you need to allocate four adjacent channels, 2 MHz apart, for the IFB100s. For example, the
ZVS would use 2.403 GHz, 2.405 GHz, 2.407 GHz and 2.409 GHz. This makes 2.411 GHz the next channel
available for another ZVS group.
Using 2 MHz spacing, the IFB100 can simultaneously support 36 IFB channels.
Selecting the frequency
If interference is encountered, the range of the system is affected. If the range is less than 150 ft., go to a different
channel at least 30 MHz away from the interfered channel.
There are many devices that use the 2.4 GHz band. The IFB100 should be able to operate interference free while
other devices share the band. It is suggested that when operating in a new location that a range test be conducted
before the unit is used for a production.
