In addition, frequency hopping is one of two basic modulation method used in spread spectrum signal transmission. This is really repeated switching of frequencies during radio transmission, often to reduce the effectiveness of electronic warfare. That is unauthorized interception or jamming of telecommunications. This also is known as frequency hopping code division multiple accesses.
A spread spectrum transmission offers there main advantages over a fixed frequency transmission. These are:
Basically spread spectrum signals are highly resistant to narrowband interference. The procedure of recollecting a spread signal spreads out the interfering signal, causing it to recede into the background.
At the same time, spread spectrum signals are really difficult to intercept. A frequency hopping spread spectrum signal appears as an increase in the background noise to a narrowband receiver. An eavesdropper would only be capable to intercept the broadcast if the pseudorandom series was known.
Spread spectrum is able to share a frequency band with many types of conventional transmissions with least interference. Actually the spread spectrum signals add minimal noise to the narrow frequency communications, and vice versa. As a result bandwidth can be utilized more professionally.
Actually the system incorporates a secure frequency hopping, spread spectrum radio link that greatly reduces outside electrical or RF interference. Active fail safe (shut down) with any loss of signal from transmitter. Rechargeable transmitter delivers 30 hours of continuous use between charges.
On the other side, the optional enable button requires two deliberate steps before signal is sent that is enable plug command signal. This is up to twelve preprogrammed high side or low side functions available.
Interference to OEM electronic controls can be simplified with factory installed, direct plug connectors. Optional prewired solenoids are available for pneumatic, hydraulic, or electromechanical machine control interference. Actually wireless remote controllers' modular components allow for easy installation and field.
These wireless industrial handheld transmitters are available with one through twelve buttons and corresponding receiver units are available with several output and range options. Outputs can be selectively interlocked to other operations for safety reasons and outputs can be sequenced with time delay or auto shut-off if required.
Optional receivers available to handle higher amperage loads, mix of high side and low side voltage, and dry contact relay outputs. Specify the 'H' receiver for these applications and the 'CP' receiver for fully potted electronics.
The transmitter has some specifications these are:
