ALARM FAILS VIEW
1) PLL Unlocked
This fail can happen in the case that PLL system doesn't reach enough voltage to get lock
the VCO
. The principal cause of this fail can be the initial moment when the Strider
Transmitter Link is turned on, in this case, observe that the second led that corresponds to
the “PLL Locked” doesn't light. This fail type can happen in less than 1% of the cases when
the equipment is altered the frequency out of the factory. Coming of it manufactures, the
equipment is adjusted among 1/2 VCC that means that the restraint bow is quite big and this
warning won't surely be exhibited in any case.

This view indicated are “readings”, and therefore cannot be modified.
2) VSWR PROTECTION
The Strider Transmitter Link is equipped with a modern and intelligent circuit to protect it for
any kind of antenna fail. If in the case that the antenna is disconnected, the transmitter auto-
protect itself automatically reducing the RF level to 0W.
Also, if the coax cable has not good impedance or fail in any connection, simplest the
equipment reduces the power and works in fold-back mode.
This circuitry is very fast, allowing that the transmitter has a long life.
Note that in the front panel exists a led to show if the RF power is operating, in this safety
mode, this led will be turned off.
This view, like the “PLL UNLOCK” are only “readings”and therefore cannot be modified.
