Forward Telemetry Frequency

Use the UP and DOWN arrow keys or the numeric keypad to enter

the telemetry frequency.

NOTE: For successful Stealth mode operation, the Rx Foward

Telemetry frequency (3HRV) must match the Tx telemetry

frequency setting of the Model 3SRV.

Caution: Do not place the telemetry signal too close to the diplex

filter cut-off frequency in that roll-off may attenuate the

telemetry signal to the degree that communication fails.

This same caution applies to placing the signal in the high

end roll-off region.

Forward Telemetry Level

This is the level of the carrier that the 3HRV uses to transmit

telemetry data. Use the edit box to set the Telemetry Level to an

appropriate value. When adjusting the Telemetry Level, take into

consideration the following losses; system, summing network, test

point, and amplifier desired input.

Use the UP and DOWN arrow keys or the numeric keypad to enter

the telemetry level (20-50 dBmV).

Reverse Telemetry Frequency

This is the frequency at which 3SRV units with the Reverse Sweep

option will transmit telemetry data. Optimally this will be in a

portion of the reverse frequency band with at least 1 MHz free, and

at best case, in the high end of the return band to avoid potential

interference from ingress.

IMPORTANT: The frequency of the reverse telemetry carrier

should be carefully selected such that it will not

interfere with any existing carriers on the reverse

plant.
