Wavetek 3HRV Reverse Sweep Receiver

Used Wavetek 3HRV in good condition for sale. Unit shows some minor purely cosmetic defects--chips in paint around face edge and handles.

The 3HRV Reverse Sweep Receiver is a headend rack mounted unit that handles the reverse sweep job for up to 10 different technicians on the same cluster of nodes. The addition of the 3HRV to the Wavetek Sweep System takes the responsibility of the reverse sweep away from the 3ST. This serves to speed up the reverse sweep rate. In addition, the 3HRV sends out reverse ingress/noise information with every update of its forward telemetry, so reverse telemetry need not be received in order to check the reverse ingress condition.

Reverse Sweep Alignment

Reverse sweep alignment provides an optimum view of the frequency response in unoccupied reverse spectrum, leaving nothing to the imagination. A reverse sweep can uncover mismatch problems which reveal themselves as standing waves, or diplex filter roll-offs that can severely hamper the carriage of services in the reverse band.

Ingress Detection and Troubleshooting The 3HRV provides feedback to the field as to the current condition of noise and ingress in the headend. Even if the noise or ingress is "swamping" the telemetry a "picture" of the headend noise/ingress is sent out to the receiver via a special forward telemetry carrier for display.

Easy To Read Noise/Ingress Display

The headend instrument provides a continuous display of the noise/ ingress performance of the connected nodes. This provides a quick, easy way for the headend technician to verify performance. In addition, the current reverse testing activity can be monitored.

The 3HRV also performs essential cable TV system preventive maintenance tests with accuracy and ease. Signal levels, hum, C/N, and frequency response can be quickly tested without subscriber interference.

The 3HRV is a full-featured signal analysis meter, with a complete spectrum display and an analog representation of single channel measurement data. When tuned to a specific channel, a comprehensive set of information is provided: tuned channel, video frequency and level, audio frequency and level, the difference between video and audio carrier levels.

The 3HRV is a standard 19" rack mount unit, that weighs approximately fifteen pounds. Its 320 X 240 dot matrix LCD shows measurement data in both graphical and numerical form.
