5.2.6 Select Sweep Direction

There are two possible sweep directions on units with the Reverse

Sweep Option; Forward and Reverse. Use the edit box to select the

desired direction, and press the ENTER key.

Note: When sweeping, the direction may be changed by simply

pressing the left arrow key for reverse, or the right arrow key for

forward sweeping.

If the 3SRV is setup for multiple user operation with a 3HRV, reverse

sweeping is performed with the 3HRV, forward sweeping is performed

with the 3ST.

5.2.7 Adjust the Reverse Telemetry Level

This is the level of the carrier that the 3SR uses to transmit telemetry

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

appropriate value. When adjusting the Reverse Telemetry Level,

take into consideration the following losses; system, summing

network, test point, and amplifier desired input.

NOTE: The frequency of the reverse telemetry carrier is set on the

3ST/3HRV. There is no adjustment for the Reverse Telem-

etry Frequency on the 3SR.

5.2.8 Adjust the Reverse Sweep Insertion Level

This is the level at which the 3SR inserts (transmits) sweep points.

All sweep points are inserted at the same level. Use the edit box to

set the Reverse Sweep Insertion Level to an appropriate value (This

will typically be at maximum (+50 dBmV) to over come test point

loss.).

NOTE: The frequencies at which the sweep points are inserted are

defined in the Reverse Sweep Plan which is set on the 3ST/

3HRV. The frequency of the sweep points cannot be ad-

justed on the 3SR.
