the forward telemetry frequency from the 3HRV and the forward
telemetry frequency from the 3ST, your receiver does not have the
proper version of firmware (8.3 or above) to function with the 3HRV.
The 3SRV must also be set to the 'multiple user' mode even if only
one of the allowed ten persons is sweeping. If you do not have the
proper firmware version, call Wavetek Technical Support for
upgrade instructions. The level of the forward telemetry signal is
again very critical. Proper telemetry level can be achieved by
inserting the signal from the 3HRV into your system using the same
method and level settings as for the 3ST. In figure below, DC-A and
DC-C have the same value, as also the forward telemetry levels from
the 3ST and the 3HRV. As with the 3ST, the reverse telemetry level
at the input of 3HRV should be 0 dBmV ±10 dB. You must also
rebuild your reverse channel plan in 3HRV and, if you wish, you can
disable the reverse sweep feature of the 3ST. This will speed up the
forward sweep somewhat.
The above guidelines are quite general and your system may require
a slightly different hook-up. However, the levels mentioned are
extremely critical and should be met to ensure proper functioning of
your Stealth Sweep System.
