Rhino 2 Precision Frequency Source
The Rhino 2™ includes an internal
8-channel GPS (Global Positioning System) receiver that synchronizes
the 1 PPS, 1/2 PPS and Adj PPS signals to GPS time. The battery allows
the Rhino 2 to be internally powered, for short
periods of time, in an area with GPS coverage to synchronize and then
moved without loss of synchronization. All functions are controllable
via RS-232 from a PC.
For
Laboratory Use:
The Rhino 2 provides precision reference
frequencies including many used by popular CDMA test equipment. An internal
battery protects against loss of lock during AC power interruptions,
or the unit may be unplugged and moved to another location without losing
synchronization.
For
Field Use:
The Rhino 2 is a precision frequency
source for field use. It is also ideal in situations with limited or
no GPS coverage. It directly connects to modified BVS equipment (currently
the Super Eagle and Eagle), The internal battery conditions vehicle
power and acts as an Uninterruptable Power Supply (UPS) for the Rhino 2 and the Super
Eagle.

The
Rhino Controller application software is the Windows 95/98 interface
that enables a user of the Rhino Frequency Source. The Rhino Controller
provides a programmable chip offset, which allows synchronization of
an output adjustable pulse-per-second (PPS) to 1PPS with a desired offset
from 1 to 32767 CDMA chips. The Rhino Controller application mimics
the display panel for the Rhino. The status is constantly updated approximately
every other second as well as the GPS receiver status. The information
is updated on the PC display as it comes in through the RS-232 port.
The chip offset may be set from 0-32767 in this application.
In
addition to the status being updated in the display, the GPS Lock, Clocks
Locked and Rubidium Lock simulated LED's will light up for the appropriate
conditions. There are two status bars located on the bottom of the screen.
The "RHINO STATUS" bar displays the current chip offset, the
last offset drift, the firmware version, and the real-time clock. |

How
do I read GPS information?
Simply
click on the 'GPS DATA' button. All information reported by the internal
GPS receiver will be displayed.
How
do I set the chip offset?
Click
on the 'SET OFFSET' button. Then enter a valid offset number. Choosing
'OK' will report back the new offset within a few seconds. |
