Diamond Engineering DAMS 000 Series User manual

DAMS - Desktop Antenna Measurement System
x000, x100, and x250 Series
Users Manual & Setup Guide

Congratulations on your purchase!
Diamond Engineering’s Desktop Antenna Measurement System has been designed to aid in the
testing and development of small to medium sized antennas. Using our state of the art software, this
system enables you to make many different types of measurements with complete user-denable
conguration settings. The “Advanced Processing” features enable you to not only plot 3D graphs
of the measurements, but also to save and recall those measurements for future use or comparison.
Using the “Group Delay” function, you can calculate the exact distance to the test Antenna, identify
multi-path rays, and eliminate the need for other measuring devices. Our software also allows you
to export your data to a 3rd party application or spreadsheet.
This manual will fully assist you with the assembling and conguring as well as teach you how
to utilize the many features of your Desktop Antenna Measurement System. To achieve the full
functionality of the rotator system, it’s expected the user has some working knowledge about the
concepts and theories involved in microwaves and antenna design development.
We cannot emphasize the importance of fully reading and understanding this manual enough
before actually using the equipment, as to avoid damaging the unit and/or possibly voiding your
warranty.
Best regards,
The Diamond Engineering Team

Introduction
BEFORE YOU BEGIN: Unpack ALL items and ensure there are no damaged or missing parts.
NOTE: The x000 Series is designed for non-FSM measurements using elevation motor.
Vertical Assembly
1. Unfold tripod and extend the top half-way, then secure the height adjustment. (Fig. 1)
2. Take the grey vertical spacer and snap it onto the very top of the tripod neck. (Fig. 2)
IMPORTANT: Without this piece, your unit will not make accurate vertical measurements.
3. Attach the vertical assembly onto the top of the tripod using the included hex wrench so the top
edge of the vertical assembly is touching the bottom edge of the vertical spacer. (Fig. 3)

x000 Installation & Conguration
Attaching Optional Thrust Plate
1. Ensure the azimuth setting on the
tripod is unlocked.
2. Place the tripod head in a horizontal
position and tighten the locking screw.
3. Align the colored tape on the platform
with the tape on the tripod head and
insert the platform into the head at a 30°
angle. The head will automatically lock
the platform into position.
4. Loosen the tilt lock screw (see Img. 2)
allowing the platform to tilt. Connect the
vertical actuator rod to the platform and
tighten the locknut while holding the hex
shaft using a wrench, ensuring the rod does
not disconnect.
Instructions
Applies to acrylic and aluminum models only.
The thrust plate attaches using the four 10-32x1/4”
screws. Do not overtighten screws. If using your own
screws, be careful not to hit the metal bearing below.

Hardware Setup
1. Setup the tripod and extend the neck upwards about 14”.
2. Carefully thread the DAMS positioner onto the tripod.
3. Remove 2 of the 4 thrust plate screws to make room for the FSM mount.
4. Attach the FSM to the top of the DAMS positioner using the included screws as shown in
the attached pictures. The mount is adjustable to allow you to “phase center” the antenna
on the Elevation/Vertical Axis.
5. Connect the cables as shown in the photos above.
NOTE: The support struts shown in the photo are not required. We’ve since updated
with a thicker bottom plate to minimize/eliminate exing.
Software Setup
Click “Congure Positioner” and ensure USB/Serial is selected. Place a check-mark in the FSM
box. Press save, then “restart with default extents” When you restart the software, you will see
the updated positioner picture.
Assembly & Installation (with FSM-5)
IMPORTANT: For FSM-10 installation, please refer to the separate FSM-10 installation manual.

Cable Checklist
You should have received the following ve cables with your DAMS System:
Two (2) 10-foot RF Cables SMA/2.92mm/2.4mm/ or V 1.85mm cables (or optional 20-
foot cables)
One (1) USB cable (USB to Micro-USB)
Two (2) 6-meter platform control cables
Cable Connections
NOTE: For FSM-5 connections, see photo on Page 11.
Step 1 Connect USB cable to Platform Controller but DO NOT connect to PC.
Step 2 Connect the power supply wire to the Platform Controller.
Step 3 Connect one end of calibrated SMA cable to bottom of platform.
Step 4 Attach other end of SMA cable to VNA.
CAUTION: USE CARE! Damaged cables will compromise results!
Step 5 Connect straight end of the yellow cable with the black band on the
connector to the “Horizontal” port on Platform Controller and
non-banded cable to “vertical” port.
Step 6 Connect other ends of yellow cables to platform. The banded rightangle
connector connects to turntable, and the non-banded connector
connects to vertical actuator.

Controller Setup & USB Driver Installation
Connecting Controller and Installing USB Drivers -(USB / USB-RS232)
1. Connect DAMS Platform Controller to computer via USB Cable. A window should
appear indicating a new device has been found.
IMPORTANT: When possible, always allow Windows to check for updated driver.
2. If Windows cannot nd the driver, Check the box labelled “Search Manually” then
click “Next”.
3. Select c:\DAMS\driver (if windows does not accept this driver go to
http://www.ftdichip.com and download the latest VCP drivers.)
4. A new window should pop up indicating another device has been found. Allow
Windows to search for an updated driver if you did before. If not, repeat these
steps.
Conguring DAMS Software for x000 Series Positioners
1. Start the DAMS software
2. Click the “Positioner Settings” button
3. Select the USB/Serial option in the upper right from the “Select Controller” pull
down. Click the “Find” button, which should nd your controller (NOTE: the
controller must be on a COM port lower than COM8. If it is not, please congure
the USB/Serial adapter via Control Panel → Device Manager → Ports → COM & LPT.)
4. Set “Motor Res” to .1125 and gear ratio to 14.4 on both AZ and EL elds.
5. The USB controller conguration is now complete. If no controller is found, follow
the troubleshooting instructions below. (NOTE: the COM port must me 9 or lower
for the software to communicate with the controller, this can be changed in
device manager)
6. Press “SAVE” button, followed by “QUIT’ to save changes. Restart software.
Troubleshooting
1. Check all connections between Controller and PC
2. Click Start → Control Panel → System → Hardware Tab → Device Manager
3. Expand section labeled Ports Com&LPT. DAMS Platform controller should be
listed with an associated COM Port. If no controller is listed, re-install the driver.
Please contact us if you need any assistance.

Calibrating Vertical Movement to Zero Degrees
IMPORTANT: For the software to move the platform correctly on the vertical
axis you must have the platform at zero degrees when starting
the DAMS Software, or the platform must match the vertical
position shown in the software before moving vertically.
IF THE PLATFORM ANGLE AND SOFTWARE ANGLE DO NOT MATCH:
Use the Jog +/- pull-downs to move the platform to the level position. Once you have
reached the desired position, press “ZERO POSITIONER” to set the current physical
position as “0,0”.
NOTE: If you exit the software without returning to zero, you must follow the
above instructions to once again re-set the positioner to zero degrees.
Verifying Positioner Connectivity and Operation
These steps will assist you with verifying the x000 Series positioner’s operation with the
DAMS software. All steps for installing and conguring the software and connecting
cables should be completed before performing the following steps.
1. Ensure power supply is plugged in and start the DAMS Software.
2. Elevation / Vertical Movement Test
Select -45 from “El jog to” (See image below) pull-down - positioner should tilt
45 degrees towards reference antenna. Select +45 from “El jog to” pull-down and
positioner should tilt all the way to +45 degrees.
3. Azimuth / Horizontal Movement Test
Select 180 from “Az jog to” pull-down. Positioner should rotate 180 degrees of
reference antenna. Select 360 from “Az jog to” pull-down and positioner should
nish the rotation to 360 degrees. (See image below)
4. Resetting to 0, 0 Degrees
After completing the tests, click to clear all position settings and
move the positioner to 0 degrees azimuth and 0 degrees elevation.
