Qualifier X-Ray
Qualifier X-Ray System Overview
The ComSonics Qualifier X-Ray System provides a method for identifying the
internal shielding integrity of the CATV network in a subscriber’s residence without
the need to enter the premises.
A test activation transmitter is located within the Qualifier hand held device (HHD).
The transmitter provides an activation signal to the Qualifier Vehicle Mounted
Device (VMD) and sets up the HHD to measure levels of ingress from the VMD
signal appearing in the return upstream path.
With the HHD connected to either the residential ground block or the drop tap, a
press of the HHD button activates the VMD to generate a brief 5-watt signal pulse
at a frequency, just above the CB radio band, within the upstream frequency spectrum.
The VMD test signal envelopes the residence with a level of about +58 dBmV
(assuming the service vehicle is about 75 feet from the residence). Shielding
flaws, within the residential cabling, allow the VMD signal to enter the return upstream path. The HHD detects the VMD test signal and displays a shielding integrity value based on the ingress level measured.
The threshold setup function in the HHD determines the indication of PASS or
FAIL with the integrity measurement.
Shielding Integrity Measurement
The Qualifier X-Ray System utilizes a unique measurement method to determine
the relative shielding integrity of a customer premise without a need to enter the
structure. This method provides the user with a numeric display representing a
calculated shielding factor, in dB, of the premise under test.
The type of flexible coaxial cable used for drops and house wiring typically has a
shielding integrity factor in the range of 60 to 80 dB. But with the addition of connectors, splitters, VCRs, televisions, PC modems, and other devices along with
improper installation techniques; the total overall shielding integrity can degrade
appreciably. The possibility of noise ingress (undesirable signals) increases
greatly if the shielding integrity is not sufficient. Noise ingress causes interference
with the return path signals and reduces the reliability of two-way signal communications.
The Qualifier X-Ray System enables the user to obtain a shielding integrity reading in the range of 80 dB (very good) to 25 dB (very poor). Each measurement
reading includes a PASS or FAIL indication, based on a user selectable threshold
value, for easy measurement status determination. The threshold function can be
turned off.
Formula for calculating the shielding integrity reading:
D2I = Pmax [+85] - (antenna gain [2.5] + free space loss [25]) - measured value
*D2I is the acronym for Dwelling Ingress Integrity

General Information
Hand Held Device
The Hand Held Device (HHD) is a small pocket size unit containing the test activation transmitter and the ingress test signal
receiver.
Battery Installation
The HHD is powered by three standard AAA alkaline batteries.
To install the batteries, loosen the battery compartment screw
and remove the cover. Install the batteries, all three with the
positive end in the same direction, as indicated. Replace the
cover and tighten the screw. Use care not to over tighten the
screw.
Be sure to recycle or properly dispose of old batteries.
The HHD automatically powers off when the battery condition
is low to protect the batteries from excessive discharge and
possible leakage. Periodically remove the battery cover and
inspect the batteries for signs of leakage.
Caution: Do not store the HHD for extended periods of time
with the batteries installed. Failures due to battery leakage are
not covered under warranty.
Single Button Control
The HHD is controlled by one multi-function button.
To power the HHD on:
Press and hold the Button for one second.
To activate an integrity measurement cycle:
Press the Button once.
This also resets the back light and power auto-off timers.
To access the PASS/FALL threshold setup mode:
Press the Button twice within one second.
Press the Button to set the threshold level.
To power the HHD off:
Press and hold the Button for one second.
Auto Power Off
The HHD automatically powers off sixteen seconds after the last Button press.
The back light turns off in six seconds and the HHD powers off ten seconds later.

Qualifier X-Ray
Display Screen
The Display screen provides information on the
battery condition, units of measure, shielding
integrity value, and if enabled, the PASS/FAIL
status of the measurement. A back light illuminates the display.
Battery Level
A fresh set of batteries is indicated by four bars.
Each bar represents approximately 25% runtime
capacity. A low battery condition is indicated by
no bars showing. The HHD automatically powers off when the battery state is low.
Note: The accuracy of the battery level indicator is relative and will vary with the
battery type and manufacturer.
Shielding Integrity Measurement Value
When a measurement is made, by a single press of the Button, the level of the
ingress signal is displayed as a shielding integrity value in dB units-of-measure.
The value range is 80 dB (very good shielding) to 25 dB (very poor shielding).
PASS / FAIL Function
The HHD can be setup with a measurement threshold value to determine if the
integrity reading is acceptable. PASS is displayed if the measured integrity value
is higher (better) than the threshold value. FAIL is displayed if the measured integrity value is lower (worse) than the threshold value. The PASS/FAIL threshold
value is user selectable. This function can be disabled as described on the next
page.
Threshold Value Setup
To access the threshold value setup mode, press the Button twice within one
second when the HHD is on. The PASSFAIL readout activates and two digits
display the current threshold value. Press and hold the Button to scroll to the desired threshold value. Release the Button to stop rapid scrolling and then use
single presses of the Button to the desired value. If a lesser value is desired, continue to hold the Button as the value wraps around from 80 and then back down to
25 dB. Release the Button and allow the HHD to auto power off (six seconds). At
the next power up, the newly set threshold value is enabled and the PASS or the
FAIL indicator will display accordingly. See the next sections for the procedure to
disable or enable the PASS / FAIL function.

1 - 8 0 0 - 3 3 6 - 9 6 8 1
Disable the PASS / FAIL Function
The HHD PASS / FAIL function can be disabled by setting the threshold value to
80 dB. In this mode, neither the PASS nor the FAIL indicator appears.
Enable the PASS / FAIL Function
To enable the HHD PASS / FAIL function, set the threshold value to a setting
other than 80 dB.
Test Signal Verification
The combined PASSFAIL label is displayed along with the integrity reading if the
HHD is unable to clearly receive the VMD test signal. The HHD performs a pretest
signal level measurement prior to triggering the VMD and then compares that
level with the measurement made during the VMD transmit interval. If the VMD
signal level is no greater than the pretest level, then the combined PASSFAIL
label is shown. The test signal verification function is not affected by disabling the
Threshold function.

Qualifier X-Ray
Install the VMD Power Harness
Connect the RED lead to the vehicle (+12V) ignition or accessory fuse block circuit. Connect the BLACK lead to the vehicle ground. A 2-ampere safety fuse is
used in the red lead.
Connect the power harness to the VMD.
The red Standby indicator is on with power applied and the VMD Power Switch
set to OFF.
Check / Select the VMD Transmit Frequency
Push the VMD power switch to the ON position; wait a few seconds for the VMD
to initialize, and the green Power indicator to illuminate. Then, press and hold the
Test button for 2 seconds. The orange Receive indicator flashes showing the
operating frequency by the following patterns:
One flash and a pause frequency 1 = 27.45 MHz
Two flashes and a pause frequency 2 = 27.47 MHz (factory default)
Three flashes and a pause frequency 3 = 27.49 MHz
To select a different transmit frequency while a code is flashing; press the Test
button to step to the next frequency. The frequency select sequence wraps
around from frequency 3 back to frequency 1.
The VMD returns to normal operating mode after the indicator flashes the code
sequence for 10 seconds. The selected operating frequency is retained regardless
of powering conditions.
In accordance with FCC License requirements, the operating frequency may need
to be changed. Refer to the Qualifier Transmitter Licensing section on our website at ‘www.comsonics.com/downloads.html’ for application instructions and templates.
Test the VMD Installation
Push the VMD power switch to the ON position and wait a few seconds for the
VMD to initialize. Momentarily press the Test button and the yellow Transmit indicator comes on for a few seconds as the VMD generates the output power signal
to the antenna.
Warning: The Dual Band Antenna must be properly mounted on the vehicle and
connected to the VMD before performing this test or operating the Qualifier system. Improper operation of the system may result in permanent damage to the
VMD and is not covered under warranty.

1 - 8 0 0 - 3 3 6 - 9 6 8 1
Qualifier System Installation Verification
1. Power-on the VMD and wait a few seconds for it to initialize.
2. On the HHD, connect a ≈ 2 inch stub antenna to the BNC connector.
(Example: Use a straightened paperclip inserted into a BNC-to-F adapter.)
Make sure the HHD batteries are fresh.
3. Stand about 10 feet from the vehicle and hold the
HHD with a vertical orientation of the stub antenna.
4. Power on the HHD and then press the Button.
5. The VMD orange Receive indicator flashes once
and then the yellow Transmit indicator comes on for
a moment.
6. The HHD displays ‘ - - dB’ briefly and then shows a
reading between 25 and 80 dB.
Note: If the HHD shows ‘> 80 dB’ and the
‘PASSFAIL’ label, check the Dual Band Antenna
connection and repeat the ‘Test the VMD Installation’ procedure.
7. Set the HHD Threshold to a value less than the
displayed reading.
8. Repeat the test and note that PASS is displayed.
9. Set the HHD Threshold to a value greater than the
displayed reading.
10. Repeat the test and note that FAIL is displayed.
11. Set the HHD Threshold Level to 80 dB.
12. Repeat the test and note that neither PASS nor FAIL is displayed.
13. Reset the HHD Threshold to a value for system test operation.
Troubleshooting Notes:
If the trigger signal from the HHD is marginal, the VMD orange Receive indicator
flashes several times and the yellow Transmit indicator does not come on.
If the VMD is triggered by the HHD and the orange Receive indicator flashes once
(as normal) but the yellow Transmit indicator does not come on, there is a problem with the antenna or the internal transmitter section of the VMD.
If the TEST button on the VMD is pressed momentarily and the yellow Transmit
indicator does not come on, there is a problem with the antenna or the internal
transmitter section of the VMD.
The reliability of the HHD triggering the VMD may be reduced in these test location scenarios:
The elevation of the HHD test location is significantly lower than the VMD
vehicle antenna.
The residence under test, located between the HHD and the VMD vehicle,
significantly blocks or absorbs the HHD trigger signal.
1. Locate the Qualifier VMD equipped vehicle about 50 to 75 feet from the test
residence.
2. Set the VMD power switch to ON.
3. Disconnect the CATV drop cable from the residence ground block or splitter.
As an alternative method, disconnect and test at the tap or pedestal.
4. Use a BNC-to-F adapter and a short jumper cable to connect the Qualifier
HHD to the open residential terminal. If using the tap or pedestal method, connect the HHD to the free end of the drop cable. If needed, use a quality extension cable and a F-81 barrel. Tighten connections as needed.
5. Power on the HHD.
6. Press the HHD Button to activate the measurement
sequence.
7. The HHD displays ‘- - dB’ briefly and then shows the
shielding integrity reading. PASS or FAIL may also be
displayed, based on the Threshold value setting.
8. Repeat the measurement sequence a second time to
insure the reading.
For a low integrity reading from a tap or pedestal
location, retest from the residence ground block or
splitter location.
For a low integrity reading when connected to the
input of the residential splitter, disconnect each cable from the splitter output (one at a time) and retest
to determine the path of ingress.
If the PASSFAIL label appears, the indication of not
clearly receiving the VMD test signal, check the HHD
connection and the VMD operation. Integrity readings in the range of 25 to 80 with the PASSFAIL
label showing may indicate excessive noise signals.
9. Disconnect the HHD jumper cable and reconnect the drop cable.
10.Weather-proof the connection as needed.
