3. Main Menu

Pressing the MENU soft-key on the main Run screen takes you to a menu of all of the XR-3 screens. Some of these screens are also available via shortcut soft-keys from the Run Screen.

You can navigate the Main Menu using the up/down and Enter keys. Some functions are also available via soft-keys as a shortcut. “Exit” takes you back to the Run Screen.

The functions are described in the sections that follow.

4. Channel Plans

From the Run screen, press ‘Menu’ soft-key, then select ‘Channel Plans’ from the Main Menu to reach the Channel Plans screen. Select a channel plan corresponding to the type of channels in the system you are testing. This step is essential since the XR-3 only tunes to relevant channel numbers and their frequencies and signal types based on this information.

Page 8 of 55

XR-3 Cable Air Module Operation Manual XR-3

This screen is a simple menu selection. To select and activate a plan, use the up/down arrow buttons to highlight the selection you want to use and press ENTER. To create a new custom channel plan, highlight a standard plan to be used as the base plan and press the Edit/Create soft-key. See more details below in the Custom Plans section about how to create custom channel plans. To edit a custom channel plan, select an existing custom channel plan and press the Edit/Create soft-key.

Due to the large variety of systems in use, the Channel Plans selection is divided into three sections:

1) Standard Cable Plans

2) Standard Off-Air Plans

Standard Cable Plans

When the unit is shipped from the factory, it will have the most common compatible cable channel plans for North America loaded:

 EIASTD – This plan is designed for and automatically detects North American EIA analog

(NTSC) & digital (QAM64 or QAM256) signals from 55.25 MHz to 997.25 MHz (analog) or 57.00 MHz to 999.00 MHz (digital).

 HRC

 IRC

 SECAM

Page 9 of 55

XR-3 Cable Air Module Operation Manual XR-3

Standard Off-Air Plans

When the unit is shipped from the factory, it will have the most common compatible off-air channel plans for North America loaded:

 NTSC ATSC – This plan is designed for and automatically detects North American analog (NTSC) & digital (8VSB) signals from 55.25 MHz to 747.25 MHz (analog) or 57.00

MHz to 749.00 MHz (digital).

 FM N. Am – This plan tunes to the 100 analog FM carrier frequencies from 88.100 MHz to 107.900 MHz.

Custom Plans

Create a Custom Channel Plan

There are 3 ways that you can create a custom channel plan:

1) Use the Channel Scan feature and then from the Save menu, select “Save Found

Channels as new Plan”.

This method is desirable if you’re at a site and want to find which channels are present on the existing cable or off-air system. After selecting the appropriate base Standard Cable or Standard Off-Air channel plan, connect the meter to a coax cable and run a Channel

Scan. The meter will automatically find the active channels and determine if they are analog or digital and will save the channel plan with the signal type detected.

2) Manually edit all of the desired channel numbers and frequencies using the meter. In the

Channel Plans section of the Main Menu, highlight a Standard Cable or Standard Off-Air plan to be used as the base plan and press the Edit/Create soft-key. This allows you to save the standard channel plan lineup under a different file name (Save As) so that the new custom plan can be edited. This method is desirable if you just want to slightly modify the channel lineup from the way it is in the Standard Plan.

Or highlight a custom channel plan in the Custom Plans section and press the

Edit/Create soft-key to edit the channel lineup and individual channel parameters. You can change the filename, if desired (Save As), to create a new custom channel plan from an existing custom plan.

3) Use the MeterMaid application on a PC to load a custom channel plan (.pln) file after editing the plan file using a text editor (i.e. Notepad or Notepad++)

Create Custom Channel Plan by Scanning Channels Present On Active System

1) Connect the XR-3 to an off-air antenna (that is already aligned) or to your cable system and detect your channels to create a custom channel plan

Menu soft-key to enter the Main Menu b. Select ‘Channel Plans’ and press Enter. c. Highlight the desired channel plan to use as your base plan and then press

Enter. d. If you haven’t already, connect a coax cable from the cable system or off-air antenna’s output to input port of XR-3’s Cable Air module. e. While on the main Run screen where your bar graphs are, press the ‘Chan Scan’ soft-key to initiate a channel scan. The meter will sound an audible tone (beep) when the scan is complete. f. If you wish to pick favorite channels and tilt channels, highlight the desired channel using the up/down arrow buttons and then press the Fav/Tilt soft-key

(by pressing the #1 button on the alphanumeric keypad that corresponds to that soft-key). Press soft-key once to flag the channel as one of your favorites. Press

Page 10 of 55

XR-3 Cable Air Module Operation Manual XR-3 soft-key a 2 nd

time to flag channel as one of your tilt channels. Press soft-key a

3 rd

time to remove the flags. You may pick up to 5 favorite channels per channel plan. The 2 tilt channels count as favorite channels as well.

Choosing favorite channels in an off-air plan can be very useful since you’ll then be able to view all 5 favorite channels on the screen at once (in the Favs Graph) while aligning the off-air antenna. Since off-air antenna alignment sometimes ends up being a compromise because some transmitter towers are located in one direction and other transmitter towers are located in another direction, seeing multiple channels on the screen at once is critical to be sure that improving the signal on one channel isn’t significantly degrading the signal on another channel. the that corresponds to that soft-key). h. Then select ‘Save Found Channels as new Plan’. If you have flagged any channels as favorite / tilt channels, then these will be saved to the new plan, too.

Edit a Base Channel Plan and Save As New Custom Channel Plan

b. Select ‘Channel Plans’ and press Enter. c. Highlight the desired channel plan to use as your base plan and then press the

Edit / Create soft-key. d. In the Channel Plan File Summary screen, i. Using the alphanumeric keypad, type the desired filename for your custom channel plan in the Filename field and then press Enter. ii. Specify the location, technician name, and enter any notes in their respective fields, as desired. iii. In the ‘LNA voltage’ field, select whether you want to allow voltage output from the meter for this channel plan or not (choices are 13V, 18V,

NONE). You would want to allow voltage output if you envision powering off-air antenna pre-amplifiers using the XR-3 while your custom plan is selected. You would not want to allow voltage output if the channel plan is designed for CATV testing. iv. Press Next soft-key to enter the Channel Lineup screen. v. Delete any channels that you don’t wish to measure (if the off-air channels don’t exist in your area or the cable channels aren’t active on your system) by highlighting the channel and then pressing the Delete soft-key. vi. To edit the parameters of any channel, highlight the channel and press

Enter to enter the Channel Parameters screen.

1. You may edit or enter a new Channel Number by entering the new desired channel number (i.e. 2, 4.1, 6, 44.1, 52, 61.1, etc.) using the meter’s alphanumeric keypad. Then press Enter.

2. You may edit or enter a new Channel Label by entering the new desired channel label (i.e. ESPN or CNN or KTFD-DT or WTTV, etc.) using the meter’s alphanumeric keypad. Then press Enter.

3. If the channel is a digital channel, then you should ensure that these parameters are entered in the following fields: a. For UHF digital off-air (ATSC A/53) channels: i. Type:

9. Spectrum Screen

The spectrum screen may be used to:

 Look for the presence of carriers

 Look at a carrier with an incompatible modulation type or encryption

 Look for interfering signals

This feature imitates a spectrum analyzer although it has less resolution and a slower sweep rate than an actual spectrum analyzer. This screen has the following features:

 Adjustable frequency span

 Automated level scaling cursors

 Adjustable sweep rate

Page 34 of 55

XR-3 Cable Air Module Operation Manual XR-3

To view the spectrum display:

Press the Spect. shortcut soft-key on Run screen or

Press the MENU soft-key in bottom right hand corner of main Run screen. Then use your up/down arrow keys to highlight ‘Spectrum’ and press ENTER.

The spectrum screen will automatically start sweeping and by default, the frequency of Marker 1 will be on the center frequency of the channel you had selected on the Run screen (for digital channels) or will be on the video carrier frequency of the channel you had selected on the Run screen (for analog channels) with the minimum frequency span.

Soft-Keys:

1) MRK1 / MRK2 / CTR FREQ – MRK1 or MRK2 allows you to select which marker is active

(either Marker 1 or Marker 2). ‘CTR FREQ’ allows you to quickly jump through the frequencies with the paging function while maintaining the same span.

2) LVL – performs Automated Level Scaling

3) Menu – displays the Spectrum Menu

Cursor Position

Press Left/Right arrow buttons to move active cursor (either MRK1 or MRK2) horizontally to different frequencies on x-axis. To jump to a particular frequency, use numeric keypad to type in desired frequency and then press ENTER. The frequency of each cursor (marker) position is shown in the bottom row in the lower area of the screen and is color coded to match the color of the related marker.

You will notice that the signal level for each cursor (marker) will automatically adjust as the frequency of the cursor changes, riding on the power curve. The numeric signal level measured at each cursor’s (marker’s) position is also shown in the bottom area of the screen and is color coded to match the color of the related marker. Note: Signal Level displayed will depend on whether you have selected dBm, dBmV, or dBµV in the Options menu.

Span

Press the Up arrow button to zoom in (less span). This will cut the displayed span in half around the active cursor's frequency position. Minimum span is 9 MHz.

Page 35 of 55

XR-3 Cable Air Module Operation Manual XR-3

Press the Down arrow button to zoom out (more span). This will double the displayed span around the active cursor's frequency position. Full (maximum) span is 995 MHz (i.e. 5 to 1000

MHz).

Start and Stop frequencies may also be set manually in the Settings section of the Spectrum

Menu.

Paging

Press the upper right soft-key twice until ‘CTR FREQ’ is displayed. Then press the Left / Right arrow buttons to "page" to the left or right, changing the start and stop frequencies, but maintaining the same span (when not at full span). This allows you to quickly jump through the full range of frequencies.

Amplitude Range

The default amplitude range shown on the spectrum display is -30 to +40 dBmV. Press the LVL soft-key on middle right side of the screen to perform auto level scaling. Each time you press the

LVL soft-key, the instrument will rescale the amplitude range according to the min/max amplitude levels detected during the last sweep. The auto level scaling makes the measured signal levels more obvious and easier to see.

Ceiling and floor levels may also be set manually in the Settings section of the Spectrum Menu.

Spectrum screen before pressing LVL to perform auto level scaling:

XR-3

Resolution and Refresh Rate

Press +/- key on numeric keypad to change the number of samples per sweep. You can choose between 60, 120, 240, or 480 samples. 60 samples results in lower resolution and less detail, but a faster sweep. 480 samples results in a higher resolution and more detail, but a slower sweep.

By default, the meter measures 240 samples to create a picture of the power spectrum.

The samples may also be modified in the Settings section of the Spectrum Menu.

Spectrum Menu

From within the Spectrum Screen, press Menu soft-key to enter the Spectrum Menu.

Spectrum Menu fields include:

 Save Spectrum – allows you to save a screenshot of the screen as it appeared immediately before entering the Spectrum Menu for later recalling and viewing in the meter or on a PC

XR-3 Cable Air Module Operation Manual XR-3

 Open Spectrum – allows you to open and view a previously saved spectrum

 Add Reference – allows you to add a reference to the spectrum screen, which could be a spectrum at the same site performed at an earlier time on the same carriers, or the same signal at another point in the network to show the change.

 View Present Spectrum – allows you to return to the Spectrum screen

 Settings – allows you to manually modify the spectrum screen settings

Settings

For the top five fields, use the up/down arrow buttons to highlight a field and then use the left/right arrow buttons to change the setting in the field.

For the bottom four fields, use the up/down arrow buttons to move cursor to a field, use the numeric keypad to type a setting into the field, and then press ENTER.

 Samples – allows you to modify the number of samples per sweep, as described above in the Resolution and Refresh Rate section

 Attenuator Level – allows you to set desired attenuator level setting, from 0 to 55 dB (in increments of 5 dB) or set to AUTO. Default setting is AUTO.

 Peak Hold Line – allows you to turn ON or OFF the peak hold line. In addition to the present power measurement line (shown in royal blue color), turning this function ON will display a line (shown in turquoise color) at the maximum amplitude at each frequency that has been detected in previous sweeps du

 

ring this session. By default, the Peak

Hold Line is turned OFF.

Page 38 of 55

XR-3 Cable Air Module Operation Manual XR-3

 Vertical Bar Marker - allows you to turn ON or OFF the vertical bars for MRK1 (marker 1) and MRK2 (marker 2). The vertical bars make it much easier to see the frequency of where each of your markers is positioned. By default, the Vertical Bar Marker is turned

ON.

 Horizontal Bar Marker - allows you to turn ON or OFF the horizontal bars for MRK1

(marker 1) and MRK2 (marker 2). The horizontal bars make it much easier to see the RF level of where each of your markers is positioned. By default, the Horizontal Bar Marker is turned ON.

Page 42 of 55

XR-3 Cable Air Module Operation Manual XR-3

Soft-Keys:

1) Stop – stops the plotting of the constellation diagram

2) Save – allows you to save the present constellation scan

3) Clear – clears the present constellation diagram (new diagram will begin to be plotted)

4) Zoom Select – allows you to select a quadrant to zoom in on

5) Zoom In – zooms in on selected quadrant to get closer look at constellation

6) Zoom Out – zooms out to go back to full constellation plot view

7) Exit – exits to Run screen

BER

The Bit Error Rate (BER) of the signal, as detected by the demodulator chipset in the XR-3’s

Cable Air module, is displayed in the top right corner of the constellation screen.

The meter displays the errors Pre-Viterbi (before the Viterbi decoder) and Post Viterbi (after the

Viterbi decoder).

Page 43 of 55

XR-3 Cable Air Module Operation Manual XR-3

If the error rate is preceded by a less than sign (<), it indicates that no errors have yet been detected and so the bit error is not known but is less than the number given.

The BER displayed accumulates errors as long as the screen is active. To reset the counters, exit and restart the constellation screen.

This test can only be performed when a signal lock is obtained. If the lock is lost, the rates are not shown and will be restarted when lock is re-obtained.

In most cases, a one minute test is sufficient to determine the BER for the present conditions. As long as both rates continue to read less than some number (the < character is shown), then no errors have been detected and the system is working well.

11. Voltage / Current

The V/I or Voltage / Current Screen displays:

LNA – voltage output supplied to LNA or antenna pre-amp mAmps - current draw of LNA / pre-amp

Ohms – Impedance or resistance of system, as calculated by voltage output and current draw

Battery - meter’s internal battery voltage (Full is approximately 12.6 volts and empty is approximately 10.9 volts).

Ext DC – amount of voltage being supplied to instrument by external AC to DC switching power supply connected to DC charge port on bottom panel of instrument

Soft Keys

1) 13V

2) 18V

- Turns on the output voltage at 13 volts DC

- Turns on the output voltage at 18 volts DC

3) OFF

4) EXIT

- Turns LNA output voltage power off

- returns to the Main Menu screen

The XR-3 (with the Cable Air module loaded) can output 13 or 18VDC to power LNA’s or antenna pre-amplifiers (pre-amps).

Utility

The File Utility feature allows you to see the filenames that you have used for saved scans and custom channel plans. You can also delete a single file or format the flash drive and therefore erase all saved files from the flash memory of the selected drive.

Press MENU soft-key and then select ‘File Utility’ from Main Menu list.

By default, the File Utility function displays the filenames of all saved files. To filter the saved files, first press the File Set soft-key and then use up/down arrow keys to select “CATV / OTA

Files”, then press Enter. Then press the File Type soft-key and use up/down arrow keys to select desired file type (i.e. Channel Scans, Favorites, Spectrum Scans, Constellation Scans, Limits files, or Channel Plans), then press Enter.

Page 45 of 55

XR-3 Cable Air Module Operation Manual XR-3

To delete a single file, highlight the file using the up/down arrow keys and then press the Del File soft-key. Note that erasing a single file does not free up flash memory. You must use the Format function to really erase the files. To format the flash memory and erase all saved files on the drive, press Format soft-key.

Each CATV / OTA file type is designated by a different file type extension:

Cable & Off-Air Channel Scan (FAIL) = .CCSF

Cable & Off-Air Channel Scan (PASS) = .CCSP

Cable & Off-Air Channel Scan (NO LIMITS) = .CCSN

Cable & Off-Air Favorites = .CFAV

Cable & Off-Air Spectrum Scans = .CSPC

Cable & Off-Air Constellation Scans = .CCON

Cable & Off-Air Limits = .CLIM

Cable & Off-Air Channel Plans = .PLN

XR-3 Cable Air Module Operation Manual

13. Options

There are several options you may select to personalize the operation of your meter.

XR-3

To use this screen, highlight the option you want to change with the up/down arrow buttons and select the value you want with the left/right arrow buttons. Press Menu when done.

Level

The signal level may be displayed in dBm, dBmV or dBµV.

Sounder

Antenna peaking via the audible tone can be done in two ways: “tone-on-lock” and “peak-omatic”. The “tone-on-lock” method uses the following:

1) Slow beep - the function is on

2) Fast beep – the digital signal is locked

3) Solid – the digital signal is locked and at the highest level yet seen

This method works well when the antenna is close enough to obtain a signal lock. If you have trouble finding a lock however, you may want to use the “peak-o-matic” method:

1) Slow beep – the function is on

2) Fast beep – the signal is at least 5 dB higher than the lowest level seen

3) Solid – the signal is higher and at the highest level seen so far

Note that the peak-o-matic method does not indicate a lock. It allows you to peak the azimuth even before a peak is obtained.

In both methods, to fully peak the antenna, you must move it in one direction until the signal is found, and continue moving it until you move past the peak, then move back to the solid tone.

Shutdown Timer

The unit can be set to automatically shut off after 5, 10, or 15 minutes with no buttons being pressed. This timeout can be disabled by setting the option to “none”.

Page 47 of 55

XR-3 Cable Air Module Operation Manual XR-3

Key Beep

By default, key beep is on and you will hear an audible “beep” when any buttons on the meter are pressed. You can turn off the key beep if desired.

Sort Order

By default, the channel lineup on the Run screen is sorted by Frequency. If desired, you can sort channel lineup on the Run screen by Channel number.

Display Theme

By default, display theme is ‘Light’, with a white screen background. You can select the ‘Dark’ display theme to enable a black screen background, if desired.

Preset

Pressing the Preset soft-key in the Options menu will return the XR-3’s cable air module settings to its factory default settings (will return the RF signal level field to its default dBmV value, will return the Sort Order preference to sort by frequency, etc.).

Date / Time

Pressing the DATE TIME soft-key in the Options menu will take you to a new screen that allows you to specify and store the date and time for the meter’s internal clock. The date and time are displayed on scan results.

14. Versions

Versions

Selecting Versions from the Main Menu list takes you to a screen that displays versions of software that are loaded in the instrument. It also displays the hardware versions and serial numbers of the XR-3 base unit and any connected module, as well as the active channel plan and Limits file.

Page 48 of 55

XR-3 Cable Air Module Operation Manual XR-3

Page 49 of 55

XR-3 Cable Air Module Operation Manual XR-3

15. Power

LNA Power

The LNA current is limited:

1) Normal battery operation:

Current Limit

780 mAmps

2) Charger active (AC): 780 mAmps

Under conditions 1 and 2, an inrush current of 900 mAmps is allowed for a short period of time.

Battery Charge

1) Charging: Use either the AC to DC switching power supply or the 12VDC vehicle charger.

To fully charge a dead battery, it should require approximately 3 hours. It is okay to leave the meter charging all night since the smart battery charge circuitry will throttle back charge rate as required to prevent over-charging of the battery. During cold weather keep the XR-3 indoors in a warm environment while charging. The battery charge temperature range is 41°F to 100°F or 5°C to 38°C. Only use replacement batteries from

Applied Instruments.

2) Discharge / Charge: Before initial use of the meter you should fully discharge the battery and then recharge overnight. To discharge the battery, disable the automatic shut-off in the Options menu and then leave XR-3 powered on until it shuts off.

3) Battery Charge Symbol: The battery symbol indicating remaining battery life in the lower right corner of the LCD display can be misleading. It is normal for the battery symbol of a fully charged battery to quickly drop by ¼. The symbol should remain in the middle two segments for the longest time period, and will again drop faster when the last battery symbol segment is displayed. In summary, the symbol drops by 25% quickly, remains in the middle 50% the longest, and then the last 25% drops quickly.

The symbol’s (and the battery’s discharge) behavior is non-linear. The battery charge indicator is based on the internal battery voltage, which changes slowly during the normal period of operation but quickly when the battery is either fully charged or nearly discharged. Therefore, the battery indicator will only appear full or empty for a short time.

Most of the time, it will appear ½ or ¾ full. When the charge indicator shows ¼ charge, you will need to charge it soon. It will shut off very soon after the indicator goes to empty.

4) Automatic Shutoff: If desired you can activate the automatic shutoff feature. To activate it, press MENU  OPTIONS and then scroll to the Shutdown field with your Up/Down arrow buttons and use the Left/Right arrow buttons to choose the desired auto shut-down time (5 min, 10 min, 15 min, NONE). The auto shutdown feature is turned off (set to

NONE) in its default state.

5) LNA Power Awareness: Only turn on LNA power (to power a LNA or pre-amp) while taking measurements. Avoid powering an LNA while not actually taking measurements to extend battery run time.

6) Attempting to turn on a unit when the battery contains insufficient charge may result in beeps and/or a flash on the LCD but will not harm the unit.

Page 50 of 55

XR-3 Cable Air Module Operation Manual XR-3

AC Power

When 110VAC or 220VAC power is applied to the external AC adapter, it supplies 15VDC power to charge the battery, run the meter, and power the LNA or pre-amp. In this case, the power available to the LNA is limited to 750 mAmps to avoid overdriving the power circuit and the battery charging circuit.

DC Power

When external 12VDC power is provided from a vehicle, it supplies enough power only to charge the battery, but not enough power to run the instrument while the battery is being charged.

16. Troubleshooting / FAQs

a) My XR-3 instrument is displaying a message on the screen that says “ERROR Module not found”. Why is this message displayed? i) It means the XR-3 base instrument isn’t detecting the presence of the Cable Air module. If you encounter this message, power the unit off, remove the module, reinsert the module, and power the unit back on again. b) While I have the cable connected to the RF IN port of the meter, I don't even see any signal level shown on left bar graph. It just says "UNDER". i) Try toggling to a different channel. Perhaps the frequency you were tuned to doesn’t have an active channel present. ii) Replace top (Signal In port) F-connector barrel. Use a 7/16" wrench to loosen existing barrel. Install new F-connector barrel and only tighten to 20 inch pounds of torque with wrench after finger-tightening. Warning: Do NOT over-tighten! iii) If issue still remains, contact Applied Instruments' Tech Support department and request a RMA# to send the instrument to the factory for inspection and repair. c) Can the XR-3’s Cable Air module be used to measure CATV and Off-Air signals outside the United States? i) Yes, the XR-3 meter’s XR-CA-01 Cable Air module can be used outside the United

States, but it depends on the signal types being used in each country. Be sure to select the appropriate channel plan in the meter depending on your signal type.

For digital off-air signals, the XR-CA-01 is compatible with the 8VSB signal type, which is used in the USA (and U.S. territories such as Puerto Rico), Canada, Mexico,

Dominican Republic, Guatemala, Honduras, and South Korea.

For digital cable signals, the XR-CA-01 is compatible with the QAM64 and QAM256

(ITU-T, J.83 Annex B) signal types, which are used primarily in North America (USA,

Canada, Mexico), but also some parts of Central and South America.

For analog cable and off-air signals, the XR-CA-01 is compatible with NTSC, PAL, and SECAM, so it can be used worldwide for legacy analog cable TV and off-air testing purposes. d) My serial number is missing off the back of my XR-3 meter. How can I obtain my serial number to check with the factory if it’s still under warranty? i) Connect your XR-3 instrument to the PC, power it on, and open the FlashUpdate or

MeterMaid program. The serial number of the connected unit will be displayed in

FlashUpdate and MeterMaid if proper connection is established. ii) Turn the meter on. Then go to MENU, Versions, to see the base unit’s serial number and the module’s serial number, along with the loaded software versions.

Page 51 of 55

XR-3 Cable Air Module Operation Manual XR-3 e) While attempting to download or install the FlashUpdate application, the download just seems to stall out and not make any progress. What could be the cause of this? i) This issue is most likely caused by your anti-virus software or firewall blocking our program. Please temporarily disable your computer’s anti-virus software and firewall so it doesn’t interfere with the installation of the FlashUpdate and MeterMaid programs and the related USB drivers. If you have a hardware firewall, either standalone, or in a router, you must either modify the settings of the device to permit access to our program or you will have to entirely by-pass the router or other inhibiting hardware device. Also ensure that you are signed on as Administrator or have Administrator rights for Microsoft Windows.

If your company has a strict policy and the firewall blocks any executable files, then please contact your IT department and ask for assistance. Applied Instruments is more than happy to speak to the IT department about a work-around solution.
