  • Page 5: Introducing Microstealth

    MODEL MS1200 Introducing microSTEALTH INTRODUCTION The MS1200 Signal Level Meter is a high performance instrument designed for cable television technicians. The durable, waterproof MS1200 makes innovative use of a graphics LCD to simplify operation. The LCD backlight makes measurements easier in crawl spaces and behind TVs.

  • Page 7: Getting Acquainted With The Keypad

    You can also print a report that lists all configuration settings including the channel plan. The MS1200 tunes from 45 to 550 MHz with an option to extend the range to 5 to 890 MHz.
  • Page 8 FULL SCAN MODE View a spectrum graph of all carrier levels in your channel plan. NAVIGATOR Instantly "travel" to any mode using the NAVIGATOR. ENTER KEY Press this key to terminate your entry or selection. 5. ALPHANUMERIC KEYS You use the alphanumeric keys to enter data while operating your microStealth.

  • Page 9: Getting Acquinted With The Screen

    Print a measurement screen, installation report, or configuration report to a serial printer. Note: The following secondary function is not available on the MS1200: FILE GETTING ACQUAINTED WITH THE SCREEN There are certain elements of the screen that will become familiar to you as you use your microStealth.
  • Page 10 Title Bar Indicators You may see indicators appear above the title bar from time to time. This is what they represent: This indicator appears in the top right-hand corner of the screen when you press the SHIFT key. This means that microStealth interprets the next key that you press to be a secondary function.
  • Page 11 A list can be either "active" or "inactive". You can tell by looking at the border. If the border is solid, the list is active and any keys that you press are directed toward it. If the border is dim, the list is inactive and is not affected by key presses.

  • Page 12: The Navigator

    THE NAVIGATOR You can easily travel to any mode using the NAVIGATOR. To access the NAVIGATOR, press the key. An icon appears on the screen for each available mode. Use the up, down, left, and right arrows to highlight the icon that represents the mode you want to use.

  • Page 13: Global Configuration

    To configure your microStealth, press the SHIFT + keys or choose the icon from the NAVIGATOR. The following screen appears: Configuration settings are divided into three categories; GLOBAL, MEASUREMENTS, and CHANNEL PLAN. Use the up and down arrows to highlight the category you want and then press the key.
  • Page 14 CONTRAST LEVEL Adjusts the contrast level of the LCD for optimum viewing. SHUTOFF TIME-OUT Sets the amount of inactive time allowed before your microStealth turns off automatically. This feature is useful for conserving battery life by preventing the microStealth from being left on accidentally when it is not in use.
  • Page 15 Baud Rate: same as your microStealth Date Bits: Stop Bits: Parity: NONE Flow Control: Xon/Xoff Important The baud rate of both your microStealth and your printer must match (see BAUD RATE). A serial to parallel converter (such as the on manufactured by Black Box Corp.) can be used for printing to a parallel printer.

  • Page 17 SCAN AUDIO CARRIERS Select YES if you want to see the audio carriers in the full scan screen. You can achieve a faster scan by omitting the audio carriers. SCAN SCRAMBLED CHANNELS Scrambled channels require more time to measure. You can achieve a faster scan by omitting scrambled channels.
  • Page 18 You can change the name of the USER DEFINED (CUSTOM) test point. Notice that the edit box appears when this test point is highlighted. When you press the key, the edit box becomes active and you can enter any name up to fifteen characters long. Be sure to press the key when finished to terminate your entry.

  • Page 19: Channel Plan Configuration

    You can edit the value of the highlighted limit by pressing the key. When the edit box becomes active, enter the desired value. Be sure to press the key when finished to terminate your entry. Press the soft key to return all limits in the test point to their factory preset values.
  • Page 20 Step 1 You are asked to enter a name for the channel plan. Using the edit box, you can enter any name up to fifteen charac- ters long. Be sure to terminate your entry with the key. Press the soft key to continue with the next step. Step 2 There are several standard channel plans to use as a foundation for building your plan.
  • Page 21 You must enable a channel in order to perform measurements on it. A check mark appears in the left-hand column when the channel is enabled. When you built the plan, microStealth automatically enabled all the channels it found to be active on your system. You may want to verify that all your channels have been correctly enabled.
  • Page 22 Use the up or down arrow to highlight the desired parameter. Press key to edit the selected parameter. After completing your entry, be sure to press the key again. Enabled As mentioned earlier, a channel must be enabled in order for it to be measured.
  • Page 23 Important microStealth supports several scrambling formats including the following: Horizontal Sync Suppression Audio Offset (TV and DUAL type only) This is the offset between the video and audio carriers in MHz. Audio Offset 2 (DUAL type only) This is the offset between the video and second audio carriers in MHz.
  • Page 24 Up to six channels can be selected. To select a channel, use the up or down arrow to highlight the desired channel in the list, then press softkey. A check mark appears in the left-hand column of the list indicating that this is now a TILT channel. Also, the channel number appears in one of the six boxes above the list.
  • Page 25 These are the packages that will be available to you when you edit a channel. You will be able to select from one of these packages for each channel in the plan. To enable a package, press the softkey. A check mark appears in the left-hand column to indicate that the package is enabled.
  • Page 26 COPY REMOTE PLAN You can easily copy a channel plan from one microStealth unit to another. This saves you time when configuring multiple units. First, connect a cable between the two microStealth units. Select COPY REMOTE PLAN only on the unit that you want to copy the channel plan to.

  • Page 27: Using Microstealth

    INTRODUCTION The best way to learn about microStealth is to use it. Section 2 discusses the individual measurements available with the MS1200. Each measurement mode discussion includes detailed descriptions on how to perform the measurement as well as operating controls and indicators.

  • Page 28: Selecting Channel Packages

    SELECTING CHANNEL PACKAGES If you have configured channel packages, a list of available pack- ages will appear. From this list, you can select the packages that the subscriber has ordered. The number to the right of the package name tells you how many channels are included in each package. Use the up or down arrows to highlight a package and then press the soft key to select it.

  • Page 29: Installation Results Summary

    Note Be sure that you have enabled all of the test points that you are interested in using. The soft key is only available if there is more than one enabled test point. (see EDIT TEST POINTS). Important Only the limits that are enabled in the selected test point are checked (see EDIT TEST POINTS).

  • Page 30: The Channel List

    THE CHANNEL LIST Press the soft key or to sequence to the channel list screen. In addition to using the keys, you can also use the left and right arrows to sequence through the results screens.

  • Page 33: Adjuisting The Reference Level

    ADJUSTING THE REFERENCE LEVEL You can adjust the reference level setting of the analog bar meter using the up and down arrows. When you press the SHIFT + keys, your microStealth automatically sets the optimum reference level for you. TUNING BY CHANNEL When you are tuned to a channel, both the video and audio carriers of the channel are measured and displayed simultaneously.

  • Page 34: Measurement Hold

    MEASUREMENT HOLD You can freeze the level measurement at any time by pressing the SHIFT + keys. The measurement is retained even if the cable is disconnected from the input port. Notice that the mode icon in the upper left-hand portion of the screen appears inverted while the measurement is on hold.
