    Getting Started Product Description The TEKTRONIX VITS 200 NTSC VITS INSERTER is a high quality signal generator designed for VITS and data insertion into the program signal. It provides three different modes of standby operation in the event of program line failure.
  • Page 19 23 or on lines 17 through 30. VITS can be programmed on even and odd fields or in a four-field sequence. The VITS 200 may be genlocked to either the Program signal or the EXTERNAL 1 input. If you like, you can program the same signal or external input to be inserted on more than one line.
  • Page 20 As many as 15 one-line text messages can be programmed into memory. Any one of these messages may be inserted on lines 10 through 16, or the VITS 200 can be programmed to scroll through any consecutive series of these 15 messages.

    (this takes approximately 2 seconds). BYPASS This is the manual bypass control. Pressing this button puts the VITS 200 into Relay Bypass mode; the PROGRAM INPUT is applied directly to the PRO- GRAM OUTPUT, through a delay line which matches the program channel through the instrument in normal operation.

  • Page 41 The behavior of this output when program video fails depends on how the VITS 200 is programmed to respond for Standby operation: H If the VITS 200 Standby mode is disabled, the TEST SIGNAL output will continue to provide the selected test signal, and the TEST SIGNAL menu will continue to operate.
  • Page 42 Operating Basics H If the VITS 200 is programmed to provide a test signal for Standby mode operation, the TEST SIGNAL OUTPUT will switch to that standby signal, identical to PROGRAM OUT. H If the VITS 200 is programmed to switch to one of the EXTERNAL inputs for the standby signal, the TEST SIGNAL output will switch to 0% Black.

    Pins 13, 25 REMOTE ENABLE – When pin 13 is first grounded, the Remote Control unit is enabled and the VITS 200 front panel is locked out. The Remote Control must be enabled to use any control pins: the TEST SIGNAL selection pins and the ENABLE and SELECT pins for the standby and VBI messages.
  • Page 51 Pins 22, 23 BYPASS – The BYPASS LED and BYPASS SWITCH pins work just like the BYPASS push button and indicator on the VITS 200. The BYPASS LEDs work in parallel. Both of them will light whenever the VITS 200 is in the Bypass mode of operation.
  • Page 52 Pin 10 UNLOCKED LED – This pin drives an LED, which works just like the one on the VITS 200 front panel. It lights to indicate that the VITS 200 can not acquire or maintain genlock. This indicator works whether the Remote Control is enabled or not.

    2. Press the VBI Message button, select VERT MSG 2 and ENABLE it. NOTE. Any of the vertical interval messages may be used. Message two is used here by grounding pin 2 of the VITS 200 remote connector. To use another message, ground the appropriate selection pins for it (see Table 2–5).

  • Page 55: Rs-232 Control

    Operating Basics RS-232 Control The VITS 200 may be controlled through a 3-wire RS-232 interface, or by any device that can generate or transmit commands in ASCII characters. Using XON and XOFF makes it possible to control the VITS 200 directly from an ASCII terminal, personal computer (PC), or a VM700A (See Figure 2–5).
  • Page 56 RS-232 control will permit the operator to learn the current settings of the VITS 200 and change them from the terminal. New settings may be specified by name (e.g. “LINE”) or value (e.g. “15”), eliminating the need to scroll through a list of choices as with the front panel controls or with the ground-closure remote.
  • Page 57 For best results, follow these guidelines when sending text to the VITS 200: H Send one line at a time; wait for a carriage return between lines. (The VITS 200 will send a carriage return to signal that it has executed a command only if it is in TERM mode.) 2–24...
  • Page 58 VBI and Standby message text strings must be enclosed in double quotes. H Compound headers (such as :VITS:LMOD) are limited to those predefined for the VITS 200. H A line can contain several commands, if they are separated by a semicolon (:COMMAND parameter1;:COMMAND parameter2;...), but no line may exceed 128 characters.
  • Page 59 :BYPASS ON is the RS-232 equivalent of pushing the front panel BYPASS button in, and OFF is the equivalent of releasing it. A query will return the current state of the VITS 200 mode, but will not distinguish the reason it’s in that mode.
  • Page 60 This is the first step of reinitializing the NVRAM to the factory settings. When this is ENAbled, a *RST command will reset ALL of the VITS 200 settings to the factory defaults. When REINitnvram is set to DISable, an RST command will have no effect.

  • Page 96: Test Signal Generation

    Theory of Operation The VITS 200 contains three boards: A1 Inserter, A2 Front Panel, and A3 Controller. The Front Panel board contains only momentary contact switches and a connector, and needs no further discussion. The Controller and Inserter boards interact quite intimately; therefore some of the circuit discussions will include parts of both boards.

The 12-bit Tektronix DAC, A1U65 (schematic 7), turns the data into analog voltage levels at an 8 FSC rate. A one-volt reference is generated for the DAC by A1U84 (schematic 7) and associated parts.

    It then uses the digitized color subcarrier burst to determine the tangent of the phase angle between the system clock and the burst. This tangent is used to look up the arctangent (that is, the angle itself), which is stored in PROM A1U33 4–3 VITS 200...

There are four external inputs to the VITS 200, each of which may be selected for any lines of the vertical blanking interval just like a VITS signal.

    The source-identification signal is one line of video with up to 16 pulses on it, which can be recognized by a TEKTRONIX VM700A. The VM700A expects a start and a stop bit, but the other 14 bits (pulses) can be used to identify up to 16,384 sources (214).

    (schematic 5) level shifts the RS-232 data to and from TTL levels for the controller. The controller has two RS-232 interfaces built into it. The third control method for the VITS 200 is a ground closure remote which can be connected to the rear-panel REMOTE CONTROL connector.

    Theory of Operation the VITS 200 tries to lock to program input or EXTernal 1 input. This line switches the input to the genlock A/D (A1U43, schematic 5), the back porch signal to the A/D, and the comp sync to the genlock with A1U70 (schematic 3).

    Width Modulator, so long as the input AC voltage is sufficient to maintain regulation. When the VITS 200 is first turned on, C113 charges through R154. When the charge across C113 reaches approximately 16V, Pulse Width Modulator U78 begins to switch Q16 on and off through the emitter drive circuitry (Q17, CR22, CR21, and associated circuitry).
  • Page 109 Jumper P18 is included for troubleshooting. Removing P18 will interrupt power to T1, which will allow inspection of U78 and the Q16 emitter drive circuits. Once U78 and Q16 have checked out, high voltage can be applied to T1. 4–14 VITS 200...
