  • Page 80 Outline0 and Outline1 — contd. Test Yoke tilt correction Purpose The horizontal axis of a displayed image should line up with the horizontal axis of your monitor. Any tilt is likely due to the yoke being rotated on the neck of the CRT. A rotated yoke makes any displayed image appear rotated.
  • Page 81 Test Display size correction Purpose A too-large active video size adjustment on a monitor may cause information to be lost around the edges of the screen. A too-small active video size adjustment may make some displayed information hard to read. The correct size is needed to obtain the correct aspect ratio.
  • Page 82 Outline0 and Outline1 — contd. Method Measure the lengths of the two (2) diagonal lines. Any difference is an indication of parallelogram distortion. The difference in readings should be within the specifications of the monitor. If the difference in the readings is too far beyond spec, the monitor should be rejected and sent back for repair before the operator wastes time trying to magnet a defective yoke.
  • Page 83 Test Pin and barrel distortion correction Purpose If perfectly linear sweep signals are sent to a perfectly wound deflection yoke that’s mounted on a perfect CRT, you would not necessarily get a perfectly formed raster. Instead you would likely get a raster that had its corners stretched away from the center and resembled a pincushion.

    Controlling via the IEEE-488 Port You do not need to do anything special on the 801G* to use it’s IEEE-488 port. The default settings are for the 801G* to be a talker/listener with an ad- dress of 15. All of the commands and queries shown at the end of this chapter can be used over the port.

  • Page 189: Message Syntax

    Message Syntax Program messages are sent to the 801G* using four character ASCII upper/lower case headers. These headers can be either commands or queries. Com- mands are messages which do not require a response from the 801G*. Queries are messages which cause the 801G* to respond with the required data.

  • Page 190: Queries

    Command headers which require numeric data should be followed by at least one separator character (whitespace) then the data. Numeric data sent with a command is in decimal format. Numeric data can be represented in one of three methods; integer, float- ing point, and scaled floating point.

This varies slightly from the 488.2 standard in that the MAV bit will only be set when at least one com- plete response message is present in the output queue. A complete response message consists of response message text and a message terminator (NL).

  • Page 310 System Errors This section discusses system error messages that may be displayed by the generator from time to time. Power-on Self Test Messages The integrity of the data stored in non-volatile memory is checked every time the 801GX is turned on.
  • Page 311 last time the generator was used. This check includes each of the 300 format storage locations. All user created custom images and test sequences are also checked. If no problems are found, the generator goes on to step 3. If one (or more) items have been corrupted, a message containing a tally of the defective items is displayed for 2 seconds.

  • Page 312: Format Errors

    Power Fail Message Whenever the AC power line voltage dips below the minimum specified, this message is displayed and the generator’s microprocessor is halted. If you see this message during normal operation, it probably indicates that a power sag or short dura- tion drop-out has occurred.
