Brief Functional Test

Introduction

The information in the following paragraphs contains the functional test of the key parameters of the Fluke 54200 TV Signal Generator.

If you want to check the specifications of the generator in detail, you can use the

Performance Test in the Service Manual, order number 4822 872 15185. For the

Performance Test, special TV-Test Equipment, for example, a video analyzer (Tektronix

VM700A) is necessary.

This Brief Functional Test may be used as an acceptance test upon receipt of the instrument, as an indication that repair and/or adjustment is required, or as an functional test after repair or adjustment of the instrument. This test describes a check of an instrument with all options built-in. If an option is not built-in in the instrument under test, please skip the corresponding steps.

When you have finished the Brief Functional Test or if you abort the test, you should perform RECALL 0 to set the instrument in a defined default status, see Chapter 6,

‘*RST Reset Command.’

Recommended Test Equipment

TV Receiver, Multi System with:

• Analog stereo sound

• NICAM-sound

• Teletext

• RGB & Y/C input, for example, Philips 25PT 8302

TV Receiver, NTSC-System with:

• BTSC-sound

• Closed Caption, for example, Magnavox P2783 C101 / Philips 27V505-00A

Oscilloscope with:

• TV/Line trigger for example, Fluke PM3382A/061

Self-Test Routine

After power on the instrument performs a self-test routine of the PROM, processor

RAM, stored instrument settings, calibration data, and available digital modules. After approximately 2 seconds the generator automatically recalls its instrument state before power off.

If a fault is found during the self-test this fault is indicated as follows, for example:

For detailed information see the end of Chapter 5, 'Operating Hints, Out of Range and

Error Messages.'
