Failures in FlyerCalibrate

Product: Flyer

Platforms: 2000 3000 3000T 4000 4000T

Problem: FlyerCalibrate fails to match the record and output channels. There are several situations which may prevent proper calibration.

1. Inadequate source used for calibration. Most often black burst is not an adequate source. Live camera, or colorbars from a camera or bar generator are preferred. Any TBC being used on the source on Input 1 should be bypassed. Some TBCs increase the overscan of a signal as it passes through, which can put active video where the Toaster/Flyer expects back porch or blanking. Any input source must be within RS170A specifications. The Flyer is also sensitive to the luma gain and horizontal position setup of input sources (see Hot Video Output).

2. If the Toaster's program output is not terminated correctly, with the last device on the output chain terminated at 75 ohms, then the output signal will be hot compared to the input, and calibration will not be performed correctly, resulting in an error. If repeated attempts to calibrate result in a large phase error, detach the cabling on the Program Out, and place a 75 Ohm terminator on the output. If the Flyer then calibrates successfully, check the termination value on the destination devices which were attaqched to Program Out.

3. Repeated failure to calibrate with an error message indicating a phase error may indicate a faulty Flyer BNC (4000 Toaster card) or Flyer cable (2000 Toaster card). Test with a replacement to determine if this is the case.

4. Check is to see if during one of the attempts to calibrate, the test clip could have been written to one of the A/V drives, but not deleted, because FlyerCalibrate never finished. If so, the user must delete this file or the calibrate routine will try to use it.

5. Check to see if the MathIEEEdoubbas.lib in the SYS:Libs directory is the correct size (5240) and date (Sep. 2, 1992). If necessary, copy one from a known working system or Workbench disks.

6. Toaster is not properly autohued, or Toaster Center Frequency is off. It is recommended that the user make sure that the Toaster is properly calibrated before attaching and calibrating a Flyer. Refer to Autohue and Center Frequency entries.

Problem: Calibration works fine, but is not maintained if the system is powered down.

1. Try the Manual Phase adjustment program, available from your dealer, or any of NewTek's online services.

2. EEPROM may be faulty. Contact NewTek for an RMA.
