4. Choose the CalFactor item by pressing the adjacent soft key. The following items
appear on the generator’s display:
5. Choose the Self-Calibrate item by pressing the adjacent soft key.
During calibration, calibration factors and other information appear on the generator’s
display. Observe the generator’s display for error messages. If an error message
appears, make a note of it and call your technical support representative for further
assistance.
To self-calibrate the generator using the command line interface:
1. Establish a session with the generator using either HyperTerminal over a serial
connection or Telnet over an Ethernet LAN. See “ Establishing a terminal session with
the generator ” on page 31 or “ Establishing a Telnet session with the generator ” on page
34.
2. At the prompt, enter the following command:
SCAL
The generator begins the calibration procedure.
To view analog calibration factors:
Enter the following command to view the analog video red, green, blue calibration factors:
CALF ?
The generator presents the following in response:
1089, 2589, 1993, 3223, 1148, 2633, 2059, 3279, 1000, 2505, 1990, 3219,
793, 787, 3382, 3509
For an explanation of the calibration factors, see the CALF ? command in the Appendix A,
“ Command Reference .”
Calibrating frequency
All frequencies associated with the generator are derived from a common frequency
reference, which can be calibrated using the rate calibration command
RATC .
To calibrate all frequencies:
1. Load a standard format and set the horizontal rate to 100 kHz.
For example, enter the following command:
FMTL DMT0660
