A local clock set up through the Time Management Page: This option will appear
under the name of the local clock you have set up. See for more information.
Local timescale allows a Local Clock to apply a time offset for Time Zone and DST
correction.
Amplitude : The peak-to-peak output voltage level into a 600 Ω load is adjusted by enter
ing a digital control value in this field. The level adjustment has no effect on TTL outputs,
only on AM formats. The value of 128 will cause the Mark amplitude to be about 5V
into high impedance. A value of 200 results in an output amplitude of about 9V
high impedance.
Note:
adjust the level precisely, connect an oscilloscope to the output connector when
adjusting.
Offset : Provides the ability to account for IRIG cable delays or other latencies in the IRIG
input. The Offset value is entered and displayed in nanoseconds (ns). The available Off
set range is -500 to +500 ms.
For IRIG frequency and output specifications, see "IRIG Standards and Specifications" on
page 523.
For information on IRIG output resolution, see "About the IRIG Output Resolution" on page 523.
IRIG Output: Status Window
To view the specifications of an IRIG Output , go to its Status window. For instructions, see:
"Viewing Input/Output Configuration Settings" on page 329.
The Web UI list entries for these option cards are: IRIG Out BNC, IRIG Out Fiber, IRIG Out RS-
485 .
