To Calibrate the High Stability Timebase Option
(Medium, High, or Ultra-High)
NOTE
Allow the Counter to warm up for approximately 24 hours before
performing this calibration. This calibration is unlikely to fail, unless
the Counter is not warmed up.
1
Connect the output of a 10 MHz house standard to Channel 1 of
the Counter as shown in Figure 2-7.
2
Press any one of the arrow keys until
CAL: TIMEBAS?
is displayed.
Note that the timebase choice (CAL: TIMEBAS?) only appears when the
Timebase Option is installed.
3
Press Enter key and follow the instructions in the scrolling
message that appears in the Counter display.
4
Press Enter key after each instruction.
The Counter displays
CALIBRATING
, and then it should display
TB CAL PASS
.
If the fail message is displayed (even after the Counter has been warmed
up for 24 hours), refer to the troubleshooting section in this chapter.
This completes the High Stability Timebase Option Calibration procedure.
If all tests passed, the Counter is now calibrated.
NOTE
If the counter has been disconnected from line power for over 24 hours, it
may take up to 30 days for the daily aging rate to be re-attained.
