The HP 53131A/132A Calibration Procedures

To Calibrate the Standard Timebase

1Connect the output of a 10 MHz house standard to Channel 1 of the Counter as shown in Figure 2-5.

Figure 2-5. Standard Timebase Calibration Setup

2Cycle the POWER key to preset the Counter.

Allow the counter to warm up for approximately 30 minutes.

3With an insulated tuning tool, turn the OSC Adjust potentiometer (located on the rear chassis of the Counter) until the frequency reading in the Counter display is 10.00000000 MHz ± 5 Hz.

The Counter will be calibrated to the house standard.

If you are not able to adjust the frequency correctly, refer to the troubleshooting section in this chapter.

This completes the Standard Timebase Calibration procedure.
