Connections
Connect the equipment as shown here.
Procedure
1
Configure the sine wave source to output a 0 dBm (600 mVpp) sine wave into
50 ohms with a frequency of 10.00002000 MHz.
2
Adjust the source amplitude such that the displayed sine wave is 600 mVpp.
3
Click Control > Factory Default .
4
Set the vertical scale of channel 1 to 100 mV/div.
5
Set the oscilloscope’s sampling rate to 100 kSa/s.
6
Set the oscilloscope's horizontal scale to 20 ms/div.
7
Set the measurement thresholds for all waveforms to a fixed voltage level of 0 V
and ±20 mV hysteresis:
a
Click Measure > Thresholds... .
b
Select Custom: level +/- hysteresis from the Thresholds drop-down list box.
c
Enter 20 mV in the Hysteresis field and 0 V in the Threshold Level field.
8
Enable a frequency measurement on channel 1.
9
On the oscilloscope, press [Stop] .
10
Press [Clear Display] .
11
Press [Run] , wait until 10 acquisitions have accumulated, and then press [Stop] .
12
Convert the average frequency value to time scale error by subtracting 20 Hz
and dividing by 10 Hz/ppm. Record the result in the Measured Time Scale Error
(ppm) column of the Time Scale Accuracy table.
