Procedure
1
Configure the sine wave source to output a 0 dBm (600 mVpp) sine wave into 50 ohms
with a frequency of 10.0002000 MHz.
2 Adjust source amplitude such that displayed sine wave is 600 mVpp.
3 Press the Default Setup key on the oscilloscope.
4 Set channel 1's vertical scale to 100 mV/div.
5 Set the oscilloscope sample rate to 100 kSa/s. (The resulting measurement will be
aliased.)
6 Set the scope's horizontal scale to 10 ms/div.
7 Set the scope's input impedance to 50 ohms.
8 Set the measurement thresholds for all waveforms to a fixed voltage level of 0 V and
±20 mV hysteresis.
9 Enable a frequency measurement on channel 1.
10 On the oscilloscope, press Stop.
11 Press Clear Display.
12 Press Run, wait until 10 acquisitions have accumulated, and then press Stop.
13 Convert the average frequency value to time scale error by subtracting 200 Hz and
dividing by 10 Hz/ppm.
14 Record the time scale error value as well as the time (in years) since the oscilloscope
was manufactured .
15 Compare the measured TSA value to the TSA test limits in the Performance Test Record
and record the results.
