Performance Tests (MSO/DPO5000 Series)
6. Set the Mean & St
Dev Samples to 1000 as follows:
a. Push the Wave Inspector Measure button.
b. In the Measurements Setup window, select the More tabontheleft.
c. Select the Burst Width measurement.
d. Select Statistics.
e. Click in the Weight n= box and set the value to 1000.
7. Set the sig
nal source to 240 MHz and 40 mV as shown in the test record.
NOTE. To provide consistent results, set the signal source frequency such that the
zero crossing does not occur at the beginning or end of the record.
8. Reset statistics as follows:
a. Push th
e front-panel Wave Inspector Measure button.
b. In the Measurement Setup window, select Statistics.
c. Click Reset.
d. Wait 5 or 10 seconds for the oscilloscope to acquire all of the samples
before taking the reading.
9. Check the oscilloscope performance a s follows:
a. Verify that the St Dev is less than the upper limit shown in the test record.
b. Enter the reading in the test record.
c. Rep
eat the check for each combination of oscilloscope and source signal
settings in the test record, using the method in step 3 to change the
Horizontal Scale settings.
10. Repeat the tests at 1 MΩ as follows:
a
.
S
et the sine wave generator output impedance to 1 MΩ.
b. Push the front-panel oscilloscope Vertical Menu button.
c. Set the Termination to 1MΩ.
d. Repeat steps 7 through 9 for each setting combination shown in the test
record.
