Chapter 4: Testing Performance

Offset Accuracy Test

Change the vertical sensitivity of channel 1 to 10 mV/div, press the Clear Display key, wait

for the #Avgs value (top left corner of screen) to return to 256 and then record the scope V avg

reading in the V

zero-error

column (Offset Accuracy Test tables - both the 50 W table and 1 MW

table) in the Performance Test Record section at the end of this chapter.

6 Repeat step 5 for the remaining vertical sensitivities for channel 1 in the Offset Accuracy Test

tables in the Performance Test Record section.

7 Press Default Setup, then turn off channel 1 and turn channel 2 display on.

8 Configure the scope to measure V avg on Channel 2 as follows:

a Pull down the Setup menu and select Acquisition. When the Acquisition Setup window is

displayed, enable averaging and set the # of averages to 256.

b Change the vertical sensitivity of channel 2 to 5 mV/div.

c Click the V avg measurement icon on the left side of the screen.

d When the Enter Measurement Info window is displayed, ensure that the Vavg function is set up

as follows and then click OK:

Source = Channel 2

Measurement area = Entire Display

Press the Clear Display key on the scope, wait for the #Avgs value to return to 256 and then

record the scope’s mean V avg reading in the V

zero-error

column (Offset Accuracy Test tables

- both the 50 W table and 1 MW table) in the Performance Test Record section at the end of

this chapter.

10 Repeat step 9 for the remaining vertical sensitivities for channel 2 in the Offset Accuracy Test

table of the Performance Test Record.

11 Repeat steps 7 through 10 for channels 3 and 4.

12 Ensure that each V

zero-error

is less than the corresponding V

zero-error

Limit entry in the Offset

Accuracy Test table.
