Chapter 4: Testing Performance

DC Gain Accuracy Test

record the DMM voltage reading (Vdmm- column) and the scope V avg reading (Vscope-

column) in the DC Gain Test (50 W) section of the Performance Test Record.

8 Repeat step 7 for the remaining vertical sensitivities for channel 1 shown in the DC Gain Test

(50 W) section of the Performance Test Record.

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

10 Set the DC Supply voltage (External Supply Setting) to +15 mV.

11 Configure the scope to measure V avg on Channel 2.

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 DMM voltage reading (Vdmm+) and the scope V avg reading (Vscope+) in the DC

Gain Test (50 W) section of the Performance Test Record.

13 Repeat step 12 for the remaining vertical sensitivities for channel 2 in the DC Gain Test (50

W) section of the Performance Test Record.

14 Repeat steps 9 through 13 for channels 3 and 4.

15 Repeat steps 1 through 14 using 1 MW for the scope input impedance rather than 50 W. The

steps should be followed exactly except in step 4(c), you should select the 1 MW radio button

from the Impedance section of the Channel 1 Setup dialog box rather than 50 W and all values

should be entered in the DC Gain Test (1 MW) section rather than the DC Gain Test (50 W)

section.
