Performance Verification 5

Average Gain of Zoomed-Out Channel

N2820/1A User’s Guide 79

7 Set the DC power supply to –500 mV.

NOTE Although this is the recommended setting, you can use any negative

voltage less than –700 mV.

8 Connect the multimeter on the DC power supply as shown

in Figure 45 on page 77.

9 Record the value of –V

measured on the multimeter:

–V

10 Connect the multimeter’s leads to the banana plug on the

output of the N1022A/B as shown in Figure 46 on page 78.

11 Record the value of –V

12 Calculate the negative gain of the zoomed- out (secondary)

channel and record the result in the following line:

negative gain:

13 Calculate the average of the two gains:

average gain (zoomed- out):

14 The average gain (zoomed- out) should be 1.95 ±3%. Enter the

value gain in Table 11 on page 80.
