10. Press the Ch 1 Enable button on the instrument to enable the channel 1 output.
11. Press the Play button on the instrument to output the signal.
12. Press the All Outputs On/Off button on the instrument to output the
waveform.
13. Measure the output voltage on the digital multimeter and note the value as
Measured_voltage_1 .
14. Use the following formula to compensate the voltage for the 50 Ω BNC
termination:
V_high = [( 50) / (2 Term_R)] Measured_voltage_1
Where Term_R is the resistance of the 50 Ω BNC termination measured in
step 3 in the Measure the termination resistance procedure. (See page 2-24,
Measure the termination resistance .)
15. In the Waveform List window, select the PV_DC_Minus.wfmx waveform
on the User De fi ned tab.
16. Measure the output voltage on the digital multimeter and note the value as
Measured_voltage_2 .
17. Use the following formula to compensate the voltage for the 50 Ω BNC
termination:
V_low = [( 50) / (2 Term_R)] Measured_voltage_2
Where Term_R is the resistance of the 50 Ω BNC termination measured in
step 3 in the Measure the termination resistance procedure. (See page 2-24,
Measure the termination resistance .)
18. Verify that the voltage difference |(V_high-V_low)| falls within the limits
given in the table. (See Table 2-5 on page 2-26.)
19. Repeat steps 9 through 18 for each amplitude setting in the table. (See
Table 2-5 on page 2-26.)
20. Move the SMA-BNC adapter from the CH 1 + connector to the CH 1 –
connector and move the 50
Ω SMA termination from the CH 1 – connector to
the CH 1 + connector.
21. Repeat steps 9 through 19.
22. If you are testing a AWG70002A, repeat steps 9 through 21 for the Channel 2
output.
