21. Terminate the AWG's CH1:2 through CH1:4 markers using 50 Ω SMA
terminators.
22. Press the front panel All Outputs Off button (or click All Outputs Off on the
Home screen) to enable the outputs (front panel light off).
23. Enable the Channel 1 output.
24. In the Setup -> Channel tab, select Output Settings and set the Channel 1
Marker Low Level setting as shown in the first row of the following table.
(See Table 43.)

–0.5 V
25. Measure the output voltage on the digital multimeter and note the value as
Measured_voltage_2.
26. Use the following formula to compensate the voltage for the 50 Ω BNC
feed-through terminator:
Marker_Low = (Term_R + 50) / (2 Term_R) Measured_voltage_2
