14. In the Waveform List window, select (drag and drop) the
PV_DC_Minus.wfmx waveform to the work space.
15. Click the Ch 1 Enable button on the instrument to enable the channel 1 output.
16. Press the All Outputs On/Off button on the instrument to output the
waveform.
17. Make the instrument Low Level setting shown in the first row of the table
shown below.

18. Measure the output voltage on the digital multimeter and note the value as
Measured_voltage_2.
19. Use the following formula to compensate the voltage for the 50 Ω BNC
termination:
Marker_Low = (Term_R + 50) / (2 Term_R) Measured_voltage_2
20. Verify that the marker Low level falls within the limits given in the table.
(See Table 2-8.)
21. Repeat steps 17 through 20 for the remaining 2 rows in the table. (See
Table 2-8.)
22. Press the All Outputs On/Off button to disable the channel 1 output.
23. Move the SMA-BNC adapter from the CH 1 Markers M1 + connector to the
CH 1 Markers M1 – connector and move the 50 Ω SMA termination from the
CH 1 Markers M1 – connector to the CH 1 Markers M1 + connector.
NOTE. The files that are used in the – markers tests are the same as used in the +
markers tests, but in opposite: When testing the Markers M1 – output, the marker
high level accuracy is tested using the PV_DC_Minus.wfmx file, and then the
marker low level accuracy is tested using the PV_DC_Plus.wfmx file.
24. Using the PV_DC_Minus.wfmx file that is present on the workspace, repeat
steps 7 through 13 to complete the high level accuracy test for the M1 –
Marker output.
