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 E
nable 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
.
Table 2-8: Marker low level accuracy
Low level settings Accuracy limits
+ 0.9 V 0.735 V to 1.065 V
0.0 V –75 mV to +75 mV
–1.4 V –1.615 V to –1.185 V
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 o utput.

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 filesthatareusedinthe–markerstestsarethesameasusedinthe+
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.
