Performance tests
NOTE.
This test uses the .wfmx fi les that are used in the previous test (Analog
Amplitude Accuracy). If you did not perform that test, use step 7 in the procedure
to load the
fi les, and then proceed with the following steps to activate the
8+2 markers.
5. In the Waveform List window, select (drag and drop) the PV_DC_Plus.wfmx
waveform to the work space.
6. Press the Home button on the instrument, or click the Home tab on the display.
a. Click on the Setup tab.
b. From the drop-down list under Resolution (bits), select 8+2 Mkrs .
7. Click the CH 1 Enable button on the instrument to enable the channel 1
output.
8. Press the All Outputs button on the instrument to output the waveform.
9. Make the instrument High Level setting shown in the fi rst row of the
following table:
Table 2-7: Marker high level accuracy
High level settings Accuracy limits
+ 1.4 V 1.185 V to 1.615 V
0.0 V –75 mV to +75 mV
–0.9 V –1.065 V to –0.735 V
10. Measure the output voltage on the digital multimeter and note the value as
Measured_voltage_1 .
11. Use the following formula to compensate the voltage for the 50 Ω BNC
termination:
Marker_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 .)
12. Verify that the marker High level falls within the limits given in the table.
(See Table 2-7.)
13. Repeat steps 9 through 12 for the remaining 2 rows in the table. (See
Table 2-7.)
