Performance tests
NOTE. This test
uses the .wfmx files 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 files, and then proceed with the following steps to a ctivate 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 tabonthedisplay.
a. ClickontheSetup 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 first row of the
following table:
Table 2-7: Marker high level accuracy
High level settings Accuracy limits
+1.4V 1.185Vto1.615V
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 = (Term_R + 50) / (2 Term_R) Measured_voltage_1
Where Term_R is the resistance of the 50 Ω BNC termination measured in
step3intheMeasure 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 t he table.
(See Table 2-7.)
13. Repeat steps 9 through 12 for the remaining 2 rows in the table. (See
Table 2-7.)
