Check digital threshold accuracy (MSO5000/B only)

334
For the MSO5000/B series only, this test checks the threshold accuracy of the
digital channels. This procedure applies to digital channels D0 through D15, and
to channel threshold values of 0 V and +4 V.
1. Connect the P6616 digital probe to the MSO5000/B series instrument.
WARNING. The generator is capable of providing dangerous voltages. Be
sure to set the generator to off or 0 volts before connecting, disconnecting,
and/or moving the test hookup during the performance of this procedure.
2. Connect the DC voltage source to the digital channel D0.
If you are using the Fluke 9500 calibrator as the DC voltage source, connect
the calibrator head to the digital channel D0, using the BNC-to-0.1 inch pin
adapter listed in the
from the probe connector to both the corresponding signal pin and to a
ground pin on the adapter.
3. Push the front-panel Default Setup button.
4. Turn on the digital channels and set the thresholds as follows:
a. Push the front-panel D15-D0 button.
b. Select the D7-D0 tab on the left and turn channels D7-D0 On.
c. Select the D15-D8 tab and turn channels D15-D8 On.
d. The instrument will display the 16 digital channels.
e. Click in the Global Threshold box and set the value to 0.00 V.
f. Click Apply.
g. All thresholds are now set for the 0 V threshold check.
5. Set the Horizontal Scale to 5 μs/div.
